Spiral Galaxy NGC 6616 and Supernova 2002 dk
CCD image taken with an ST-9E CCD camera thru Kopernik's 20 inch F/8.1 telescope at 4:35 UT on July 11th, 2002. This was a 10 minute exposure. The field of view is 8x8 arc minutes with North at the top.

Supernova 2002 dk:

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 NGC 6616:

NGC 6616 is an edge-on spiral galaxy in the constellation of Hercules. Note the two background galaxies in the image:

"G1" = 2MASXi J1817318+221453 and "G2" = 2MASXi J1817301+221140

Quote from The Deep Sky Field Guide to Uranometria 2000:

"Strong absorption lane across nuclear region; Companion galaxy at 2.2 arc minutes, 287 degrees, size = 0.4 x 0.2 arc min."

Based on the published red shift, (and a Hubble Constant of 62 Km/sec per Mpc) a rough distance estimate for NGC 6616 and supernova 2002 dk is 292 million light years.
