Image taken with an ST-9E CCD camera thru Kopernik's 20 inch F/8.1 telescope. A 15 minute exposure taken at 5:05 UT on May 19, 2003. The field of view is 8x8 arc minutes with North at the top.

Supernova 2003 dw:

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 10548:

This 14.5 magnitude barred spiral galaxy is in the constellation of Draco. There are two long smooth spiral arms extending from the end of the bar. They are very faint and nearly form a complete ring before continuing for another 180 degrees around the bar.

Based on the published red shift, (and a Hubble Constant of 62 Km/sec per Mpc) a rough distance estimate for UGC 10548 and SN 2003dw is 474 million light years, with a galaxy diameter of about 207,000 light years.
