Serene Paraselene
Explanation: Nestled in the Austrian Alps, frozen Lake Ossiach stretches across the foreground of this serene view. Recorded on March 1, the night sky includes a nearly full Moon and bright planet Saturn seen through thin clouds near picture center. It also includes a remarkably bright and colorful moondog or paraselene at the left. Analogous to a sundog or parhelion , the paraselene is produced by moonlight shining through thin, hexagonal-shaped ice crystals in high cirrus clouds . As determined by the ice crystal geometry, the Moon is 22 degrees from the lovely paraselene.
