De Vaucouleurs Atlas Description:

The discordant classifications between RC3 and SB94 are due to the unusual morphology of this galaxy. The main section appears like a highly inclined Sb spiral with significant near-side extinction and strange dust lanes projected against the far side. The core is very small and is surrounded by a few bright knots. These knots are part of a significant nuclear starburst . Most unusual is the structure outside the bright inner zone. Connecting to this zone is a large, faint outer ring that is easily recognized as OLR subclass R₁ (seen best in the deprojected V-band image.) Thus, the apparent Sb zone is a bar-like oval. The perpendicular dust lanes in this oval have been interpreted in terms of outflow (Phillips 1993). The central starburst is discussed by Krabbe, Sternberg, and Genzel (1994) and Aalto et al. (1994).
