Sky now

Zenith at the centre, horizon at the rim. North is up and east is to the right, so the disc reads like a map of the ground rather than a star chart.

The dashed line is 20° from the moon. It is not a circle: a fixed angular separation projects to a distorted shape, so it is drawn from the real locus.

Flat red is discouraged, never excluded — the north is avoided for Trieste’s light dome, not because anything blocks it, so targets there are still listed and still plotted.

Hatched red is different. That sky risks damaging the mount, so it is a hard limit: targets there are removed from the queue and the plan file, and no marker is drawn, for as long as they are inside it. Nothing can override it.

W 247.5–292.5° 40° warned observer: West = 40°
NW 292.5–337.5° 40° warned observer: Northwest = 40°

The mask warns; it does not remove. Every sector is currently soft, so a target in poor sky stays in the queue carrying a badge. The north is avoided because Trieste sits 41 km away at bearing 3° and lights that sky, not because anything obstructs it — and an impactor found in the north has to appear on this board. Each sector says why above, which is what tells you whether a limit is safe to relax; mark one hard (settings) only once it is confirmed as a physical obstruction. The observatory's own planner has no azimuth mask at all, only a flat altitude floor.

Azimuths are compass bearings from north. MPC reports azimuth from south; it is converted on parse and verified against an independent astropy calculation every cycle. That convention was confirmed against 579 ephemeris lines of the observatory's own output — read as compass, five of 579 targets fall in the north; read raw, north would be the busiest sector on the sky.

Shoot is 36 frames for every target, with the frame length set by how fast the object is moving at its best altitude — the observatory's own table: ≤5″/min → 30s, ≤25″/min → 15s, ≤50″/min → 10s, ≤100″/min → 5s, ≤200″/min → 2s, faster → 1s.

The plan file also still carries obsExposure, the legacy figure from planets-new.py: total integration in minutes from magnitude alone, 10 + (V − 18) × 5, floored at 1 (unfloored it goes negative for bright targets, and the observatory's own files contain obsExposure=-2.0min). It ignores sky motion entirely, so it will not agree with Shoot — a slow target is 36×30s = 18 minutes on sky against an obsExposure nearer 27. Shoot is the instruction.

Still open: which sectors, if any, are real obstructions rather than preferences. Also SW, never specified and interpolated to 30°; NW, given as both 50° and 40°; W, as both “30–40” and 40°; and an upper elevation limit mentioned but never valued.
