Sunflower Galaxy (M63, NGC 5055)
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 Méchain.
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.
