Flying Star chart audit sheet: Palace, Mountain, Water, Year
Use a Flying Star chart audit sheet to record period, facing and sitting bearings, palace stars, annual overlay, and date before any final interpretation.
Answer First
A Flying Star chart audit sheet is a fixed checklist for recording the base period, facing and sitting bearings, nine-palace grid, mountain and water stars, annual overlay, north reference, date, source, and school convention before any interpretation. Fill it in first; read the chart second.
Definition: A Flying Star chart audit sheet is a structured record of every input a Xuan Kong (Flying Star) chart depends on: the base period, the facing and sitting bearings, the nine-palace grid with its mountain and water stars, the annual star overlay, the north reference used, the measurement date, the chart’s source, and the interpretation school. Completed first, it turns a finished-looking grid into a reproducible set of facts that a second reader can verify.
Why: A chart is only as trustworthy as its inputs. The same building yields different grids when the facing and sitting bearings are swapped, the period is mis-assigned, or the annual overlay is omitted. Writing the inputs down before interpreting forces those ambiguities to surface while they can still be corrected, and it lets a second reader rebuild the chart from the same facts.
Example: A reader completes the sheet as: “facing 202° magnetic, sitting 22°, Period 9, mountain and water star pairs recorded for all nine palaces, annual overlay marked for the lunar year in effect, declination applied per the World Magnetic Model (NOAA, 2025).” The grid can now be regenerated and verified by anyone.
Key Facts
- A Flying Star chart (Xuan Kong Fei Xing) arranges the numbers one through nine in a three-by-three grid of nine palaces for a specific building, and the arrangement changes with the building’s orientation and with time.
- The base chart is built from three primary inputs — the base period, the facing direction, and the sitting direction — and the annual overlay adds a fourth, time-based input.
- By convention, the mountain star is derived from the sitting direction and the water star from the facing direction, and every palace carries both.
- Base periods run in twenty-year blocks; the most widely published tables date Period 8 from 2004 to 2023 and Period 9 from 2024 to 2043.
- The journal Riset Arsitektur (RISA) published a 2019 paper, “Analysis of Cycle 8 Period Flying Star Feng Shui on Cycle 7 Period Residential Space Layout” (vol. 3, no. 2, pp. 188–204, LPPM UNPAR), examining how a later-period chart is applied to a residence laid out for an earlier period — a reminder that period assignment is treated as material within the tradition (Crossref metadata verified 2026-08-04; no author supplied).
- Compass readings are magnetic by default; correcting to true north requires a declination model, and the official reference is the World Magnetic Model maintained by NOAA (NOAA, 2025).
- The 2008 Cambridge University Press book An Introduction to Feng Shui devotes a chapter to “Feng shui research” (pp. 84–99) and another to “Cosmological principles, schools of interpretation and the feng shui compass” (pp. 100–117), confirming that schools of interpretation and the compass itself are recognized, contested subjects in scholarly treatment (Crossref metadata verified 2026-08-04; no author supplied).
- Flying Star readings are culturally meaningful and widely used as guidance within the tradition, but predictive interpretations are not validated by scientific testing as reliable forecasts.
Expert Explanation
The grid is reproducible; the inputs are not
Flying Star charts are deterministic: given the same base period, facing bearing, and sitting bearing, two careful calculators should produce the same nine-palace grid. That property is what makes auditing possible, and it is why disagreements between readers usually trace back to an input rather than to the arithmetic. The most common input errors are recording the facing bearing where the sitting bearing belongs, mixing magnetic and true north, and assigning the wrong base period.
What the nine palaces actually record
The chart is a three-by-three grid with one cell per palace and the center palace holding the period star at the start. Every cell carries two star numbers: by the usual convention the mountain star derives from the sitting direction and the water star from the facing direction, and both are written into each palace as the numbers move through the grid. Notation varies by source — some write the mountain star above the water star, some use the opposite corner — which is one more reason the source field on the audit sheet matters. A grid with no notation key is not re-checked.
Period, facing, and sitting define the base chart
The base period is the twenty-year block in which the chart is set, and the period number determines the star that starts in the center palace. The facing direction is the direction the building faces — commonly the direction of the main entrance or front elevation — and the sitting direction is its opposite. The water star is derived from the facing direction and the mountain star from the sitting direction, so the two star series are not interchangeable.
What counts as “the facing” is where schools diverge: some use the main door, some use the direction the rear of the building faces, and some apply different logic for apartments above ground level. That is exactly why the audit sheet carries a school-convention field. The Cambridge chapter “Cosmological principles, schools of interpretation and the feng shui compass” (2008, pp. 100–117) treats the compass itself as a subject of cosmological principle, and the RISA 2019 paper shows period questions being analyzed explicitly — both support the practical habit of recording the convention rather than assuming it. The Feng Shui Complete Guide: Schools, Space, and Limits explains how the major schools differ and where their claims end.
The annual overlay and the north reference
Flying Star practice adds a time layer: for each lunar year a star enters the center and moves through the palaces, overlaying the base chart. Because the overlay changes from year to year, the sheet must record which lunar year applies and when the measurement was taken. Without the date, an annual overlay is not checked or reproduced.
Compass work adds a second reproducibility issue. A handheld compass reports magnetic north, while most charts and tables assume true north; the difference is the local declination, and the official reference for it is the World Magnetic Model published by NOAA’s National Centers for Environmental Information (NOAA, 2025). If the sheet records magnetic or true, plus the declination value used, the reading can be corrected later without retaking it. Where to check magnetic declination before compass work explains how to obtain the local value. How to calibrate a phone compass before feng shui use covers device-level accuracy, which matters because a phone bearing can shift by several degrees between readings.
Audit first, interpret second
The Flying Star chart audit sheet exists to enforce a separation: facts first, judgment second. When the factual fields are complete, interpretation can begin, and when two readers disagree about a chart, the disagreement can be traced to a specific field instead of to an opinion. None of this makes the predictions scientific. The interpretive layer of Flying Star feng shui is culturally meaningful, but it is unverified as a reliable forecast by measurement; auditing improves consistency and accountability, not predictive power.
Decision Framework
The eleven-field Flying Star chart audit sheet
The checklist below is the core deliverable: complete it in order, from 1 to 10, and only then open the interpretation. Field 11 holds the judgment, kept deliberately separate from the facts. Every factual field records something another person can verify.
| # | Field | Record | Why it matters |
|---|---|---|---|
| 1 | Date and time | When the reading was taken, including the lunar year if known | Anchors the annual overlay |
| 2 | Building and room | Which property and space the chart describes | Prevents mixing charts |
| 3 | Facing bearing | Degrees, e.g. 202° | Feeds the water star |
| 4 | Sitting bearing | Degrees, e.g. 22° | Feeds the mountain star |
| 5 | North reference | Magnetic or true, plus declination value and source | Keeps bearings reproducible |
| 6 | Base period | Period number, e.g. 8 or 9, and the table used | Sets the center star |
| 7 | Nine palaces | Mountain/water pair for each of the nine cells | The core of the chart |
| 8 | Annual overlay | Annual star and its lunar year | Adds the time layer |
| 9 | Chart source | Hand calculation, software, or book | Documents provenance |
| 10 | School convention | Which school or method is applied | Explains interpretive choices |
| 11 | Interpretation notes | Judgment, recorded separately | Keeps facts auditable |
How to run the audit
- Fill the factual fields in order, 1 to 10, before writing anything interpretive.
- If a field is not determined — the facing is ambiguous, the period is uncertain — stop and resolve it before interpreting.
- Whenever a bearing changes, for example after recalibration or after a door change, re-audit rather than patch the old chart. What to check when a compass reading changed by three degrees lists the usual causes of a drifting bearing.
- File each completed Flying Star chart audit sheet alongside the raw readings. The Feng Shui Compass Measurement Log: Track Every Reading guide shows a lightweight way to store bearings and dates.
- Treat the sheet as the source of truth in later discussion: a disagreement about a chart should start from the recorded facts, not from the interpretation.
Re-audit after anything that could change the inputs: a renovation that moves the main entrance, a recalibrated compass, or a new lunar year. Each of those changes one field, and one changed field can change the chart.
When the audit changes the answer
Two examples of the fields doing their job:
- A chart labeled “Period 9” but computed with the 2004–2023 table quietly carries a Period 8 center star; the base-period field forces the table to be named.
- A reading taken with an uncalibrated phone compass can shift several degrees; the bearing and north-reference fields make the error visible before interpretation rather than after.
Neither example involves star values or predictions — the point is that the audit exposes input errors that would otherwise be read as chart results.
Key Takeaways
- Record before you interpret: complete the sheet first and the reading second.
- The eleven fields cover period, bearings, palaces, stars, overlay, north reference, date, source, and school convention.
- Facing and sitting bearings are the most commonly confused inputs; record both in degrees with their north reference.
- The base period and the annual overlay are both time-based; one fixes the chart’s era, the other its year, and neither should be assumed.
- A chart without a source and a school convention is not verified or compared with another reader’s chart.
- Auditing guarantees consistency, not prediction: Flying Star interpretations are culturally meaningful but not validated by scientific testing as reliable forecasts.
FAQ
What is a Flying Star chart audit sheet? It is a fixed checklist of the facts a Flying Star (Xuan Kong Fei Xing) chart depends on: base period, facing and sitting bearings, the nine-palace grid with mountain and water stars, the annual overlay, the north reference, the date, the source, and the school convention. You complete it before interpretation so the chart can be verified, reproduced, and compared with other readers’ charts.
Why must I record both the facing and the sitting bearing? The two bearings define the two star series: by the usual convention the water star is derived from the facing direction and the mountain star from the sitting direction. Swapping them produces a different chart, and the swap is invisible unless both values are written down together with the compass reference that was used.
How do I know which base period a chart belongs to? Base periods run in twenty-year blocks, and the most widely published tables date Period 8 from 2004 to 2023 and Period 9 from 2024 to 2043. Record the period number and the exact table you used on the audit sheet, because a chart labeled with one period but computed with another table will not match.
Does auditing a chart make the predictions more reliable? No. Auditing makes a chart consistent, reproducible, and comparable between readers. The interpretive predictions of Flying Star feng shui are culturally meaningful within the tradition, but they are not validated by scientific testing as reliable forecasts, and no checklist changes that.
