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. (U.S. Air National Guard photo by Tech. Sgt. Matt Hecht/Released)
