De Vaucouleurs Atlas Description:

The SDSS image reveals a well-defined, smooth spiral pattern which does not form an outer pseudoring and whose inner termination point lies well outside the bulge-dominated zone. The appearance suggests a weak oval might be present, but this feature is not clearly evident in blue light. The RC3 classification of (r) is incorrect; there is no inner ring.
