Itagaki, Japan reports discovery of a previously unknown variable star on a wide-field survey CCD image taken on 2008 Dec. 16.420 UT with a 0.21-m f/3 reflector. Confirmation on Dec. 16.424 with a 0.60-m f/5.7 reflector showed the variable's magnitude to be about 15.4 and its position: RA 21h 31m 22.41s DEC -00 39' 36.8" (2000). It was fainter than mag 17.5 on 2007 Nov. 2.492, and fainter than mag 16.7 on 2008 Dec. 1.420. A faint blue star (magnitudes u = 21.6, g = 21.4, r = 21.4, i = 21.7, z = 21.2) in the Sloan Digital Sky Survey appears to be identical with the new variable. Hitoshi Yamaoka suggests that photometry by Maehara (Kyoto University) and A. Miyashita (Tokyo) indicate that this variable is a SU UMa-type dwarf nova.

Sand, Harvard-Smithsonian Center for Astrophysics and Las Cumbres Observatory Global Telescope Network et. al and located at: RA 02h 57m 26.41s DEC +12 58'07.6" (2000). Spectroscopic confirmation was obtained on Nov. 28 with GMOS-N on the Gemini telescope, showing 2008ih to be a type-Ia supernova at z = 0.061 and around 15 days past maximum SUPERNOVA 2008ii IN PGC 44965 Discovery by Berto Monard of a possible supernova (CBET 1625): SN 2008 UT R.A.
