Supernova 2011fh in NGC 4806.


Abstract (from CDS):

L. A. G. Monard, Calitzdorp, Western Cape, South Africa, reports his discovery of an apparent supernova (mag 14.5) on unfiltered CCD images taken on Aug. 24.746 and 25.716 UT at the Klein Karoo Observatory. The new object is located at R.A. = 12:56:14.01, Decl. = -29:29:54.8 (equinox 2000.0), which is 14" east and 21" north of the core of the galaxy NGC 4806; this position coincides closely with a dense region of the galaxy that has a starlike appearance (as seen on a red Digitized Sky Survey image). Photometric measurements on archived images taken at the Klein Karoo Observatory on several occasions in 2011 showed a brightening of this region starting around 2011 Feb. 11.190 (mag 17.0) and gradually brightening to mag 16.4 around June 2.812 and to mag 16.0 on Aug. 2.710 (which was the last observation prior to the discovery on Aug. 24).
