The object, located about 10.0" west and 8.0" north of the centre of the host galaxy had been recorded using unfiltered CCD images with a 0.35-m Schmidt-Cassegrain telescope. The measured position is: RA 16h 27m 21.27s DEC +39 06' 43.2" (2000) The suspect is not present on Tom's images of 2004 May 27 and Aug 06 (limiting mag 19.5) and it is not present on DSS II red (1993.327 limiting mag 20.5) nor blue plates (1989.412 limiting mag 20.5) A further e-mail received on April 12 indicated confirmation had been obtained on April 12.004UT. The object has been designated supernova and announced on IAUC 8511. Congratulations to Tom on the discovery of his 88th supernova. SUPERNOVA 2005bg IN MCG +03-31-93 Discovery by R. Quimby et. al, McDonald Observatory, of a possible supernova (IAUC 8508): SN 2005 UT R.A. (2000.0) Decl. Mag. Offset 2005bg Mar. 28.17 12 17 17.18 +16 22 17.6 16.2 0.6"N, 0.4"E A spectrum suggests this is of type Ia. SUPERNOVA 2005bh IN UGC 6495 Discovery by T. Puckett and L. Cox of a possible supernova (IAUC 8509): SN 2005 UT R.A. (2000.0) Decl. Mag. Offset 2005bh Apr. 10.10 11 29 44.00 +22 07 39.1 17.3 16.7"W, 3.7"N SUPERNOVA 2005bd IN MCG +09-11-2 The discovery of this supernova by Tom Boles was reported on TA E-Circular 2105. According to IAUC 8508, a spectrum obtained by H. Landt on 2005 April 9.15UT with the F. L. Whipple Observatory 1.5-m telescope indicates it to be of type-Ia, then about 8 days past maximum.
