SUPERNOVA 2010gz IN NGC 599
     S. Nakano, Sumoto, Japan, reports the discovery by Masaki Tsuboi
(Kuchita-minami, Asakita-ku, Hiroshima) of an apparent supernova (mag 16.0)
on a 30-s unfiltered CCD frame taken on Aug. 16.782 UT using a 0.30-m f/5.3
reflector; Tsuboi obtained confirming images (limiting mag 19.0) on Aug.
16.78 and 17.61 UT and measures the new object to be located at R.A. =
1h32m51s.07, Decl. = -12d11'21".5 (equinox 2000.0), which is 39".6 west and
6".7 north of the center of NGC 599.  Nothing is visible at this position on
Digitized Sky Survey red, blue, and infrared images (limiting mag 19 or
fainter).  The discovery image has been posted at the following website URL:
http://ytenku.hp.infoseek.co.jp/astrophoto/NGC599100817-01.jpg.  Nakano
measured mag 15.2 and position end figures 51s.05 +/- 0s.01, 21".7 +/- 0".2
for 2010gz from Tsuboi's FITS images
