Astronomy: Computed with astronomy-engine for these coordinates

Computed for 26.202° S, 28.044° E, elevation 1767 m, time zone Africa/Johannesburg. City centres are light-polluted; the times here apply anywhere within about 50 km, so drive out to darker skies.

Sun, Moon and planet positions are calculated with astronomy-engine. Twilight uses the Sun's geometric centre; sunrise and sunset use the upper limb with standard refraction.

The summary line restates the hourly total-cloud forecast inside the dark window (clear under 25%, cloudy from 65%) and the Moon's times. It is not a score — the Tonight score lives in the app.
