= Subsun
{wiki=Subsun}
"Subsun" generally refers to a phenomenon related to atmospheric optics, particularly involving the appearance of a bright spot on the ground or water surface beneath a cloud. This occurs when sunlight shines through a gap in the clouds, creating a concentrated beam of light that illuminates a specific area below, often surrounded by shadow. Subsun can also be used to describe similar optical effects, such as those involving halos or other light phenomena.
