SUPERNOVA 2001M IN NGC 3240

A. B. Aazami and W. D. Li, University of California at Berkeley, on behalf of LOTOSS (cf. IAUC 7514), report the discovery with the 0.8-m Katzman Automatic Imaging Telescope (KAIT) of an apparent supernova on unfiltered images taken on Jan. 21.4 (mag about 17.5) and 22.4 UT (mag about 17.7). SN 2001M is located at R.A. = 10h24m31s.48, Decl. = -21o47'40".6 (equinox 2000.0), which is 12".3 east and 12".7 south of the nucleus of NGC 3240. A KAIT image of the same field taken on Jan. 3.4 showed nothing at this position (limiting mag about 19.0).
