The intensity of moonlight varies greatly depending on its phase, but even the full Moon typically provides only about 0. 05–0. 1 lux illumination. When the full Moon is at perigee and viewed around upper culmination from the tropics, the illuminance can reach up to 0. 32 lux. From Earth, the apparent magnitude of the full Moon is only about 1⁄380,000 that of the Sun.
