Williams M.P.E.C. 1999-U37 SUPERNOVA 1999ej IN NGC 495 A. Friedman, J. Y. King, and W. D. Li, University of California at Berkeley (UCB), report the discovery by the Lick Observatory Supernova Search with the 0.8-m Katzman Automatic Imaging Telescope (KAIT) of an apparent supernova in NGC 495. SN 1999ej was discovered and confirmed on unfiltered images taken on Oct. 18.3 and 19.3 UT (both with mag about 18.1). The new object is located R.A. = 1h22m57s.38, Decl. = +33o27'58".0 (2000), which is 17".7 east and 20".1 south of the nucleus of NGC 495. IAUC 7286 SUPERNOVA 1999ek in UGC 3329 R. Johnson and W. D. Li, UCB, also report the discovery by the LOSS with the KAIT of an apparent supernova in UGC 3329. SN 1999ek was discovered and confirmed on unfiltered images taken on Oct. 20.5 (mag about 18.1) and 21.4 UT (mag about 17.9). The new object is located at R.A. = 5h36m31s.60, Decl. = +16o38'17".8 (2000.0), which is 11".7 west and 12".1 south of the nucleus of UGC 3329. Guy M Hurst
