Image taken with an ST-9E CCD camera thru Kopernik's 20 inch F/8.1 telescope. Image taken under poor seeing conditions at 3:15 UT on May 19, 2003. The field of view is 8x8 arc minutes with North at the top.
Supernova 2003 du:
Follow this Link to a NASA Web site on supernovas. It has a very nice animation and a description of what these objects are.
Spiral Galaxy UGC 9391:
This 15.0 magnitude galaxy is in the constellation of Draco. It is a face-on spiral galaxy that is relatively dim and has a low surface brightness. Unfortunately, because of the poor seeing conditions, the Kopernik image above does not show the structure of the arms.
Based on the published red shift, (and a Hubble Constant of 62 Km/sec per Mpc) a rough distance estimate for UGC 9391 and SN 2003 du is 100 million light years, with a galaxy diameter of about 50,000 light years.
