Abstract: R. Arbour, South Wonston, Hampshire, England, reports his discovery of an apparent supernova (mag 16.3) on an unfiltered CCD image taken on Dec. 17.952 UT using a 0.3-m f/6.3 reflector. SN 2002jy is located at R.A. = 1h21m16s.27, Decl. = +40o29'55".3 (equinox 2000.0), which is 46".4 west and 37".6 north of the center of the galaxy NGC 477. Nothing is present at this location on a 1995 blue Palomar Sky Survey plate (Digital Sky Survey). Further images taken by Arbour on Dec. 18.713 and 18.719 show the new object at about the same brightness, and an unfiltered CCD image taken by T. Boles, Coddenham, Suffolk, England, on Dec. 18.731 yields mag 16.5 and position end figures 16s.23, 55".6. T. Vanmunster, Landen, Belgium, reports his independent discovery of SN 2002jy (providing position end figures 16s.26, 55".5) on unfiltered CCD images taken on Dec. 18.96 with a 0.35-m f/6.3 telescope during an automated supernova-search program; a confirming CCD image was obtained on Dec. 18.991 by P. Van Cauteren and P. Lampens at Beersel, Belgium, yielding V = 16.0 for the new object. SN 2002jy was not visible on Vanmunster's CCD image taken on Oct. 11.075 (limiting unfiltered mag 17.2) or on 1977 red Digitized Sky Survey images (limiting mag 19.5).
