De Vaucouleurs Atlas Description:

In spite of the high inclination , this galaxy is easily recognized as being barred. However, due to significant foreshortening and heavy near-side extinction, the bar appears very weak. Short spiral arms break from near the bar ends and form only a very partial inner pseudoring . The near-side extinction severely impacts our view of the central region, but the nucleus is in the clear. There could be a central disk or bar. Beyond the bright inner zone, two faint outer arms form a weak outer pseudoring . This image is from Frei et al. (1996) and has had foreground stars removed.
