He noted it was absent from his images of 2000 Nov 24, 2002 Jan 17, Feb 15 and Mar 1. A check of Palomar Sky Survey images of 1996 June 19 (blue, limit 22.5) and 1998 Jan 2 (red, limit 20.8) also did not show it. No movement had been detected in a 3.7 hour period for this magnitude 17.1 object located 5" north and 5" east of the galaxy's nucleus. The measured position was: RA 10h 34m 08.92s DEC +19 42' 20.5"(2000). Following the issue of an alert to the TA Checking Group, Tom Boles successfully imaged the object with a 0.35-m Schmidt-Cassegrain telescope and unfiltered CCD on March 13.843UT at magnitude 17. IAUC 7853 was issued with the designation 2002br. Again our congratulations to Mark on this further success. SUPERNOVA 2002bq in MCG -06-21-10 Berto Monard of South Africa has reported his detection of a possible magnitude 16.1 supernova on three CCD images (no filter) taken with a 0.30-m reflector on March 9. The location is: RA 09h 30m 50.92s DEC -35 42' 06.0" (2000). 35"W and 46"S of the nucleus of MCG -06-21-10. Further details have appeared on IAUC 7848. SUPERNOVA 2002bn IN UGC 6527 This object discovered by Mark Armstrong and announced on TA E- Circular 1751 has been spectroscopically confirmed by Tom Matheson et.al., Harvard Smithsonian Center for Astrophysics, who report on IAUC 7851 that it is of type-Ia.
