A U.S. Coast Guard HH-65C Dolphin rescue helicopter from Coast Guard Air Station Atlantic City flies near a circumhorizontal arc, an atmospheric phenomenon sometimes called a "fire rainbow" on Nov. 6 at Atlantic City International Aiport, N.J. The circumhorizontal arc is formed by plate-shaped ice crystals in high level cirrus clouds.
