How should you enter optional degrees when only some placements have them?

Enter a degree only when the chart source verifies it for that exact person's exact planet. Leave an unavailable optional degree blank; do not guess it, copy it from another placement, or treat a sign label as if it supplied a coordinate. A verified sign remains usable for sign-level comparison even when its degree is missing. The Synastry Comparison Report compares placements you supply, with optional degrees for selected major-aspect checks using a six-degree orb. It does not calculate natal positions from birth details.

Think of each placement in one of three states. If both sign and degree are verified, enter both in their labeled fields. If the sign is verified but the degree is not shown, enter the sign and leave the degree field empty. If the source entry itself is unclear or conflicting, pause that placement rather than completing it from memory. These states keep the data honest while preserving what is known.

For example, in a schematic comparison, Placement A may have a verified sign and degree while Placement B has a verified sign only. A sign-level comparison can still use both signs. A degree-based aspect that needs Placement B's coordinate remains unconfirmed; its missing value cannot be supplied by Placement A. Other pairs whose required positions are complete can still be checked, so one blank does not erase the rest of the comparison.

This also keeps interpretation proportional to the information available. A verified sign can support a reading of that placement at sign level, but an exact contact needs the relevant positions from both charts. If one coordinate is missing, mark only that contact as unresolved. Do not promote the missing value into a negative finding, and do not treat it as proof that no contact exists. The entry records what can be checked; it does not settle what the unavailable data would show.

That is why partial entry is useful: it separates known sign material from coordinate-dependent questions without pretending either layer answers the other.

The distinction is practical: a blank means ‘not supplied or not verified,’ not ‘no placement.’ Likewise, a known sign does not establish an exact angular relationship. To enter a verified value faithfully, first identify what the chart display actually labels as the sign, degree, and any smaller units.

What exactly should be copied from a chart position?

Start with one row in the chart's position table. Match the person first, then the planet: confirm that the row belongs to the chart you intend to enter and that its label is the placement requested by the form. A Moon row and a Venus row are different entries, even when they appear beside one another. Copy each into the field with the matching label; do not shift a value across planets or between two people's columns.

Next, read the sign and the position within that sign as separate pieces. A display may show a planet, a zodiac sign, a degree, and then smaller arcminute and arcsecond figures. Astrodienst's indexed FAQ, “General FAQ: How planet positions are displayed,” illustrates that sign-degree-minute-second format and distinguishes the smaller units from the degree. The FAQ page itself could not be opened for full review, so this point is limited to the indexed text; the form's labels determine which pieces it accepts.

Copy the degree as displayed if the receiving field asks for a degree. If the source also shows minutes or seconds, include them only when the form has a field or format that supports those units. Some forms may instead accept a decimal degree, but that does not authorize you to convert a value unless the form provides the conversion or its instructions explain the expected format. Preserve the source's stated precision rather than adding digits that are not there.

A compact chart view may omit the smaller units or show a rounded position, while a detailed table may provide more detail. Those displays do not give you permission to combine the sign from one line with extra precision inferred from another. Use a single, identifiable entry and copy only what it actually reports. If its precision is limited, the copied entry stays limited; do not make formats appear equivalent by inventing minutes, seconds, or decimal places.

A useful transcription therefore follows the row in order: person, planet, sign, degree, then any optional smaller units the form accepts. This is copying, not interpretation. Do not change a source label because a different sign description seems more familiar, and do not move to an adjacent row simply because it looks like the likely match. If a chart presents abbreviated labels, use its legend or position table to establish what the label means before entering the value.

Keep the copied entry traceable to its source row while filling the form. That makes it easier to catch a swapped person or planet before comparing placements, especially when two charts are shown side by side. A source row that supplies only the sign remains a sign-only entry; a field asking for a finer unit should stay empty if the source does not show that unit. Each field should reflect the source and the form together, not a best guess about what the omitted figures might have been.

Finally, check the destination field before typing. If it asks only for a sign, select the sign and do not place the full position in that box. If it separately requests a degree, enter the verified degree there. If the form labels a combined position field, follow its displayed format and instructions. When the field cannot accept a source unit, do not silently round or reinterpret it; retain the source entry as shown and use only the parts the form supports.

Where should an unavailable degree come from?

If a chart view gives you only a sign, keep the placement sign-only until a source verifies its position within that sign. A sign name identifies a category of zodiac placement; it does not specify the point occupied inside that category. In practical terms, the missing degree is missing chart data, not a blank that can be solved by reading more into the sign label. Preserve the confirmed part and mark the unresolved part accurately.

The next step belongs at the source of the position. Check whether the chart provider offers a detailed positions table or another view for the same chart and placement. Astrodienst's official page “Swiss Ephemeris - for 8000 years and more” describes software used to calculate planetary positions and chart data. That supports a simple distinction: a position is an output of calculation, not something encoded in the sign name by itself. Use a detailed source entry when it is available and clearly belongs to the correct person and planet. If it is not available, the sign-only record remains the honest one.

A separate calculation is another possible route, but it is a distinct calculation step with its own required inputs and conventions. Having someone's birth details in hand does not itself give you a verified degree to enter. The person must still obtain a calculated chart position from a source and confirm that it refers to the intended placement. Until then, do not estimate the missing portion, transfer a degree from another planet, or treat a likely value as confirmed. Those actions would turn an unknown coordinate into data the source has not supplied.

A separate chart source may ask for birth date, time, and place, or may present positions calculated under conventions selected by that source. Follow the source's own labels and make sure the displayed chart is the one you mean to compare. If birth time or another input is unavailable, that may affect what the source can establish; do not fill the gap with an assumed time or treat an approximate display as exact. The point here is not to standardize every chart service, but to require a traceable position before copying a degree into the report.

Keep that source task separate from the comparison task. The Synastry Comparison Report compares supplied Moon, Venus, and Mars positions, with optional degrees; it does not calculate natal positions from birth details. Its comparison step can use the entries you provide, but it cannot retrieve or repair a degree that your chart source did not verify. Enter the known sign as such and leave an unavailable optional degree empty. This preserves usable information without asking the comparison form to perform a calculation it does not offer.

A useful stopping rule is straightforward: use a degree only when a detailed chart source or a separate calculation gives you a clear, matching position. If you cannot verify it, stop at the sign. Do not delay every sign-level comparison while looking for a coordinate, and do not promote an unverified coordinate into an aspect claim. The record can be complete about what is known while remaining open about what is not. That is a valid state for comparison, not a failed entry.

What can a known sign still tell you?

A known sign still identifies the placement's zodiacal sign, so it remains available for a sign-level comparison. The missing degree limits what can be said about its exact position and any contact that depends on that position; it does not erase the sign already supplied. For this reading layer, compare the known Moon, Venus, and Mars signs as sign-level material. Keep the claim proportionate: you are comparing the stated placements and their themes at the level of signs, not establishing every possible relationship between the two charts.

That distinction is useful because interpretation has layers. A placement's sign can be considered on its own terms, while a degree-based contact asks a different question about two chart positions. One layer can be discussed when the information needed for the other is absent. The sign comparison does not fill in the coordinate; the absent coordinate does not make the known sign meaningless. Holding the layers apart lets a reader retain real context without borrowing certainty from a calculation that has not been made.

A schematic reading sequence makes the boundary visible. First, write down each confirmed planet/sign pair for each chart, keeping person and planet labels attached. Second, compare the corresponding Moon, Venus, or Mars material as sign-level themes, naming the actual signs supplied rather than importing assumptions about an unprovided placement. Third, keep questions that require exact positions in a separate unresolved category until those positions are verified. This sequence is a way to organize known information, not a claim that every astrological tradition assigns the same weight to sign relationships.

Keep the planet label attached during that comparison. The sign by itself is not a free-floating personality description: the reader is considering a particular supplied Moon, Venus, or Mars placement, then comparing that same placement category across charts. This prevents a sign discussion from sliding into claims about a whole person or relationship. It also makes the result easier to revisit: if a source later verifies the missing degree, the sign-level observation can remain while a separate coordinate-based question is checked.

For example, if both charts have a confirmed sign listed for a planet but one chart lacks that planet's degree, the two sign labels can still be read at sign level. The reader may describe what those supplied signs contribute to the comparison, while leaving the coordinate-dependent question unanswered. No particular sign pairing needs to be invented to make the distinction: the method is the same for whichever verified signs are present. This avoids turning a generic example into a claim about how a real couple would relate.

The language should match the layer. Call it a sign-level comparison when the conclusion comes from supplied signs. Do not call it an exact interchart aspect, because that phrase would suggest a coordinate-based relationship has been established. Equally, do not describe the sign as unusable just because the degree is absent. Both labels would overstate what the available information allows, in opposite directions.

Different interpretive traditions may emphasize sign relationships differently, so the report's method should make clear what it actually compares. Within this bounded reading, the practical value is modest but concrete: known signs preserve a layer of placement context, while verified degrees remain necessary for conclusions that depend on exact positions. Keeping those statements distinct makes partial information useful and its limits legible.

A thought to begin with

Enter a degree only when you can verify it for that person and placement; leave an unavailable optional degree blank. A known sign can still be read at the sign level, while a degree-based contact that needs the missing position remains unresolved. Don’t guess or borrow a value. Check the chart source if a particular contact matters to your question. The Synastry Comparison Report uses supplied Moon, Venus, and Mars placements and optional degrees; it does not calculate natal positions from birth details.

What does a degree add to an aspect check?

An aspect is a named angular relationship between two chart positions. To check one by degree, the method needs the positions of both bodies, because it compares their locations around the zodiacal circle and asks how far apart they are. A sign name alone identifies a broad region, not the exact point within it. Astrodienst's indexed educational page, “Introduction to Astrology: The Aspects,” describes aspects as angular relationships and an orb as the permitted deviation from an exact angle. That is the geometric layer: first establish the separation, then determine whether it falls within the method's allowance.

The word orb names that allowance around an aspect's exact angle. It gives a method room to include a contact that is close to, but not precisely at, the named relationship. It does not replace either position needed to measure the separation. If both coordinates are supplied, a degree-based check can compare them against the report's selected aspect rules. If one coordinate is absent, the separation cannot be established from the submitted pair, so the report cannot confirm that pair as an exact degree-based contact. This is a limit on that check, not a claim about what a later verified position would show.

The relevant conventional major-aspect vocabulary is conjunction, sextile, square, trine, and opposition. Astrodienst's indexed “A Brief Introduction to Astrology: Aspects” lists these five names and their conventional angles. Here the names identify the kinds of angular relationships the report checks; naming one does not yet interpret its significance. The calculation asks whether the two supplied positions meet a selected geometric condition. The interpretive question comes after that: what might this contact mean between these planets, and how should it sit beside the sign placements and other contacts? Keeping these steps separate prevents a label from being mistaken for a complete reading.

This also explains why a pair of sign labels cannot stand in for a degree-based aspect result. Sign-level comparison has its own interpretive use, as the earlier section explains, and some traditions also consider relationships between signs. But such a reading does not provide the exact angular separation used by this report's degree-based check. The two statements can coexist: a sign-level relationship may be considered within a tradition, while the report leaves a degree-confirmed contact open when its required coordinate is unavailable. Neither statement needs to cancel the other.

A useful way to read an aspect label, then, is as a bounded finding: it says that the supplied pair met the chosen angular rule. It does not by itself describe the whole relationship, rank all placements, or say how either person will act. Those broader judgments require interpretation across the relevant chart material. Geometry makes the comparison reproducible by identifying what is being measured; it does not dictate every meaning assigned to the result. The next question is how narrowly this report draws the allowance around each selected angle.

The need for two coordinates follows directly from what the check compares. Each position contributes a location, and an aspect describes a relation between those locations, not a quality contained in either sign by itself. A complete pair therefore makes a particular question answerable under the chosen geometry. A partial pair may still support other kinds of reading, but it cannot settle this relational measurement. This is why the report treats sign interpretation and aspect checking as adjacent layers rather than substitutes. A contact's name is a compact description of a measured relation; it is not a shortcut around the underlying entries or an interpretation of the entire synastry.

This distinction helps keep the conclusion proportionate: a qualifying aspect is a specific chart relation that can be discussed, while its meaning depends on the interpretive frame applied to it.

How should the six-degree setting be read?

The report checks its selected major aspects within a six-degree orb. Read six degrees as the report's inclusion threshold under its chosen method: a contact within that allowance can qualify for the relevant check, provided the needed positions are present. It is a rule for deciding which angular separations enter this report's aspect list. It is not a probability that two people will get along, a score of how strongly they feel a contact, or a rating of the relationship. The number describes the method's boundary, not the people being compared.

Astrodienst Astrowiki's indexed entry “Orb” notes that astrologers use varying orb rules. That narrow point matters because a threshold belongs to an interpretive practice; it should not be presented as a single boundary that every astrologer must use. The six-degree setting comes from the saved report specification. Astrodienst's indexed description supports the distinction between a declared method and a universal rule, but it does not supply or prove the report's setting. Keeping those sources of authority clear lets readers understand both what this report does and why another practice may frame its checks differently.

A different orb convention can change which near-angle contacts a method discusses. That is a methodological difference, not a change to the positions entered. Someone who prefers another convention may read the same chart data through that preferred approach, while the report continues to apply its stated six-degree boundary. Neither threshold, by itself, settles how much interpretive weight a qualifying contact deserves. Inclusion answers a limited question: does this pair meet the report's selected geometric condition? The answer does not tell you whether that aspect dominates the comparison or how it should be understood alongside other placements.

The boundary also cannot compensate for missing information. An orb measures tolerance around an exact angle after the separation between two positions can be calculated. It cannot supply an unknown position or turn a sign label into a coordinate. If one required placement is unavailable, widening or otherwise reconsidering an orb would not establish the pair's separation. The relevant next step is to obtain the missing position from a reliable chart source if that particular contact matters; until then, the six-degree rule has no complete pair to assess. This keeps data completeness separate from the choice of threshold.

So when reading a result, keep three questions distinct: what positions were supplied, whether their separation falls within this report's stated allowance, and what interpretive meaning to give any included contact. The six-degree setting answers only the middle question, within this report's selected method. A reader may reasonably use another interpretive orb convention, and the resulting set of contacts may differ. That preference changes the method applied to the same entries; it does not alter what those entries say or justify filling in a position that was never verified.

The threshold should also be read consistently across a result. It is the same declared allowance that frames the report's selected checks, rather than a slider for changing the meaning of an individual pair after seeing its label. A result near the method's boundary is still classified according to that boundary; the threshold does not imply a separate certainty scale or an emotional intensity measure. If a reader studies the placements through another tradition, that reader can make the alternative convention explicit and interpret accordingly. Doing so creates a different reading method, while preserving the original report's meaning as a result produced with its specified setting.

Why is an orb a declared setting rather than missing data?

Technical writing about orb estimates can show how a particular estimate was produced; it cannot turn that estimate into a universal setting. In “Estimation of aspect orbs by the computer,” Kyösti Tarvainen presents a procedure and applies it to selected chart groups. One example concerns eminent mathematicians and a control group. The paper reports an estimated maximum orb of eight degrees for the aspects selected in that example. Its value here is methodological: a number belongs to the sample, chart material, and procedure that produced it. It does not establish the threshold for every interpretive practice, and it says nothing about an unprovided placement in a separate comparison.

For the mathematician comparison, the article reports birth data for 1,849 eminent mathematicians and 910 controls. The charts used for this calculation were set for noon. That procedural choice matters to how the example should be read: the reported result comes from the chart material the researchers assembled and the calculation they applied to it. It is not a table of exact birth-time positions for every individual in a couple asking for a synastry reading. Naming the groups and the noon setting keeps the estimate attached to its actual input conditions instead of letting “eight degrees” travel on its own as though it were an unqualified rule.

Tarvainen's example tested 13 selected aspects, described in the article as specified conjunctions, squares, trines, and oppositions. The result was an eight-degree estimate for that selected set under the article's procedure. The selection is part of the result, too: it does not say that every aspect type, every pairing, or every chart question was assessed by the same calculation. Nor does the article report a synastry judgment about the people represented by any two charts. It estimates a boundary for a particular computational exercise across chart groups. That scope is what makes the figure useful to cite accurately, and what limits what a reader can reasonably infer from it.

The article also states that its estimates depend on how much data are available and may carry an inaccuracy of about one degree. This qualification belongs beside the reported estimate, not in a footnote of the reader's reasoning. It means the numerical result is conditional on data availability as well as on the chosen sample and procedure. The article's own caution does not authorize an editor or reader to substitute another value for the report's setting, or to treat uncertainty in one estimation process as a way to reconstruct a missing natal coordinate. It describes uncertainty within that exercise; it does not supply a degree that another chart source has not shown.

This is the logical difference between an orb setting and missing data. An orb setting specifies an allowance within a stated method after positions are available for that method's check. Missing data means an input needed for a particular comparison has not been supplied or verified. A published estimate, whether eight degrees in this example or another value in another method, cannot stand in for the absent position itself. The comparison report's six-degree setting is its declared boundary for selected major-aspect checks. Tarvainen's article neither sets that product boundary nor gives a reason to change it. The two numbers answer different questions: one is a result in a specific article's computational example; the other is the report's fixed operating convention.

A reader can therefore keep the article in its proper role. It illustrates why a numerical orb should be attributed to a method and its inputs, rather than presented as a universal astrological constant. Its mathematician and control samples, noon chart calculations, chosen aspects, and qualified estimate describe the example the article actually makes. They do not decide what another astrologer must use, whether a supplied pair qualifies under this report, or what an individual relationship means. For the report, use the stated six-degree setting when the needed entries are available. If a position is absent, the setting remains declared while that pair's degree-based check remains unavailable.

Which comparisons remain available when only some degrees are present?

Availability is best tracked by comparison pair, not assigned once to an entire chart. Make a small working grid with one row for each pair you may want to consider, and record whether both source signs and both degrees are known. The row tells you what that pair can support. A missing entry in one row does not automatically change the status of other rows whose placements are complete. This pair-by-pair view keeps partial information local: the reader can distinguish what is ready for comparison from what still depends on checking a source.

When both placements have verified signs and degrees, that pair is eligible for the report's selected aspect check under its declared method. “Eligible” describes the available inputs, not a result in advance: the comparison still has to determine whether the positions meet a selected condition. It also does not rank the pair above another placement. A row with complete entries can be checked even if another planet's degree is missing elsewhere. Keep the person and planet labels attached as you review each row, so a complete coordinate from one placement is not accidentally carried into a different pair.

When both signs are known but one or both degrees are absent, the sign-level material remains available for that pair. The exact degree-based contact stays unresolved because its needed coordinate or coordinates are not in the entry set. Marking the row this way preserves two facts at once: the signs are known and usable at their own level, while the specific contact question is still open. This is not a half-confirmed aspect. It is a sign comparison with no degree result yet. Other rows that use complete placements retain their own status and need not wait for this one.

A third row state applies when a source sign itself is uncertain. In that case, do not treat the placement as a confirmed sign-level input, and do not use a guessed sign to form a degree-based pair. Leave that placement pending verification. The uncertainty attaches to every comparison row that depends on it, because each such row inherits the unresolved source entry. Rows involving other confirmed placements do not inherit it merely because they appear in the same chart or report. The grid makes that dependency visible without suggesting that the uncertain placement has vanished from the chart; its value is simply not established in the material being compared.

A compact availability model can be written in three states: verified sign plus verified degree means the pair may proceed to its selected aspect check; verified signs with a missing degree mean sign-level comparison remains while the exact contact waits; uncertain source sign means both interpretive use of that placement and a degree check involving it wait. These are data states, not judgments about the meaning or importance of a placement. They also prevent an all-or-nothing conclusion: completeness belongs to the pair being assessed, and the status of one incomplete pair does not spread to unrelated complete pairs.

This distinction is useful when several placements are entered together. Review each pair according to its own source entries, rather than letting the least complete row define the entire comparison. If a pair is complete, assess it under the report's selected method. If only its signs are confirmed, keep it at sign level. If a sign is in doubt, leave dependent comparisons pending until that source entry is clarified. A reader may choose to wait for a fully populated set before reviewing anything, but that is a personal workflow choice. It is not required by the pair-by-pair availability of the information already confirmed.

When should a near-boundary display be checked again?

Check the source again when two displays give conflicting sign or position information, or when one display is too abbreviated to tell which number belongs to which field. Do not round a displayed position into a neighboring sign, and do not combine a sign from one view with extra precision that another view does not support. If the entries disagree, leave that placement uncertain until you can verify it. A plausible-looking value is not a substitute for a consistent source record.

Astrodienst's “General FAQ: How planet positions are displayed” distinguishes the sign and degree from the smaller arcminute and arcsecond figures that may follow in a position display. For transcription, preserve the provider's full label and the figures in the fields as shown. The displayed precision belongs to that entry; it does not license reconstructing digits that are absent from a compact view. When the input form accepts only a sign or a degree field, copy only what its labels support and leave unavailable precision blank. This keeps a clear source entry intact without creating a more exact one than you have.

If the provider offers a detailed position table for the same chart, compare the complete entry there with the compact display and use the detailed entry once the values agree. Keep the planet, chart, and sign attached to the value while checking: an unlabelled number or a value from another person's chart cannot resolve this placement. If the detailed and compact views still conflict, do not choose between them by intuition or by preferring whichever value produces a more familiar interpretation. Mark the sign or degree as unverified and pause only comparisons that depend on that disputed entry. Check that the detailed row names the same body and chart before relying on it; matching numerals alone do not establish that two screens refer to the same placement. If the provider's view cannot settle that identity or discrepancy, keep the entry unresolved and return to the source that produced it.

A compact display that is internally consistent is not automatically an error. Use the source's own precision when it supplies a readable, unambiguous value; a shorter format may simply omit finer detail that the comparison does not require. The useful trigger for checking is a real ambiguity: conflicting signs, unclear field labels, or a mismatch between views that matters to the comparison. This is a data-quality exception. It does not turn every placement near a sign boundary into a separate degree-theory problem, and it does not change the sign simply because a reader suspects rounding.

The practical rule is to preserve what the source actually verifies. Copy its complete label, avoid adding unsupported precision, and seek a clearer display only when the source views conflict or cannot be read reliably. Until that conflict is resolved, keep the placement pending rather than forcing a sign-level reading or an exact contact from uncertain inputs. Other pairs based on independently verified placements can still be reviewed on their own.

How should confirmed contacts sit beside sign themes?

A clear reading keeps the data layer, the aspect check, and the interpretation in view as separate steps. First establish which supplied placements are verified. Next review only contacts that qualify under the declared aspect convention. Then place those contacts beside the sign-level themes and the other relevant placements, rather than treating one aspect label as the whole comparison. This order is an editorial synthesis for a transparent reading, not a universal astrological law.

The signs and the aspects answer different questions. Sign themes describe placement meanings at sign level; a confirmed aspect describes a qualifying angular relation between two positions under a chosen rule. A contact therefore adds a specific relationship between placements, but it does not erase their signs or explain every dimension of the comparison by itself. Keeping both layers visible makes it easier to distinguish what comes from the supplied sign descriptions, what comes from a selected geometric check, and what is the reader's interpretation of their combination.

In “What Is Synastry? Classical Relationship Astrology,” practitioner Sira Nur Uysal describes reading interchart contacts within the broader chart context. That is one practitioner approach: a contact is considered alongside the wider pattern rather than taken as a self-sufficient verdict. Some readers instead foreground the tightness or prominence of particular contacts. These emphases can coexist as interpretive choices, but neither the practitioner account nor the existence of a confirmed aspect establishes one mandatory hierarchy for every synastry reading. State the approach being used and keep its claims proportionate to its scope.

For this report, the operational sequence is to retain sign themes as their own layer, review eligible selected major contacts under the stated six-degree convention, and then interpret each contact in context. Eligibility means the supplied inputs allow that check and the contact meets the selected rule; it does not mean the aspect must dominate the reading. A contact label identifies a particular relation under the method. Its interpretive weight still depends on the placements involved and on the wider comparison, so avoid translating a single label into a complete account of how two people relate. In practice, name the convention before describing the contact so a reader can tell whether the label comes from this report's selected checks or from a different interpretive approach. That small distinction makes comparisons easier to follow when two readings emphasize different features.

This order also helps when the available placements are uneven. A confirmed contact can be discussed on its own basis while a pair without the needed degree remains unresolved at the aspect layer. Sign themes from known placements remain distinct from that pending check. The comparison need not collapse into either a list of contacts or a collection of sign descriptions; each layer contributes a different kind of information. Make clear which statement is a supplied placement, which is a qualifying contact, and which is an interpretive connection drawn between them.

The Synastry Comparison Report uses supplied Moon, Venus, and Mars placements and selected major contacts, with missing-data limits. Read its output in the order the information supports: identify the placements provided, note which selected contacts qualify, and interpret those contacts beside the sign themes rather than in isolation. A reader who prefers to start with the broader chart context can make that preference explicit and still keep the evidence layers clear. The useful standard is transparency about the sequence and convention, not a claim that one order settles the meaning of every chart comparison.

What should you do if a specific contact matters to your question?

Pause to verify a missing entry when the answer you want depends on that particular degree-based contact. If your question concerns the supplied sign themes, or another comparison whose required placements are complete, you can work with those layers now. The unresolved degree does not make those separate questions unanswerable. This is a proportional choice: spend time resolving the input that controls your question, while leaving unrelated comparisons free to proceed on their own verified information.

A useful test is to name the conclusion you are trying to reach. If it is a broad comparison of known Moon, Venus, or Mars signs, the sign information can be considered at that level. If you are asking whether two specific placements form a selected major aspect, both positions are needed for that check. Return to the chart source for the missing position, making sure it belongs to the same person and placement under consideration. Until a source verifies it, the contact cannot be confirmed or ruled out. The gap describes the available information, not the answer the absent value might produce.

This distinction helps prevent two opposite errors. Treating an unresolved contact as absent turns a blank into a negative finding; treating it as present supplies a value the chart record has not established. Neither move helps answer the named question. Keep that one contact open, and continue only with conclusions supported by the other entries. If the sought interpretation genuinely turns on that contact, waiting for the source check may be worthwhile. If it does not, postponing all other work adds delay without adding information to the comparisons already supported.

There is no technical need to make every part of a comparison wait for the least complete entry. A reader may prefer to gather all positions before looking at anything, for convenience or to keep one review session together. That is a reasonable workflow choice. It differs from what the data require: complete pairs can be considered, known signs can support sign-level interpretation, and the specific missing-degree question can remain pending. The practical decision is therefore local. Verify when the answer depends on the missing value; otherwise proceed at the level the confirmed entries support, and return to the unresolved pair only if it becomes material to the question.

Consider how the decision changes with the question, not with the size of the blank. A reader comparing two verified sign descriptions can make that comparison without an exact contact claim. A reader asking whether a named pair qualifies under the report's selected aspect method needs the missing position before reaching that narrower answer. If the source can provide it, checking removes that specific uncertainty. If it cannot, record the boundary plainly: the sign-level question may still be considered, while the aspect question has no verified result. This keeps the effort aligned with the decision at hand. It also avoids turning a technical gap into pressure to delay every interpretation or, at the other extreme, into permission to state more than the available placements support.

What is the next useful step?

Check each chart label against its source, then enter the sign and any degree that the source actually provides. Leave an unavailable optional field blank. If a particular aspect question matters to your reading, decide whether returning to the chart source is worthwhile; if no verified position is available, leave that contact open while you use the other supplied information at its own level, without treating one open question as a reason to discard usable information already in hand.

Enter the information you have, with unavailable optional fields left empty, and read the comparison in light of those inputs. It will not fill a missing placement for you.

If you are ready to compare the verified entries, [Compare our placements](/compatibility-test). If you want to check one unresolved degree first, do that at its chart source, then return with the confirmed value. Either way, keep your next step tied to the question you actually want the comparison to address.

A little more clarity

Can I compare placements if only some degrees are available?

Yes. Enter verified degrees and leave unavailable optional fields blank. Known signs remain available for sign-level interpretation; a degree-based contact requiring a missing position stays unresolved. The Synastry Comparison Report uses supplied Moon, Venus, and Mars placements and optional degrees, and does not calculate natal positions from birth details.

  • General FAQ: How planet positions are displayed

    The position-format explanation distinguishes the sign and degree from the arcminute and arcsecond figures that may follow; use it only to teach faithful transcription of the source display, not to infer a chart position.

  • Swiss Ephemeris - for 8000 years and more

    Astrodienst describes Swiss Ephemeris as software for calculating planetary positions and chart data; a calculated position is an output of a calculation process, not something recoverable from a sign label alone.

  • Introduction to Astrology: The Aspects

    Astrodienst's indexed educational text describes aspects as angular relationships within the ecliptic and an orb as the allowed deviation around an exact angle; it indicates that a stated orb belongs to a method.

  • Orb

    Astrodienst Astrowiki's indexed text says astrologers vary in their orb rules and that orb size depends on interpretive practice and aspect factors; this supports treating six degrees as this report's explicit convention, not a universal threshold.

  • Estimation of aspect orbs by the computer

    Kyösti Tarvainen's technical article describes an estimation procedure and applies it to selected chart groups; in the mathematicians example it reports an estimated maximum orb of 8° for specified aspects. This is an example of a data- and method-bound estimate, not evidence for this report's six-degree setting or a universal synastry rule.

  • What Is Synastry? Classical Relationship Astrology

    Practitioner Sira Nur Uysal presents one interpretive approach that compares two natal charts and reads interchart contacts in context with the broader chart; use as an attributed example of interpretive method rather than a universal protocol or empirical finding.

  • A Brief Introduction to Astrology: Aspects

    Astrodienst Astrowiki's indexed entry lists the five major aspects and their conventional angles; use only to identify the selected major-aspect vocabulary relevant to the report, without importing its ranking language as the report's interpretation.
