SUPERNOVA 2001gc IN UGC 3375

M. Schwartz, Cottage Grove, OR; and W. D. Li, University of California at Berkeley, on behalf of LOTOSS (cf. IAUC 7514), report the discovery of an apparent supernova on an unfiltered image taken with the 0.5-m Tenagra III automated telescope on Nov. 21.4 UT (mag about 16.2). SN 2001gc is confirmed at mag about 16.8 on an earlier image taken by the Katzman Automatic Imaging Telescope under poor conditions on Nov. 19.5. The new object is located at R.A. = 5h55m26s.14, Decl. = +51o54'34".2 (equinox 2000.0), which is 7".3 east and 4".3 south of the nucleus of UGC 3375. A Tenagra III image taken on Nov. 14.4 showed nothing at this position (limiting mag about 19.0).
