Supernova in UGC 10936

Supernova in UGC 10936



Tim Puckett and his team was just awarded a supernova discovery in a small (2'), faint (mag 17) galaxy, UGC 10936 in Draco. The seeing at the SRO site at 1400 m elevation was near 1" and the full moon was out for this LRGB image. Tim asked us if we would like to image this object. The IAU text is shown below. SUPERNOVA 2008an IN UGC 10936 J. Newton, Portal, AZ, U.S.A; and T. Puckett, Ellijay, GA, U.S.A., report the discovery of an apparent supernova (mag 17.3) on unfiltered CCD images (limiting mag 19.7) taken with a 0.40-m reflector at Portal, AZ, on Feb. 24.52 UT in the course of the Puckett Observatory Supernova Search. The new object was confirmed at mag 17.2 on co-added images (limiting mag 19.1) taken by T. Orff on Feb. 25.48 with a 0.40-m reflector at Portal, AZ. SN 2008an is located at R.A. = 17h38m28s.18, Decl. = +61o02'13".7 (equinox 2000.0), which is 4".9 east and 9".8 south of the center of UGC 10936. Nothing is visible at this position on images taken by Puckett on 2007 May 23 (limiting mag 19.0).

Green Paul provided an older dss plate of this object and I used Registar to register both images and create an animiated GIF. To place this object in perspective, the full field-of-view image is shown below:
