Fallstreak Holes

On the Web

On Wikipedia

A fallstreak hole (also known as a cavum, hole punch cloud, punch hole cloud, skypunch, cloud canal or cloud hole) is a large gap, usually circular or elliptical, that can appear in cirrocumulus or altocumulus clouds. Because of their rarity and unusual appearance, fallstreak holes have been mistaken for or attributed to unidentified flying objects.
