title: NGC 4656 and NGC 4657
text: NGC 4656/57 is a highly warped barred spiral galaxy located in the constellation Canes Venatici and is sometimes informally called the Hockey Stick Galaxies or the Crowbar Galaxy. Its unusual shape is thought to be due to an interaction between NGC 4656, NGC 4631, and NGC 4627. The galaxy is a member of the NGC 4631 Group. A Luminous Blue Variable in "super-outburst" was discovered in NGC 4656/57 on March 21, 2005.
