De Vaucouleurs Atlas Description:

The bar is well-defined with leading dust lanes. A trace of an inner pseudoring is present, but it is not sufficiently closed to merit the RC3 variety of (r). The outer spiral pattern includes at least four main arms. Faint spiral structure is present outside the bright inner spiral zone.
