Alpenglow
Alpenglow (from German: Alpenglühen, Italian: Enrosadira) is an optical phenomenon that appears as a horizontal reddish glow near the horizon opposite of the Sun, when the solar disk is just below the horizon.
This effect is easily visible when mountains are illuminated, but can also be seen when clouds are lit through backscatter.
Since the Sun is below the horizon, there is no direct path for the sunlight to reach the mountain.
Unlike sunrise or sunset, the light that causes alpenglow is reflected off airborne precipitation, ice crystals, or particulates in the lower atmosphere. These conditions differentiate between a normal sunrise or sunset and alpenglow.
True alpenglow is not direct sunlight and is only visible after sunset or before sunrise.
