- It uses hourly cloud cover during the viewing window and requires the galactic core to reach roughly 15° altitude.
Field notes
The methodology accounts for the galactic core’s coordinates and altitude, astronomical twilight, lunar altitude and illumination, and local light pollution. The page distinguishes Bortle 1–3 skies from brighter conditions and says Bortle 7 and above makes the Milky Way effectively invisible. It also links to methodology, data sources, and guides on seasonality and moonlight.
