The Sunflower Galaxy (M63, NGC 5055) is a spiral galaxy (type Sb or Sc) in Canes Venatici that appears to lie in the M51 Group dominated by the Whirlpool Galaxy (M51); it was discovered in 1779 by Pierre M�chain. The Sunflower's spiral arms show up as a grainy background, which brightens slowly at first, going in from the periphery, but then rapidly to the nuclear region. It hosted a Type I supernova (1971I), first seen on May 25, 1971, which reached magnitude 11.8.
