As of today, out of season. Earth Exhibit tracks the live conditions and flags it the moment it is on.
A fogbow, sometimes called a white rainbow, cloudbow or mistbow, is an arc formed by sunlight or moonlight interacting with very small water droplets in fog or low cloud.
Because the droplets are tiny, diffraction smears the colors and the bow appears broad and mostly white, with only faint red (outer) and blue (inner) fringes under ideal conditions.
