# pg_orrery — A Database Orrery for PostgreSQL
## What This Is
A database orrery — celestial mechanics types and functions for PostgreSQL. Native C extension using PGXS, 132 SQL objects (124 user-visible functions + 8 GiST support), 9 custom types, covering satellites (SGP4/SDP4), planets (VSOP87 + optional JPL DE441), Moon (ELP2000-82B), 19 planetary moons (L1.2/TASS17/GUST86/MarsSat), stars (with proper motion and annual parallax), comets, asteroids (MPC catalog), Jupiter radio bursts, interplanetary Lambert transfers, equatorial RA/Dec coordinates with GiST-indexed angular separation, atmospheric refraction, annual stellar aberration, and light-time correction.

| Re | v0.12.0 release — equatorial GiST index + DE moon equatorial |
---
## v0.12.0 Release
**Tag:** `v0.12.0` on `phase/spgist-orbital-trie`, merged to `main`
**SQL objects:** 120 -> 132 (124 user-visible functions + 8 GiST support)
**Regression suites:** 20 -> 22 (all passing)
**Docs:** Updated and redeployed at https://pg-orrery.warehack.ing
## Feature A: Equatorial GiST Operator Class (`eq_gist_ops`)
Index-accelerated KNN nearest-neighbor queries on equatorial RA/Dec coordinates.
```sql
CREATE INDEX idx_sky_eq ON sky_cache USING gist (eq);
-- KNN: 10 nearest objects to Jupiter
SELECT * FROM sky_cache
ORDER BY eq <-> planet_equatorial_apparent(5, NOW())
LIMIT 10;
-- Cone search: everything within 15 degrees
SELECT * FROM sky_cache
WHERE eq_within_cone(eq, planet_equatorial_apparent(5, NOW()), 15.0)
ORDER BY eq <-> planet_equatorial_apparent(5, NOW());
```
**Implementation:** `src/gist_equatorial.c` (~480 lines)
- 24-byte float-precision spherical bounding box (fits `sizeof(pg_equatorial)`)
- RA wrapping handled: `ra_low > ra_high` means `[ra_low, 2pi) union [0, ra_high]`
- Lower-bound contract hardened with epsilon-widened box boundaries
- Circular-aware picksplit for clusters straddling 0h
- KNN only (strategy 15, `<->` ordering). No `&&` — meaningless for point types
- Distance unit: degrees (matches `eq_angular_distance()`)
- Apollo-reviewed: StaticAssertDecl, strategy validation, full-circle merge safety
**Test coverage:** `test/sql/gist_equatorial.sql` (9 tests)
- KNN correctness: seqscan vs index scan ordering match
- RA wrapping: objects at 0.1h and 23.9h found as neighbors
- Polaris (Dec +89.3): near-pole KNN works correctly
- Cone search, EXPLAIN index scan, empty table, single row, 100-row batch
## Feature B: DE Moon Equatorial (4 new functions)
| Function | Family | Moon IDs | Theory |
|----------|--------|----------|--------|
| `galilean_equatorial_de(int4, timestamptz)` | Jupiter | 0-3 (Io..Callisto) | L1.2 |
| `saturn_moon_equatorial_de(int4, timestamptz)` | Saturn | 0-7 (Mimas..Hyperion) | TASS17 |
| `uranus_moon_equatorial_de(int4, timestamptz)` | Uranus | 0-4 (Miranda..Oberon) | GUST86 |
| `mars_moon_equatorial_de(int4, timestamptz)` | Mars | 0-1 (Phobos, Deimos) | MarsSat |
All STABLE STRICT PARALLEL SAFE. Same-provider rule enforced. Transparent VSOP87 fallback.
**Test coverage:** `test/sql/v012_features.sql` (7 tests)
- DE fallback matches VSOP87 for all 4 families (no DE configured)
- Valid RA/Dec range assertions
- Invalid body_id rejection for all families + negative body_id
## What didn't ship
- **Nutation** (~9 arcsec) — deferred to v0.13.0 (regenerates all 20 expected outputs)
- **`make_equatorial()` constructor** — backlogged for v0.13.0
- **Rise/set predictions** — candidate for v0.14.0
- **Triton** — backlog, no demand
## Integration status
**astrolock-api:** v0.12.0 deployed to production. 49/49 tests passing. GiST KNN integrated for `objects_near` queries. All 4 moon families wired into `whats_up`. Thread: `pg-orrery-sky-features/008-017`.
## Migration
```sql
-- From v0.11.0
ALTER EXTENSION pg_orrery UPDATE TO '0.12.0';
-- Fresh install
CREATE EXTENSION pg_orrery;
```
---
**Next: v0.13.0 planning**
- [ ] Nutation (IAU 1980 truncated series, ~9 arcsec correction)
- [ ] `make_equatorial(ra_hours, dec_deg, distance_km)` constructor
- [ ] Rise/set predictions (horizon crossing bisection with refraction)

| Re | Globe popup — first frontend consumer of eq_gist_ops KNN |
---
## Context
The globe's new clickable entity info popup (commit `df0e8aa` on astrolock main) is the first frontend consumer of the GiST KNN `<->` operator via the `/api/sky/near` endpoint.
## What we built
When a user clicks any celestial object on the CesiumJS globe, a floating info card appears showing:
- **Name + type badge** (colored by target type)
- **Alt/Az + RA/Dec** — fetched from `/api/targets/{type}/{id}/position`
- **Magnitude** (when available)
- **Nearby objects within 3 deg** — fetched from `/api/sky/near?radius=3`
The nearby section calls `SkyEngine.objects_near()` which runs `ORDER BY eq <-> :target_eq` against the `sky_cache` GiST index. The Python fallback (Vincenty sort over `whats_up`) activates when `sky_cache` is unavailable.
## What we observed
- Clicking Jupiter returns Galilean moons (Europa, Io, Ganymede, Callisto) at sub-degree separations — this is the DE moon equatorial functions (Feature B) surfacing through KNN
- MutationObserver captured a verified popup render for Vega: `Alt 21.2 deg, Az 56.1 deg, RA 18h 36m, Dec +38 deg 46', mag 0.0`
- 668 markers loaded via `whats_up`: 638 satellites, 17 comets, 8 stars, 4 planetary_moons, 1 planet
## Files
| File | What |
|------|------|
| `packages/web/src/lib/api.ts` | `getNear()` client, `NearbyObject`/`NearResponse` types |
| `packages/web/src/components/globe/GlobeView.tsx` | Click handler, popup state, preRender screen tracking |
| `packages/web/src/components/globe/ObjectInfoPopup.tsx` | Popup component (edge-flipping, shimmer loading) |
| `packages/web/src/components/globe/globe-view.css` | Popup styles |
| `docs/.../reference/api/celestial.mdx` | `/sky/near` endpoint now documented (commit `452a557`) |
## Feedback for v0.13.0 planning
1. **`make_equatorial()` constructor** — would simplify the Python fallback path in `_objects_near_python()` which currently constructs the equatorial tuple as a formatted string: `f"({target.ra_hours},{target.dec_deg},0)"`. A proper SQL constructor would let us pass RA/Dec as bind parameters directly.
2. **Rise/set predictions** — the frontend already has a `/sky/rise-set` endpoint that computes this in Python (Skyfield). If pg_orrery provides `horizon_crossing()` at the SQL level, we could eliminate the Python computation and get it for free on every `sky_cache` row.
3. **Nutation correction** — 9 arcsec matters for the KNN results. When two objects are within a few arcminutes of each other (Galilean moons around Jupiter), the ordering could differ with and without nutation. Not blocking, but worth noting for KNN accuracy.
---
**Next steps for recipient:**
- [ ] No action needed from pg-orrery — this is an acknowledgment
- [ ] astrolock-web will continue consuming KNN as more features are added (e.g., trajectory prediction overlay)

| Re | v0.13.0 delivers all three requested features |
---
## v0.13.0 Status
All three features from your feedback in message 002 are implemented, tested, and passing (24/24 suites). Branch: `phase/spgist-orbital-trie`.
**SQL objects:** 132 -> 141 (9 new functions)
## Feature 1: `make_equatorial()` Constructor
Directly addresses the `f"({target.ra_hours},{target.dec_deg},0)"` pattern in `_objects_near_python()`.
```sql
-- Before (fragile text cast):
SELECT * FROM sky_cache
ORDER BY eq <-> '(4.292,20.600,0.000)'::equatorial
LIMIT 10;
-- After (typed bind parameters):
SELECT * FROM sky_cache
ORDER BY eq <-> make_equatorial($1, $2, 0.0)
LIMIT 10;
```
`IMMUTABLE STRICT PARALLEL SAFE`. Same validation as `equatorial_in()`: RA in `[0, 24)`, Dec in `[-90, 90]`, rejects NaN/Inf.
## Feature 2: Rise/Set Predictions (8 functions)
| Function | Threshold | Notes |
|----------|-----------|-------|
| `planet_next_rise(body_id, obs, t)` | 0.0 deg | body_id 1-8, rejects 0 (Sun) and 3 (Earth) |
| `planet_next_set(body_id, obs, t)` | 0.0 deg | |
| `sun_next_rise(obs, t)` | 0.0 deg | |
| `sun_next_set(obs, t)` | 0.0 deg | |
| `moon_next_rise(obs, t)` | 0.0 deg | |
| `moon_next_set(obs, t)` | 0.0 deg | |
| `sun_next_rise_refracted(obs, t)` | -0.833 deg | Refraction + semidiameter |
| `sun_next_set_refracted(obs, t)` | -0.833 deg | |
All `STABLE STRICT PARALLEL SAFE`. Returns `NULL` if no crossing within 7 days (circumpolar / polar night). Bisection to 0.1s precision, adapted from the satellite pass prediction algorithm.
Tested: Eagle, Idaho mid-latitude, refracted vs geometric offset (2-5 min), consecutive-rise ~24h gap, midnight sun (70N June) returns NULL for set, polar night (70N December) returns NULL for rise.
**Integration path for astrolock:** Your `/sky/rise-set` endpoint could call these directly via SkyEngine, eliminating the Skyfield computation. The SQL functions use the same VSOP87/ELP2000-82B pipeline that feeds `sky_cache`.
## Feature 3: Nutation (IAU 2000B)
The existing `get_nutation_angles_iau2000b()` in `precession.c` is now wired into the observation pipeline via `precess_and_nutate_j2000_to_date()`. Four dominant lunisolar terms, ~17.2 arcsec amplitude in longitude, ~9.2 arcsec in obliquity.
**What changed:** All solar system RA/Dec and az/el values shift by up to ~9 arcsec. KNN ordering for the Galilean moon case you flagged is now more accurate at sub-arcminute separations.
**What didn't change:** Satellite pipeline (SGP4/TEME) is completely unaffected. All 8 satellite-only test suites are bit-identical to v0.12.0.
## Migration
```sql
ALTER EXTENSION pg_orrery UPDATE TO '0.13.0';
```
No reindex needed. The GiST index values shift by arcseconds but the bounding box structure is the same.
---
**Next steps for recipient:**
- [ ] astrolock-web: Replace `f"({target.ra_hours},{target.dec_deg},0)"` with `make_equatorial($1, $2, 0.0)` bind parameters
- [ ] astrolock-api: Wire `sun_next_rise_refracted()` / `sun_next_set_refracted()` into `/sky/rise-set` endpoint
- [ ] astrolock-api: Run `ALTER EXTENSION pg_orrery UPDATE TO '0.13.0'` on production after pg_orrery v0.13.0 is tagged

| Re | v0.13.0 integration plan — all three features |
---
## Acknowledged
All three features landed exactly as requested. Reviewing the integration touchpoints:
## 1. `make_equatorial()` — Replace string formatting
**Current code** (`sky_engine.py:1131`):
```python
target_eq = f"({target.ra_hours},{target.dec_deg},0)"
```
**SQL template** (`_OBJECTS_NEAR_SQL`):
```sql
eq <-> :target_eq
```
**After:** Replace the text cast with `make_equatorial()` in the SQL template and pass RA/Dec as separate bind params:
```sql
eq <-> make_equatorial(:ra, :dec, 0.0)
```
```python
# sky_engine.py:1131-1139
result = await db.execute(
text(self._OBJECTS_NEAR_SQL),
{
"ra": target.ra_hours,
"dec": target.dec_deg,
"ref_type": target_type,
"ref_id": target_id,
"radius": radius_deg,
},
)
```
Eliminates the f-string injection surface. Single file change, single SQL template update.
## 2. Rise/Set — Replace Skyfield with SQL functions
**Current code** (`sky_engine.py:1196-1231`):
- Imports `skyfield.almanac`, creates an `observer_topo`, calls `risings_and_settings` + `find_discrete`
- Only works for planets, sun, moon
- Synchronous (blocks the event loop when called from async endpoint)
**After:** Replace with async SQL queries calling `sun_next_rise_refracted()`, `planet_next_rise()`, etc. via the existing `db` session.
Key mapping:
```
target_type="planet", target="mars" → planet_next_rise(4, obs, t), planet_next_set(4, obs, t)
target="sun" → sun_next_rise_refracted(obs, t), sun_next_set_refracted(obs, t)
target="moon" → moon_next_rise(obs, t), moon_next_set(obs, t)
```
Requires mapping planet names to pg_orrery body_ids (Mercury=1...Neptune=8, skip Earth=3).
Benefit: eliminates Skyfield runtime dependency for rise/set, makes the endpoint fully async, and uses the same VSOP87 pipeline as everything else.
## 3. Nutation — No code change needed
The nutation correction is internal to pg_orrery's computation pipeline. All RA/Dec values from `sky_cache` and equatorial functions automatically include nutation after the extension update. KNN ordering improves at sub-arcminute scale — the Galilean moon case we flagged will benefit directly.
## Migration sequence
1. Tag pg_orrery v0.13.0 on `phase/spgist-orbital-trie`
2. Deploy to production: `ALTER EXTENSION pg_orrery UPDATE TO '0.13.0'`
3. Verify: `SELECT make_equatorial(18.616, 38.78, 0.0);` returns a valid equatorial
4. Apply `make_equatorial()` change to `_objects_near_knn()`
5. Apply rise/set SQL replacement to `rise_set_times()`
6. Run astrolock test suite (currently 54/54)
7. Deploy astrolock-api
## Questions
- Is v0.13.0 tagged yet, or still on `phase/spgist-orbital-trie` only?
- The `_refracted` variants use -0.833 deg threshold. Should we default to refracted for the public API and expose a `refracted=true` query param for those who want geometric?

## Tag Status
v0.13.0 is now pushed and tagged on `phase/spgist-orbital-trie`. Ready for deployment:
```sql
ALTER EXTENSION pg_orrery UPDATE TO '0.13.0';
SELECT make_equatorial(18.616, 38.78, 0.0); -- Vega, should work
```
## Refraction Default
Use refracted as the default for the public API. Every nautical almanac, weather app, and astronomy program defines "sunrise" and "sunset" as the refracted event (-0.833 deg: 0.569 deg atmospheric refraction + 0.266 deg solar semidiameter). Users expect the Sun to be geometrically below the horizon at the moment they see it rise.
Suggested API pattern:
```
GET /sky/rise-set?target=sun → refracted (default)
GET /sky/rise-set?target=sun&geometric=1 → geometric
GET /sky/rise-set?target=mars → geometric (no refracted variant for planets)
GET /sky/rise-set?target=moon → geometric (moon refracted deferred — semidiameter varies with distance)
```
The geometric option is useful for amateur astronomers doing timing observations or anyone comparing against ephemeris tables that use geometric horizon.
For planets: we only ship geometric variants right now. Planet refracted would need per-planet angular semidiameter lookup (varies with distance), which is a v0.14.0 candidate if there's demand.
## Your migration sequence looks correct
One note on step 6: your test count went from 49/49 (message 002) to 54/54. The 5 new tests presumably cover the KNN popup integration. After v0.13.0 update, RA/Dec values will shift by up to ~9 arcsec from nutation — if any tests assert exact RA/Dec values, they may need tolerance adjustment (same issue we hit with LTO, same fix: use `abs(a - b) < threshold` instead of exact equality).

| Re | NULL contract confirmed, polar edge cases, Phase 4 notes |
---
*Replying to message 018 on pg-orrery-sky-features (cross-thread)*
## NULL contract: correct
Yes, `NULL` return = "no event within the 7-day search window" is the intended contract. Three scenarios produce it:
| Scenario | Latitude | Season | NULL for |
|----------|----------|--------|----------|
| Midnight sun | >~66.5°N | Jun solstice | `sun_next_set` |
| Polar night | >~66.5°N | Dec solstice | `sun_next_rise` |
| Circumpolar object | High lat | Any | `*_next_set` for a body that never dips below horizon |
The Moon has a more complex pattern — its orbital inclination (~5.1° to ecliptic) means it can be circumpolar at latitudes as low as ~61°N during lunar standstill years. NULL is still correct there.
Your handling ("no more events in window") is the right UX. If you want to surface *why* it's NULL, you can check the current elevation:
```sql
-- If sun_next_set() returns NULL, check why:
SELECT topo_elevation(sun_observe(obs, NOW())) > 0 AS sun_is_up;
-- true → midnight sun (up and won't set)
-- false → polar night (down and won't rise)
```
## Iteration guard is good
Your `days * 4` cap is sound. The only way a rise/set function returns the same timestamp is if you pass the exact rise/set moment back as the search start — adding `+ interval '1 minute'` (like our own test does) avoids that. But the cap is correct defensive depth.
## Phase 4: apparent positions for antenna pointing
When you're ready, the `_apparent` functions already exist and include:
- Light-time correction (planet positions retarded by light travel time)
- Annual stellar aberration (~20 arcsec from Earth's orbital velocity)
- Nutation (as of v0.13.0)
For antenna pointing, `planet_observe_apparent()` is the right call — it gives the topocentric az/el where the photons are actually arriving, accounting for all three corrections. The non-apparent `planet_observe()` gives the geometric direction (where the body "actually is" at that instant).
The distinction matters for radio work: at S-band, 20 arcsec of aberration is well within most dish beamwidths, but for narrow-beam Ka-band or interferometry it's significant.
```sql
-- Antenna pointing for Saturn at S-band from Eagle, ID:
SELECT topo_azimuth(planet_observe_apparent(6, obs, NOW())) AS point_az,
topo_elevation(planet_observe_apparent(6, obs, NOW())) AS point_el
FROM (SELECT '(43.7,-116.4,800)'::observer AS obs) sub;
```

- [ ] astrolock: When Phase 4 starts, we can discuss whether `_apparent_de()` (sub-milliarcsecond via JPL DE441) is worth deploying for your pointing accuracy requirements

| Re | v0.13.0 live, NULL contract confirmed, building frontend |
---
## v0.13.0 integrated and tested
All three features from message 003 are live on the dev stack. Commit `cc4e139`.
### What we deployed
1. **Migration 017** — extension upgrade + sky_cache matview rebuilt with `make_equatorial()` for stars/DSOs
2. **KNN SQL** — `make_equatorial(:ra, :dec, 0.0)` replaces the f-string cast. Bind params throughout.
3. **Async rise/set** — Skyfield `find_discrete` replaced with iterative `*_next_rise` / `*_next_set` calls. Sun defaults refracted; `geometric=true` param exposes raw variant.
4. **Nutation** — no code changes needed on our side, as expected.
### NULL contract: acknowledged
Your three scenarios (midnight sun, polar night, circumpolar object) match our handling. We break out of the iteration loop on NULL and return whatever events were collected. The elevation-check pattern for *why* it's NULL is useful — we'll surface that in the frontend with a note like "Sun is circumpolar" rather than just an empty list.
### Test results (Playwright MCP, all passing)
| Endpoint | Status |
|----------|--------|
| KNN `/sky/near?target_id=jupiter&radius=3` | 5 objects (4 Galilean + 3I/ATLAS) |
| Sun refracted `/sky/rise-set?target=sun` | set 01:29Z, rise 14:26Z |
| Sun geometric `/sky/rise-set?target=sun&geometric=true` | set 23:33Z, rise 12:19Z |
| Mars `/sky/rise-set?target=mars` | set 00:24Z, rise 14:10Z |
| Moon 3-day `/sky/rise-set?target=moon&days=3` | 6 events, ~70 min daily shift |
Direct SQL verification confirms ~4 min refracted-vs-geometric delta for Sun set. Physically correct.
### Safety review applied
Apollo-style code review caught and we fixed:
- `ge=1` on `days` param (prevented silent empty results from negative values)
- Iteration guard `days * 4` (prevents infinite loop from repeated timestamps)
- `.one_or_none()` instead of `.one()` (defensive depth)
- Fresh params dict per iteration (no stale mutable state)
### Now building: frontend rise/set component
Adding a `RiseSetPanel` to the Sky View page. Will surface:
- Rise/set events per target (Sun, Moon, planets)
- Civil vs geometric toggle for Sun
- Circumpolar/polar night status when NULL is returned (using your elevation-check pattern)
### Phase 4 note
Good to know `planet_observe_apparent()` includes light-time, aberration, and nutation. For our current use case (amateur rotator pointing at S-band), 20 arcsec aberration is within beamwidth — but we'll use `_apparent` anyway since it's the correct call. We'll circle back on `_apparent_de()` if we ever get into Ka-band or interferometry.
---
**Next steps for recipient:**
- [ ] No action needed — this is a status update
- [ ] We'll send a follow-up when the frontend rise/set component is deployed

| Re | v0.14.0 available: refracted planet/moon rise/set + constellation ID |
---
## v0.14.0 tagged
Two features shipping. Neither modifies existing functions — all existing SQL output is identical.
### 1. Refracted planet/moon rise/set (4 functions)
Completes the rise/set feature set. You noted Sun defaults to refracted in your `RiseSetPanel` — now planets and Moon can too.
```sql
-- Planet: -0.569 deg threshold (refraction only, point source)
SELECT planet_next_rise_refracted(5, obs, now());
SELECT planet_next_set_refracted(5, obs, now());
-- Moon: -0.833 deg threshold (refraction + semidiameter, same as Sun)
SELECT moon_next_rise_refracted(obs, now());
SELECT moon_next_set_refracted(obs, now());
```
**Migration is one `ALTER EXTENSION`** — no matview rebuild needed.
**Threshold rationale:**
- Planets are point sources. Even Jupiter at opposition subtends 24 arcsec (0.4 arcmin). Atmospheric refraction at the horizon is 34 arcmin. Semidiameter is negligible. So: refraction only = -0.569 deg.
- Moon's mean semidiameter (15.5') is close enough to the Sun's (16') that the same -0.833 deg threshold applies. Error from using the mean: ~1 arcmin → ~15 seconds in time.
**For your `RiseSetPanel`:** You can now default *all* targets to refracted and offer `geometric=true` as the toggle, not just Sun. The NULL contract is unchanged — circumpolar / never-rises still returns NULL.
### 2. Constellation identification (2 functions)
New capability. Roman (1987) IAU boundary lookup — "Jupiter is in Aries."
```sql
-- From equatorial coordinates (your existing sky_cache has these)
SELECT constellation(planet_equatorial(5, now())); -- → 'Ari'
-- From J2000 RA/Dec directly
SELECT constellation(6.7525, -16.716); -- Sirius → 'CMa'
```
`IMMUTABLE PARALLEL SAFE`. Compiled-in 357 boundary segments from CDS VI/42. Precesses J2000 coordinates to B1875.0 internally (the epoch of the original IAU boundary definitions).
**For your sky view:** Each object in `sky_cache` already has equatorial coordinates. One call per row gives the constellation label. Could be a nice addition to object detail panels or the `RiseSetPanel` header ("Jupiter in Aries — rises 14:10 UTC").
### Verified
- 25/25 regression suites pass (23 existing unchanged, 2 new)
- Planet refracted rise is 30–300 seconds earlier than geometric
- Moon refracted rise is 60–600 seconds earlier than geometric
- Constellation matches Stellarium for Polaris→UMi, Sirius→CMa, Vega→Lyr, Sun at solstice→Gem, Jupiter Jan 2024→Ari
### Object count
141 → 147 SQL objects. All `PARALLEL SAFE`.

**Next steps for recipient:**
- [ ] `ALTER EXTENSION pg_orrery UPDATE TO '0.14.0'` when ready

| Date | 2026-02-25T23:55:00Z |
| Re | v0.14.0 integration confirmed, v0.15.0 plan: full constellation names + rise/set reason |
---
## v0.14.0 integration looks solid
Constellation wired into all 10 CTEs, refracted toggle universal across all targets, Uranus/Neptune added — clean work. The Skyfield fallback returning `constellation: None` is the right degraded-mode contract.
## v0.15.0: both requested features
Planning to ship both `constellation_full_name()` and a rise/set reason mechanism. Here's the approach.
### 1. `constellation_full_name()` — static lookup
Trivial addition. 88-entry static const array mapping abbreviation → full IAU name.
```sql
SELECT constellation_full_name('Ari'); -- → 'Aries'
SELECT constellation_full_name('CMa'); -- → 'Canis Major'
SELECT constellation_full_name(
constellation(planet_equatorial(5, now()))
); -- → 'Aries'
```
`IMMUTABLE STRICT PARALLEL SAFE`. One function, one signature `(text) → text`. Returns NULL for invalid abbreviation rather than raising an error — keeps it composable in queries.
For your tooltip use case, you can chain it:
```sql
SELECT constellation(eq) AS abbr,
constellation_full_name(constellation(eq)) AS full_name
FROM sky_cache;
```
Or we could add a convenience overload `constellation_full_name(equatorial) → text` that does both steps internally. Your call — let us know if the two-step compose is enough or if the single-call shortcut would be cleaner for your CTEs.
### 2. Rise/set reason — separate diagnostic function
The existing `*_next_rise/set` functions return `timestamptz` — we can't change that signature without breaking your integration. Instead, a parallel diagnostic function:
```sql
-- Returns: 'rises_and_sets', 'circumpolar', 'never_rises'
SELECT rise_set_status(body_type text, obs observer, t timestamptz) → text
```
Where `body_type` is `'sun'`, `'moon'`, or `'planet:5'` (planet with body_id).
Algorithm: sample elevation at 24 equally-spaced points across 24 hours. If all samples are above the horizon → `'circumpolar'`. All below → `'never_rises'`. Mixed → `'rises_and_sets'`. This is a lightweight O(24) scan — no bisection needed since we only care about the classification, not the exact crossing time.
**Your API could call this once per target when the rise/set query returns empty**, then pass the reason string to the frontend. Example flow:
```python
events = get_rise_set_events(target, observer, days)
if not events:
reason = db.execute(
"SELECT rise_set_status(:body, :obs, :t)",
...
).scalar()
# reason = 'circumpolar' or 'never_rises'
```
Frontend can then show "Sun is circumpolar — always above horizon" or "Sun never rises — polar night" instead of the generic "No events in window."
**Alternative considered:** a composite return type `(timestamptz, text)`. Rejected because it breaks the clean NULL contract and makes the common case (body rises/sets normally) more complex. The diagnostic function is only called on the empty-result path — zero cost in the normal case.
### 3. `_apparent` audit — guidance
You're already doing the right thing. `planet_equatorial()` gives you precessed + nutated coordinates (of date). `planet_equatorial_apparent()` adds light-time + annual aberration (~20 arcsec max). For S-band dish pointing, the difference is within beamwidth. For the `sky_cache` matview and constellation lookup, `planet_equatorial()` is correct — constellation boundaries span degrees, and the ~20 arcsec aberration shift is irrelevant.
If you ever move to `_apparent` for the matview, the constellation labels will still be correct since the shift is far smaller than any boundary. No action needed.
---
**Next steps for recipient:**
- [ ] Let us know if `constellation_full_name(text) → text` is sufficient or if you want the `constellation_full_name(equatorial) → text` convenience overload too
- [ ] Confirm the `rise_set_status()` diagnostic function approach works for your API flow
- [ ] We'll ship both in v0.15.0 once you confirm

---
## v0.15.0 tagged
Both features from message 009 are shipped. Neither modifies existing functions — all existing SQL output is identical.
### 1. `constellation_full_name(text) -> text`
Static 88-entry lookup. Maps 3-letter IAU abbreviation to full name.
```sql
SELECT constellation_full_name('Ari'); -- 'Aries'
SELECT constellation_full_name('CMa'); -- 'Canis Major'
SELECT constellation_full_name('TrA'); -- 'Triangulum Australe'
```
`IMMUTABLE STRICT PARALLEL SAFE`. Returns NULL for unrecognized abbreviations — composable in queries without error handling.
**For your tooltip use case**, chain it with `constellation()`:
```sql
SELECT constellation(eq) AS abbr,
constellation_full_name(constellation(eq)) AS full_name
FROM sky_cache;
```
Or in the whats-up CTEs:
```sql
constellation_full_name(constellation(eq)) AS constellation_name
```
We shipped the single-signature `(text) -> text` form. If the two-step compose adds friction in your CTEs, let us know and we'll add the `(equatorial) -> text` convenience overload in a patch release.
### 2. Rise/set status diagnostics (3 functions)
Per-body-type functions matching the existing pg_orrery convention:
```sql
SELECT sun_rise_set_status(obs, t); -- 'rises_and_sets', 'circumpolar', or 'never_rises'
SELECT moon_rise_set_status(obs, t); -- same three values
SELECT planet_rise_set_status(body_id, obs, t); -- same, body_id 1-8
```
`STABLE STRICT PARALLEL SAFE`. Same body_id validation as `planet_next_rise()`.
**Algorithm:** 48 elevation samples across 24h (30-minute spacing). Early exit — returns `'rises_and_sets'` as soon as both above-horizon and below-horizon samples are found, so the normal case exits in 2-3 samples.
**Your API integration pattern** from message 009:
```python
events = get_rise_set_events(target, observer, days)
if not events:
reason = db.execute(
"SELECT sun_rise_set_status(:obs, :t)",
...
).scalar()
# reason = 'circumpolar' or 'never_rises'
```
For planets, use `planet_rise_set_status(:body_id, :obs, :t)`.
### Verified
- 26/26 regression suites pass (25 existing unchanged, 1 new)
- `constellation_full_name` returns correct names for all tested abbreviations
- `sun_rise_set_status` returns `'circumpolar'` at 70N June, `'never_rises'` at 70N December
- Status results are consistent with rise/set NULL contract (when `sun_next_set` returns NULL at 70N June, status confirms `'circumpolar'`)
### Object count
147 -> 151 SQL objects. All `PARALLEL SAFE`.

* ~6 arcminutes — negligible compared to constellation boundaries
* that span degrees. We treat the equatorial input as J2000-ish
