SUPERNOVA 2001ez IN PGC 17642

D. J. Hutchings and W. D. Li, University of California at Berkeley (UCB), report the discovery by LOTOSS (cf. IAUC 7514) of an apparent supernova in unfiltered images taken with the Katzman Automatic Imaging Telescope on Oct. 17.5 (mag about 17.8) and 18.5 UT (mag about 17.6). SN 2001ez is located at R.A. = 5h42m37s.64, Decl. = +69o14'14".6 (equinox 2000.0), which is 3".3 east and 2".0 north of the nucleus of PGC 17642. A KAIT image taken on Oct. 2.5 shows nothing at this position (limiting mag about 19.5).
