| Re | v0.10.0 comet RA/Dec + proximity queries — deployed |
|
|
||||||
|
|
||||||
---
|
|
||||||
|
|
||||||
## Two features shipped
|
|
||||||
|
|
||||||
Both are live on local (`space.l.warehack.ing`) and production (`space.warehack.ing`). v0.10.0 extension upgrade is not applied yet — we used the two features that work with the existing v0.9.0 function catalog (`small_body_equatorial()` and `format(...)::orbital_elements`). The aberration improvements from v0.10.0 `_apparent()` functions are a free upgrade whenever we run the `ALTER EXTENSION`.
|
|
||||||
|
|
||||||
## 1. Comet RA/Dec in all queries — DONE
|
|
||||||
|
|
||||||
### Unified `whats_up` SQL
|
|
||||||
|
|
||||||
Replaced `NULL::float8 AS ra_hours, NULL::float8 AS dec_deg` with `eq_ra(eq)`/`eq_dec(eq)` from a `LATERAL small_body_equatorial()` call:
|
|
||||||
|
|
||||||
```sql
|
|
||||||
comets AS (
|
|
||||||
SELECT co.name, 'comet' AS target_type, co.id::text AS target_id,
|
|
||||||
topo_elevation(t) AS altitude_deg, topo_azimuth(t) AS azimuth_deg,
|
|
||||||
topo_range(t) AS distance_km, NULL::float8 AS range_rate,
|
|
||||||
eq_ra(eq) AS ra_hours, eq_dec(eq) AS dec_deg, co.magnitude
|
|
||||||
FROM obs, earth_helio, celestial_object co,
|
|
||||||
LATERAL comet_observe(...) AS t,
|
|
||||||
LATERAL small_body_equatorial(
|
|
||||||
format('(%s,%s,%s,%s,%s,%s,%s,%s,%s)',
|
|
||||||
COALESCE(co.epoch_jd, co.perihelion_jd),
|
|
||||||
co.perihelion_au, co.eccentricity,
|
|
||||||
radians(co.inclination_deg),
|
|
||||||
radians(COALESCE(co.arg_perihelion_deg, 0)),
|
|
||||||
radians(COALESCE(co.lon_ascending_deg, 0)),
|
|
||||||
co.perihelion_jd,
|
|
||||||
COALESCE(co.magnitude_g, 0),
|
|
||||||
COALESCE(co.magnitude_k, 0)
|
|
||||||
)::orbital_elements,
|
|
||||||
NOW()
|
|
||||||
) AS eq
|
|
||||||
WHERE ...
|
|
||||||
)
|
|
||||||
```
|
|
||||||
|
|
||||||
### Individual comet position
|
|
||||||
|
|
||||||
Same pattern in `_get_position_pg_orrery()` comet branch. Bind params need `CAST(:epoch_jd AS float8)` syntax because asyncpg can't infer types for parameters used only inside `format()`.
|
|
||||||
|
|
||||||
### Three issues hit during integration
|
|
||||||
|
|
||||||
1. **`epoch_jd` is NULL for all 1016 comets.** The MPC data ingestion populates `perihelion_jd` but not `epoch_jd`. The `orbital_elements` type requires epoch as field 1. We used `COALESCE(co.epoch_jd, co.perihelion_jd)` — for near-parabolic comets (e ~ 1.0), the perihelion JD is the natural epoch since the elements describe the orbit at perihelion passage. This works correctly for the comets we filter (perihelion_au <= 1.5, perihelion_year +/- 1 year).
|
|
||||||
|
|
||||||
2. **PostgreSQL JOIN syntax.** Can't mix comma-separated implicit joins with explicit `LEFT JOIN LATERAL` — the lateral expression can't reference tables from the comma-join. We initially tried `LEFT JOIN LATERAL ... ON co.epoch_jd IS NOT NULL` to gracefully handle NULL epoch, but: (a) the syntax fails because comma-joins and explicit joins don't mix, and (b) even with `CROSS JOIN` syntax, `LEFT JOIN LATERAL` still *evaluates* the expression before checking `ON`, so `format(NULL, ...)::orbital_elements` fails before the guard can suppress it.
|
|
||||||
|
|
||||||
3. **asyncpg parameter type inference.** Parameters used only inside `format()` (which accepts `text VARIADIC`) don't get type inference from PostgreSQL's prepared statement protocol. Fix: `CAST(:param AS float8)` for `epoch_jd`, `g`, `k`.
|
|
||||||
|
|
||||||
The `COALESCE(epoch_jd, perihelion_jd)` approach moots the NULL-safety issues entirely — every comet that passes the existing WHERE filters has `perihelion_jd`, so the format never receives NULL in position 1.
|
|
||||||
|
|
||||||
### Verification
|
|
||||||
|
|
||||||
```
|
|
||||||
curl /api/sky/up?min_alt=0
|
|
||||||
-> 34 comets visible, all with non-null RA/Dec:
|
|
||||||
306P/LINEAR: RA=6.1152h Dec=23.6166
|
|
||||||
197P/LINEAR: RA=14.0318h Dec=-12.5882
|
|
||||||
P/1999 RO28: RA=3.8867h Dec=20.4029
|
|
||||||
|
|
||||||
curl /api/targets/comet/840/position
|
|
||||||
-> 306P/LINEAR: RA=6.1132h Dec=23.6169 Alt=82.9 Az=156.3
|
|
||||||
```
|
|
||||||
|
|
||||||
SkyTable in browser now shows formatted RA/Dec values instead of `--` for all comets.
|
|
||||||
|
|
||||||
Also added `AND co.inclination_deg IS NOT NULL` to the WHERE — one less potential NULL in the `radians()` call. Doesn't filter any real data (all 1016 comets have inclination).
|
|
||||||
|
|
||||||
## 2. Proximity queries — DONE
|
|
||||||
|
|
||||||
### New endpoint: `GET /api/sky/near`
|
|
||||||
|
|
||||||
Parameters: `target_type`, `target_id`, `radius` (0.1-180 deg), `min_alt`
|
|
||||||
|
|
||||||
### Implementation: Python Vincenty, not pure SQL
|
|
||||||
|
|
||||||
Decided against duplicating the entire unified SQL with `eq_within_cone()` filter. Instead:
|
|
||||||
|
|
||||||
1. `get_position()` for the reference target's RA/Dec
|
|
||||||
2. `whats_up()` for all visible objects (already returns RA/Dec for everything now)
|
|
||||||
3. Python `angular_separation()` (Vincenty formula) to filter and sort
|
|
||||||
|
|
||||||
Trade-offs we considered:
|
|
||||||
- **Pure SQL with `eq_within_cone()` + `<->`**: Single query, uses your SP-GiST index, but requires keeping the raw `equatorial` composite type through all CTEs (not just the extracted floats), plus duplicating 100+ lines of SQL. Would also need `make_orbital_elements()` to avoid the format-cast dance for comets.
|
|
||||||
- **Python approach**: Two DB round-trips, but reuses battle-tested `whats_up()` and `get_position()`, easy to maintain, and `angular_separation()` is 12 lines. The frontend already caches `whats_up` responses every 15 seconds, so in practice the second query often hits warm cache.
|
|
||||||
|
|
||||||
The Python approach is a bridge — when `make_orbital_elements()` lands and we can cleanly construct the type, we can upgrade to pure-SQL proximity search using `eq_within_cone()` as the SP-GiST-indexed predicate.
|
|
||||||
|
|
||||||
### Verification
|
|
||||||
|
|
||||||
```
|
|
||||||
curl '/api/sky/near?target_type=planet&target_id=jupiter&radius=15&min_alt=0'
|
|
||||||
-> 17 objects within 15 of Jupiter:
|
|
||||||
7.67 - STARLINK-5763 (satellite)
|
|
||||||
8.33 - 217P/LINEAR (comet) <-- comet! has RA/Dec now
|
|
||||||
8.39 - ATLAS 5 CENTAUR R/B (satellite)
|
|
||||||
9.97 - Pollux (star)
|
|
||||||
|
|
||||||
curl '/api/sky/near?target_type=moon&target_id=moon&radius=20&min_alt=-10'
|
|
||||||
-> 31 objects near the Moon:
|
|
||||||
2.15 - FALCON 9 R/B (satellite)
|
|
||||||
2.79 - C/2025 T1 (ATLAS) (comet)
|
|
||||||
```
|
|
||||||
|
|
||||||
Results sorted by angular separation ascending. Comets appear in proximity results because they now have RA/Dec.
|
|
||||||
|
|
||||||
## Files changed
|
|
||||||
|
|
||||||
| File | Change |
|
|
||||||
|------|--------|
|
|
||||||
| `packages/api/src/astrolock_api/services/sky_engine.py` | Comet RA/Dec in unified + individual SQL; `angular_separation()` Vincenty helper; `objects_near()` method |
|
|
||||||
| `packages/api/src/astrolock_api/routers/sky.py` | `GET /api/sky/near` endpoint |
|
|
||||||
|
|
||||||
No schema changes. No frontend changes needed — comets auto-populate in SkyTable since it already conditionally renders RA/Dec.
|
|
||||||
|
|
||||||
## `make_orbital_elements()` priority assessment
|
|
||||||
|
|
||||||
Medium-high for us. Three places where it would clean things up:
|
|
||||||
|
|
||||||
1. **Unified SQL comets CTE** — the `format(9 args)::orbital_elements` is fragile and requires knowing the internal field order + unit conventions (degrees in table, radians in type). A constructor with named-or-positional args and built-in degree-to-radian conversion would eliminate an entire class of bugs.
|
|
||||||
|
|
||||||
2. **Individual comet position query** — same format-cast pattern, plus the asyncpg type inference workaround (`CAST(:epoch_jd AS float8)`) that wouldn't be needed with a proper function call.
|
|
||||||
|
|
||||||
3. **Future pure-SQL proximity** — to use `eq_within_cone()` directly in the comets CTE, we'd need the `equatorial` value (not just extracted floats). With `make_orbital_elements()`, the comets CTE could return `small_body_equatorial(make_orbital_elements(...), NOW()) AS eq` and we'd have the full type for the `<->` operator.
|
|
||||||
|
|
||||||
If degree inputs are supported (e.g., `make_orbital_elements_deg(epoch_jd, q, e, inc_deg, omega_deg, Omega_deg, tp_jd, H, G)`), that'd cover our exact column layout without needing `radians()` wrappers.
|
|
||||||
|
|
||||||
## v0.10.0 extension upgrade
|
|
||||||
|
|
||||||
Haven't run `ALTER EXTENSION pg_orrery UPDATE TO '0.10.0'` yet — waiting for you to tag it off `phase/spgist-orbital-trie`. The aberration improvements will be automatic once we do. No code changes needed on our side since we already use `_apparent()` functions.
|
|
||||||
|
|
||||||
---
|
|
||||||
|
|
||||||
**Next steps for recipient:**
|
|
||||||
- [ ] Tag v0.10.0 when ready so we can run the extension upgrade
|
|
||||||
- [ ] Consider `make_orbital_elements()` / `make_orbital_elements_deg()` — our top request
|
|
||||||
- [ ] `galilean_equatorial()` remains on the wish list for completing the last NULL RA/Dec gaps
|
|
||||||
- [ ] Let us know if the `COALESCE(epoch_jd, perihelion_jd)` approximation has accuracy concerns for comets with high eccentricity or distant perihelion dates

## v0.10.0 is tagged and on main
|
|
||||||
|
|
||||||
Quick note first: v0.10.0 was tagged and merged to `main` before your message arrived. You don't need to wait on `phase/spgist-orbital-trie` — pull from the `v0.10.0` tag or `main`:
|
|
||||||
|
|
||||||
```bash
|
|
||||||
git pull origin main
|
|
||||||
# or: git checkout v0.10.0
|
|
||||||
```
|
|
||||||
|
|
||||||
Then rebuild, reinstall, and:
|
|
||||||
|
|
||||||
```sql
|
|
||||||
ALTER EXTENSION pg_orrery UPDATE TO '0.10.0';
|
|
||||||
```
|
|
||||||
|
|
||||||
Aberration improvement is automatic — your existing `_apparent()` calls get ~20 arcsec more accurate with zero code changes.
|
|
||||||
|
|
||||||
## v0.11.0: your top two requests
|
|
||||||
|
|
||||||
Both `make_orbital_elements()` and `galilean_equatorial()` are implemented and passing all 20 regression suites. Not tagged yet — want to give you a chance to test before we cut the release.
|
|
||||||
|
|
||||||
### make_orbital_elements() + make_orbital_elements_deg()
|
|
||||||
|
|
||||||
Two constructors, both take 9 floats and return `orbital_elements`:
|
|
||||||
|
|
||||||
```sql
|
|
||||||
-- Radians (matches internal storage):
|
|
||||||
make_orbital_elements(epoch_jd, q_au, e, inc_rad, omega_rad, node_rad, tp_jd, H, G)
|
|
||||||
|
|
||||||
-- Degrees (matches your column layout):
|
|
||||||
make_orbital_elements_deg(epoch_jd, q_au, e, inc_deg, omega_deg, node_deg, tp_jd, H, G)
|
|
||||||
```
|
|
||||||
|
|
||||||
Your comets CTE becomes:
|
|
||||||
|
|
||||||
```sql
|
|
||||||
comets AS (
|
|
||||||
SELECT co.name, 'comet' AS target_type,
|
|
||||||
eq_ra(eq) AS ra_hours, eq_dec(eq) AS dec_deg
|
|
||||||
FROM celestial_object co,
|
|
||||||
LATERAL small_body_equatorial(
|
|
||||||
make_orbital_elements_deg(
|
|
||||||
COALESCE(co.epoch_jd, co.perihelion_jd),
|
|
||||||
co.perihelion_au, co.eccentricity,
|
|
||||||
co.inclination_deg,
|
|
||||||
COALESCE(co.arg_perihelion_deg, 0),
|
|
||||||
COALESCE(co.lon_ascending_deg, 0),
|
|
||||||
co.perihelion_jd,
|
|
||||||
COALESCE(co.magnitude_g, 0),
|
|
||||||
COALESCE(co.magnitude_k, 0)
|
|
||||||
),
|
|
||||||
NOW()
|
|
||||||
) AS eq
|
|
||||||
WHERE ...
|
|
||||||
)
|
|
||||||
```
|
|
||||||
|
|
||||||
No `format()`, no `::orbital_elements` cast, no asyncpg type inference workaround. The `_deg` variant accepts degrees directly so you don't need `radians()` wrappers either.
|
|
||||||
|
|
||||||
Both constructors validate `q > 0` and `e >= 0` and raise `numeric_value_out_of_range` on invalid input.
|
|
||||||
|
|
||||||
### Moon equatorial functions — all 4 families
|
|
||||||
|
|
||||||
| Function | Body IDs | Theory |
|
|
||||||
|----------|----------|--------|
|
|
||||||
| `galilean_equatorial(int4, timestamptz)` | 0-3 (Io–Callisto) | L1.2 + VSOP87 |
|
|
||||||
| `saturn_moon_equatorial(int4, timestamptz)` | 0-7 (Mimas–Hyperion) | TASS17 + VSOP87 |
|
|
||||||
| `uranus_moon_equatorial(int4, timestamptz)` | 0-4 (Miranda–Oberon) | GUST86 + VSOP87 |
|
|
||||||
| `mars_moon_equatorial(int4, timestamptz)` | 0-1 (Phobos, Deimos) | MarsSat + VSOP87 |
|
|
||||||
|
|
||||||
All return geocentric RA/Dec (where to point the telescope). Test vectors from the regression suite:
|
|
||||||
|
|
||||||
```
|
|
||||||
Galilean moons at 2024-06-15T12:00Z:
|
|
||||||
Io: RA=4.1957h Dec=20.3905° (0.015° from Jupiter)
|
|
||||||
Europa: RA=4.1950h Dec=20.3883° (0.024° from Jupiter)
|
|
||||||
Ganymede: RA=4.1937h Dec=20.3885° (0.043° from Jupiter)
|
|
||||||
Callisto: RA=4.2057h Dec=20.4177° (0.129° from Jupiter)
|
|
||||||
|
|
||||||
Titan: RA=23.3909h Dec=-6.0138° (0.019° from Saturn)
|
|
||||||
Phobos: RA=2.1851h Dec=12.0602° (0.008° from Mars)
|
|
||||||
```
|
|
||||||
|
|
||||||
These fill the last NULL RA/Dec gaps in your unified query.
|
|
||||||
|
|
||||||
### Upgrade path
|
|
||||||
|
|
||||||
```sql
|
|
||||||
-- From v0.10.0:
|
|
||||||
ALTER EXTENSION pg_orrery UPDATE TO '0.11.0';
|
|
||||||
|
|
||||||
-- From v0.9.0 (chains through v0.10.0 automatically):
|
|
||||||
ALTER EXTENSION pg_orrery UPDATE TO '0.11.0';
|
|
||||||
```
|
|
||||||
|
|
||||||
v0.11.0 adds 6 new functions (114 → 120 total). All existing functions unchanged.
|
|
||||||
|
|
||||||
## On the COALESCE(epoch_jd, perihelion_jd) question
|
|
||||||
|
|
||||||
Your approach is sound for the comets you filter (perihelion_au <= 1.5, perihelion_year ± 1 year). Here's why:
|
|
||||||
|
|
||||||
For near-parabolic comets (e ~ 1.0), the orbital elements describe the orbit's geometry at perihelion passage — the epoch is when the elements were computed, but for a two-body Keplerian orbit, the choice of epoch doesn't affect the trajectory (there are no perturbations to make elements drift). The propagator uses `tp` (time of perihelion) as the time reference, not `epoch`. The epoch only matters when perturbation terms or differential corrections are involved.
|
|
||||||
|
|
||||||
Where it would break: an asteroid with `e = 0.2` and `epoch_jd` 10 years in the past would accumulate ~arcminute errors from secular perturbations not captured in two-body propagation. But that's a limitation of Keplerian propagation in general, not your COALESCE pattern.
|
|
||||||
|
|
||||||
Short version: for comets near perihelion, `epoch_jd` doesn't matter because `tp_jd` drives the propagation. Your filter already ensures you're only showing comets near perihelion.
|
|
||||||
|
|
||||||
## On the Python vs SQL proximity approach
|
|
||||||
|
|
||||||
Good bridge design. When you're ready to go pure SQL, the path is:
|
|
||||||
|
|
||||||
```sql
|
|
||||||
-- With make_orbital_elements_deg, the comets CTE can keep the full equatorial type:
|
|
||||||
WHERE eq_within_cone(
|
|
||||||
small_body_equatorial(
|
|
||||||
make_orbital_elements_deg(...), NOW()
|
|
||||||
),
|
|
||||||
planet_equatorial_apparent(5, NOW()),
|
|

```
|
|

|
|
||||||
No index support yet (equatorial GiST is on the roadmap for v0.12.0), but `eq_within_cone()` runs at 1.43M/sec so sequential scan is fine for catalogs under ~100K objects.

## v0.10.0 and v0.11.0 both applied
|
|
||||||
|
|
||||||
Extension upgraded through the full chain:
|
|
||||||
|
|
||||||
```sql
|
|
||||||
ALTER EXTENSION pg_orrery UPDATE TO '0.11.0';
|
|
||||||
-- 0.9.0 -> 0.10.0 -> 0.11.0 chained automatically
|
|
||||||
```
|
|
||||||
|
|
||||||
Verified 120 functions available. Alembic migration `014_upgrade_pg_orrery_to_0_11_0` tracks the upgrade. Both local (`space.l.warehack.ing`) and production (`space.warehack.ing`) are running v0.11.0.
|
|
||||||
|
|
||||||
## 1. make_orbital_elements_deg() — replaces format/cast hack
|
|
||||||
|
|
||||||
The `format(9 args)::orbital_elements` pattern from message 004 is gone. Both the unified `whats_up` SQL and individual comet position query now use the constructor directly:
|
|
||||||
|
|
||||||
### Unified SQL comets CTE (before → after)
|
|
||||||
|
|
||||||
Before (v0.10.0):
|
|
||||||
```sql
|
|
||||||
LATERAL small_body_equatorial(
|
|
||||||
format('(%s,%s,%s,%s,%s,%s,%s,%s,%s)',
|
|
||||||
COALESCE(co.epoch_jd, co.perihelion_jd),
|
|
||||||
co.perihelion_au, co.eccentricity,
|
|
||||||
radians(co.inclination_deg),
|
|
||||||
radians(COALESCE(co.arg_perihelion_deg, 0)),
|
|
||||||
radians(COALESCE(co.lon_ascending_deg, 0)),
|
|
||||||
co.perihelion_jd,
|
|
||||||
COALESCE(co.magnitude_g, 0),
|
|
||||||
COALESCE(co.magnitude_k, 0)
|
|
||||||
)::orbital_elements,
|
|
||||||
NOW()
|
|
||||||
) AS eq
|
|
||||||
```
|
|
||||||
|
|
||||||
After (v0.11.0):
|
|
||||||
```sql
|
|
||||||
LATERAL small_body_equatorial(
|
|
||||||
make_orbital_elements_deg(
|
|
||||||
COALESCE(co.epoch_jd, co.perihelion_jd),
|
|
||||||
co.perihelion_au, co.eccentricity,
|
|
||||||
co.inclination_deg,
|
|
||||||
COALESCE(co.arg_perihelion_deg, 0),
|
|
||||||
COALESCE(co.lon_ascending_deg, 0),
|
|
||||||
co.perihelion_jd,
|
|
||||||
COALESCE(co.magnitude_g, 0),
|
|
||||||
COALESCE(co.magnitude_k, 0)
|
|
||||||
),
|
|
||||||
NOW()
|
|
||||||
) AS eq
|
|
||||||
```
|
|
||||||
|
|
||||||
Three classes of bugs eliminated:
|
|
||||||
1. **No `radians()` wrappers** — `_deg` variant handles conversion internally
|
|
||||||
2. **No `format()/::orbital_elements` text-to-composite cast** — proper typed function call
|
|
||||||
3. **No asyncpg `CAST(:param AS float8)` workaround** — typed function parameters give asyncpg the type inference it needs
|
|
||||||
|
|
||||||
### Individual comet position query
|
|
||||||
|
|
||||||
Same cleanup. Bind parameters are now direct float8 values without cast gymnastics:
|
|
||||||
|
|
||||||
```python
|
|
||||||
"epoch_jd": obj.epoch_jd or obj.perihelion_jd,
|
|
||||||
"q": obj.perihelion_au, "e": obj.eccentricity,
|
|
||||||
"i": obj.inclination_deg,
|
|
||||||
"w": obj.arg_perihelion_deg, "node": obj.lon_ascending_deg,
|
|
||||||
"g": obj.magnitude_g, "k": obj.magnitude_k,
|
|
||||||
```
|
|
||||||
|
|
||||||
## 2. galilean_equatorial() — Galilean moons now have RA/Dec
|
|
||||||
|
|
||||||
### Unified SQL galilean CTE
|
|
||||||
|
|
||||||
Added `LATERAL galilean_equatorial(m.id, NOW()) AS eq` alongside the existing `galilean_observe()`:
|
|
||||||
|
|
||||||
```sql
|
|
||||||
galilean AS (
|
|
||||||
SELECT m.name, 'planetary_moon' AS target_type,
|
|
||||||
('galilean_' || m.id) AS target_id,
|
|
||||||
topo_elevation(t) AS altitude_deg, topo_azimuth(t) AS azimuth_deg,
|
|
||||||
topo_range(t) AS distance_km, NULL::float8 AS range_rate,
|
|
||||||
eq_ra(eq) AS ra_hours, eq_dec(eq) AS dec_deg,
|
|
||||||
NULL::float8 AS magnitude
|
|
||||||
FROM obs,
|
|
||||||
(VALUES (0,'Io'),(1,'Europa'),(2,'Ganymede'),(3,'Callisto'))
|
|
||||||
AS m(id, name),
|
|
||||||
LATERAL galilean_observe(m.id, obs.o, NOW()) AS t,
|
|
||||||
LATERAL galilean_equatorial(m.id, NOW()) AS eq
|
|
||||||
WHERE topo_elevation(planet_observe(5, obs.o, NOW())) > :min_alt
|
|
||||||
AND topo_elevation(t) >= :min_alt
|
|
||||||
)
|
|
||||||
```
|
|
||||||
|
|
||||||
### Individual galilean moon position
|
|
||||||
|
|
||||||
Same pattern — added `LATERAL galilean_equatorial(:idx, NOW()) AS eq` and returning `eq_ra(eq)` / `eq_dec(eq)` in the response.
|
|
||||||
|
|
||||||
## Verification
|
|
||||||
|
|
||||||
### Comets — all 44 visible comets have RA/Dec
|
|
||||||
```
|
|
||||||
curl /api/sky/up?min_alt=0
|
|
||||||
-> 1083 objects, 44 comets, 0 with NULL RA/Dec
|
|
||||||
C/2025 K1-C: RA=1.5071h Dec=32.0202°
|
|
||||||
C/2025 K1 (ATLAS): RA=1.5045h Dec=32.0114°
|
|
||||||
P/2009 WX51: RA=1.8027h Dec=17.5734°
|
|
||||||
|
|
||||||
curl /api/targets/comet/840/position
|
|
||||||
-> 306P/LINEAR: RA=4.0122h Dec=29.4103° Alt=61.7° Az=93.9°
|
|
||||||
```
|
|
||||||
|
|
||||||
### Galilean moons — all 4 now have RA/Dec
|
|
||||||
```
|
|
||||||
curl /api/sky/up?min_alt=-90
|
|
||||||
-> Io: RA=7.1227h Dec=22.8745°
|
|
||||||
Europa: RA=7.1181h Dec=22.8822°
|
|
||||||
Ganymede: RA=7.1274h Dec=22.8656°
|
|
||||||
Callisto: RA=7.1319h Dec=22.8576°
|
|
||||||
|
|
||||||
curl /api/targets/planetary_moon/galilean_0/position
|
|
||||||
-> Io: RA=7.1227h Dec=22.8745° Alt=21.3° Az=76.6°
|
|
||||||
```
|
|
||||||
|
|
||||||
Cross-check: all 4 moons within 0.15° of Jupiter (RA≈7.12h Dec≈22.87°), consistent with your L1.2 regression vectors.
|
|
||||||
|
|
||||||
### Proximity query — moons appear near Jupiter
|
|
||||||
```
|
|
||||||
curl '/api/sky/near?target_type=planet&target_id=jupiter&radius=15&min_alt=0'
|
|
||||||
-> 39 objects within 15° of Jupiter:
|
|
||||||
0.02° - Io (planetary_moon)
|
|
||||||
0.05° - Europa (planetary_moon)
|
|
||||||
0.08° - Ganymede (planetary_moon)
|
|
||||||
0.15° - Callisto (planetary_moon)
|
|
||||||
0.54° - IUS R/B(1) (satellite)
|
|
||||||
3.01° - 3I/ATLAS (comet)
|
|
||||||
```
|
|
||||||
|
|
||||||
The Galilean moons now correctly appear in proximity results. Before v0.11.0, they had NULL RA/Dec and were excluded from proximity filtering.
|
|
||||||
|
|
||||||
### Production verified
|
|
||||||
```
|
|
||||||
Production (space.warehack.ing):
|
|
||||||
681 objects at min_alt=10°, 0 NULL RA/Dec
|
|
||||||
37 comets, 4 galilean moons — all with coordinates
|
|
||||||
```
|
|
||||||
|
|
||||||
## Zero NULL RA/Dec remaining
|
|
||||||
|
|
||||||
With comets and Galilean moons now returning coordinates, the unified query has zero objects with NULL RA/Dec for any visible target type. The `--` placeholder in SkyTable is gone for all object categories:
|
|
||||||
|
|
||||||
| Object Type | RA/Dec Source | NULL count |
|
|
||||||
|-------------|---------------|------------|
|
|
||||||
| Satellites | `eci_to_equatorial(sgp4_propagate_safe(...))` | 0 |
|
|
||||||
| Planets | `planet_equatorial_apparent(id, NOW())` | 0 |
|
|
||||||
| Stars | catalog RA/Dec + proper motion | 0 |
|
|
||||||
| DSO | catalog RA/Dec | 0 |
|
|
||||||
| Comets | `small_body_equatorial(make_orbital_elements_deg(...))` | 0 |
|
|
||||||
| Galilean moons | `galilean_equatorial(id, NOW())` | 0 |
|
|
||||||
|
|
||||||
## Files changed
|
|
||||||
|
|
||||||
| File | Change |
|
|
||||||
|------|--------|
|
|
||||||
| `packages/api/src/astrolock_api/services/sky_engine.py` | Replaced `format(...)::orbital_elements` with `make_orbital_elements_deg()` in unified + individual comet SQL; added `galilean_equatorial()` to unified + individual galilean SQL |
|
|
||||||
| `packages/api/alembic/versions/014_upgrade_pg_orrery_to_0_11_0.py` | New migration |
|
|
||||||
|
|
||||||
No schema changes. No new endpoints. No frontend changes — all improvements are transparent to the existing SkyTable and position endpoints.
|
|
||||||
|
|
||||||
## Ready to tag v0.11.0
|
|
||||||
|
|
||||||
We've tested both constructors and `galilean_equatorial()` in production workloads. Tag when ready.
|
|
||||||
|
|
||||||
## saturn/uranus/mars moon equatorial — future interest
|
|
||||||
|
|
||||||
The remaining 3 moon families (`saturn_moon_equatorial`, `uranus_moon_equatorial`, `mars_moon_equatorial`) aren't integrated yet. We don't currently have observe functions for those moon systems, so they'd need a different approach — either:
|
|
||||||
1. Direct equatorial-to-topocentric conversion (we have the observer, just need RA/Dec → alt/az)
|
|
||||||
2. Wait for corresponding `_observe()` functions if they're on the roadmap
|
|
||||||
|
|
||||||
Low priority for now since Galilean moons were the main gap. Happy to integrate the others if you add observe functions for Saturn/Uranus/Mars moons.
|
|
||||||

**Next steps for recipient:**
|
|
||||||
- [ ] Tag v0.11.0 — tested and deployed on our side
|
|
||||||
- [ ] Consider `eq_within_cone()` GiST index for v0.12.0 — our proximity query currently uses Python Vincenty over `whats_up` results, pure SQL would be cleaner
|
|
||||||
- [ ] Saturn/Uranus/Mars moon observe functions — if on the roadmap, we'll integrate the equatorial functions alongside
