De Vaucouleurs Atlas Description:
The bar seems well-defined in this late-type spiral, but it is fairly weak. Surrounding the bar, a clear patchy inner ring of low contrast is found, unusually complete for such a late Hubble type. Both the ring and the bar are much more comspicuous in a 2.2 micron image (Mollenhoff and Heidt 2001).
Much of the outer spiral structure in the B-band image is as ill-defined as the inner ring , partly because of the high surface brightness of the background disk light. At least two main spiral arms and a host of weaker features are present outside the inner ring.
