Dear SN watchers, IAUC 8170 informed the classifications of three recent SNe. SN 2003gn: In [vsnet-campaign-sn 659] (Jul. 24): >SN2003gn 20030710.4 <190:C KAI >SN2003gn 20030719.0 <180:C KAI >SN2003gn 20030722.4 184:C KAI >SN2003gn 20030723.4 181:C KAI > ># SN 2003gn (22:33:51.68, +20:48:08.5 (J2000.0), offset = 16"E, 11"S) ># is hosted by an apparent spiral galaxy CGCG 452-024. The expected ># maximum for typical SN Ia is mag about 17.5. The UCB group (Jul. 27 UT) and the CfA group (Jul. 29.37 UT) show that it is type Ia SN near maximum. SN 2003gp: In [vsnet-campaign-sn 660] (Jul. 27): >SN2003gp 20030716.2 <190:C KAI >SN2003gp 20030723.2 186:C KAI >SN2003gp 20030725.2 186:C KAI > ># SN 2003gp (16:03:55.47, +25:00:24.8 (J2000.0), offset = 13"E, 12"S) ># is hosted by UGC 10160, a barred-spiral (SBa) galaxy. The expected ># maximum for typical SN Ia is mag about 17.5. The UCB group (Jul. 27) confirm that it is a young type II SN. SN 2003gq: In [vsnet-campaign-sn 660] (Jul. 27): >SN2003gq 20030708.0 <200:C Puc >SN2003gq 20030724.32 176C Puc > ># SN 2003gq (22:53:20.68, +32:07:57.6 (J2000.0), offset = 5"W, 11"N) ># is hosted by NGC 7407, a spiral (Sbc) galaxy. The maximum for ># typical SN Ia is mag about 16.5. Odd Trondal's observation (CRmag = ># 16.3 on Jul. 27.001) suggests that this SN is of this type. The UCB team (Jul. 27) also show that it is type Ia SN near or slightly before maximum; they quote that it resembles that of peculiar (bright) SN Ia 1991T.
