Barred Spiral Galaxy NGC 5698:

Barred Spiral Galaxy NGC 5698 lies in the Constellation of Bootes. It has a small but bright nucleus and dark patches east and west of the nucleus. The two spiral arms start at the end of the bar and each sweep nearly 180 degrees around the galaxy.

Dreyer description in the New General Catalog(NGC):

"Considerably faint, considerably small, little extended, in triangle of stars".

Based on the published red shift, (and a Hubble Constant of 62 Km/sec per Mpc) a rough distance estimate for NGC 5698 and SN 2005bc is 193 million light years, with a galaxy diameter of about 107,000 light years.
