Rozhen Night Plan

Up to ten targets, one night: each gets its good/marginal/poor windows (darkness × altitude × Moon × clouds, as on the single-target page), then the night is handed out five minutes at a time to whichever target is best — with hysteresis, so you get a few solid blocks of at least 30 minutes, not a flicker. Targets that never win a block are listed with the reason.

Night of Wednesday, 09 March 2033 · astronomical night 19:53 → 05:08 (9.26 h) · Moon 69% (waxing gibbous) · weather: none — the schedule is astronomy only; overall conditions unknown

curl -sS "https://devops.majbase.com/rozhen-planner/plan-api?targets=M31,M42,M45,NGC%207000&date=2033-03-09"

targets: names or RA Dec, separated by commas, semicolons or newlines, at most ten. The response carries targets[] (score, verdict, best_window, windows, transit, moon_separation), schedule[] (blocks with target, start/end in UTC and local, hours, mean_quality; target: null is idle time), unscheduled[] with a why, forecast_source, warnings[]. Missing targets → 400 {"error", "code": "targets_missing"}; an unreadable date → 400 {"error", "code": "invalid_date"}.
