The object was first recorded on a 30 second unfiltered CCD image of October 3.882UT (limiting magnitude 18.5) obtained with a 0.35-m Schmidt-Cassegrain and was subsequently recorded on multiple images over a six hour period but on a single night. He derived a position: RA 01h 55m 46.55s DEC +46 48' 19.1" (2000) Although the fast Near Earth Object 1998 UO1 was 11' away this was not the candidate. Confirmation was then obtained with the 0.35-m telescope in a 60 second integration of October 4.845UT with end figures: RA 46.53s DEC 19.4" (2000). The magnitude was then R=17.3. Offsets from UGC 1394 are: 11.9"N and 44.3"E. The object was not present on Tom's images of 2001 Sept 3 (limiting magnitude 19.0), 2002 August 12 or July 15. It was also not detected on red and blue plates of the second Palomar Sky Survey. The designation of SN 2002gc was announced on IAUC 7983. Our congratulations to Tom on this further success. SUPERNOVAE 2002fv, 2002fw, 2002fx, 2002fy, 2002fz, 2002ga M. Giavalisco et.al., of the Space Telescope Science Institute on behalf of various search teams have reported the discovery of six supernovae designated as above. All are of magnitude 24 or fainter and were discovered between 2002 Sept 19 and 22 in anonymous galaxies. Further details appear on IAUC 7981. SUPERNOVA 2002gb IN ANONYMOUS GALAXY W. M. Wood-Vasey has reported on IAUC 7983 that a supernova has been found on Palomar NEAT images of 2002 August 28.26UT in an anonymous galaxy. The position of the magnitude 18.9 object is: RA 22h 43m 21.31s DEC -00 06'53.0" (2000), 1.4"S of the nucleus. Guy M Hurst
