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 Saturday, 19 December 2026 · astronomical night 18:33 → 06:03 (11.51 h) · Moon 77% (waxing gibbous) · weather: none — the schedule is astronomy only; overall conditions unknown
Each row is the target's quality through the night, white → amber → green for 0 → 0.3 → 0.6 → 1 (the same thresholds as poor / marginal / good). Dark blue: the schedule. Grey columns: twilight. Download: schedule CSV · targets CSV · JSON
