SUPERNOVA 2002db IN NGC 5683

B. Beutler and W. D. Li, University of California at Berkeley, for the LOTOSS team (whose core members are Li, A. V. Filippenko, R. R. Treffers, and M. Schwartz, as of 2001 Sept. 1; see also IAUC 7514), report the discovery of an apparent supernova on an unfiltered CCD image taken with the 0.8-m Katzman Automatic Imaging Telescope (KAIT) on May 18.3 UT (mag about 17.6). The new object was confirmed on an image taken with the 0.6-m telescope at Beijing Astronomical Observatory by Y. L. Qiu and W. Zhou under poor conditions on May 20.6. SN 2002db is located at R.A. = 14h34m51s.63, Decl. = +48o39'52".9 (equinox 2000.0), which is 8".0 west and 9".3 north of the nucleus of NGC 5683. A KAIT image taken on May 10.3 showed nothing at this position (limiting mag about 19.0).
