M63 is a class SB spiral galaxy in Coma Berenices lying at a distance of 23.9 million light years. Unlike grand design SB spiral galaxies with well-defined spiral arms, M63 is of the rarer "floculent" design with spiral arms that cannot be traced. This design has the characteristic of having a sharp drop off in brightness between the core and the spiral arms, making it difficult for imagers to display both features simultaneously. The sigmoid whisp below the bright star to the right side of the galaxy is irregular galaxy UCGA 342, which appears to be a satellite galaxy of m63, analogous to one of our Magellanic Clouds.
