How we score the sky
80–100 · Excellent
60–79 · Good
40–59 · Marginal
0–39 · Poor
Scores combine cloud cover (weighted heaviest), humidity, wind, visibility, and moon illumination during dark hours. Astronomical darkness is calculated from the sun's altitude (< −18°). Moon impact only counts when the moon is above the horizon after dusk.
