Examples of a Brocken Spectre, a phenomenon where a person’s giant shadow appears magnified onto clouds miles away. The shadow from the sun behind the person creates a halo, giving it an angelic appearance. This mostly occurs on any misty mountainsides or cloud banks, and can even be seen from aeroplanes.
Iridescent clouds, looking like a rainbow in the clouds.
A diffraction phenomenon caused by small water droplets or small ice crystals individually scattering light. Larger ice crystals do not produce iridescence, but can cause halos, a different phenomenon.
