Yasuda, University of Tokyo, on behalf of the Sloan Digital Sky Survey II collaboration, report the discovery of an apparent supernova on g, r, and i images taken with the SDSS 2.5-m telescope at Apache Point Observatory on Oct. 12 (discovery image; supernova at g = 18.5) and 14 (g approximately 18.0). SN 2005hc is located at R.A. = 1h56m47s.9, Decl. = -0o12'49".2, equinox 2000.0), which is approximately 9" west and 3".9 south of the center of MCG +00-6-3; a prior SDSS spectrum shows the host galaxy to be at redshift z = 0.0459. Fits to the two epochs of g-, r-, and i-band imaging suggest that 2005hc is a supernova of type Ia that is about 7 days before g maximum on Oct. 19 and that it will reach a peak magnitude of g around 17.
