Green rays or green flashes are an optical phenomenon that is sometimes observed for several seconds after sunset or before sunrise, when the appropriate conditions for observation are met. A green spot appears on the upper edge of the sun’s disk, and it may appear in the form of a green ray emanating from the sun’s disk at the sunset point.
Sometimes, when the air is particularly pure, a sufficient amount of blue or violet light rays pass through the atmosphere and produce a blue flash instead of a green flash. However, green is the most common color captured in photos.
