Dear SN watchers, IAUC 8225 informed the classifications of the recent three SNe by the CfA group. The spectra can be seen at: http://cfa-www.harvard.edu/cfa/oir/Research/supernova/RecentSN.html . SN 2003io: In [vsnet-campaign-sn 704] (Oct. 3): >SN2003io 20000107.0 <200:C Puc >SN2003io 20030930.27 171C Puc > ># SN 2003io (2:17:26.87, +14:34:36.3 (J2000.0), offset = 11"E, 13"S) ># is hosted by UGC 1761, an irregular (Im) galaxy within a small group ># of galaxies. The expected maximum for typical SN Ia is mag about ># 15.5. It is a type II SN. SN 2003iq: In [vsnet-campaign-sn 705] (Oct. 9): >SN2003iq 20031005.97 <175:CR LLA >SN2003iq 20031008.958 164:CR LLA >SN2003iq 20031009.60 160:R BiS > >observers: BiS: Bisei Astronomical Observatory > ># SN 2003iq (1:59:19.92, +17:59:41.8 (J2000.0), offset = 5"E, 46"S) ># appears in the same spiral (SA(s)b) galaxy NGC 772 as SN 2003hl. ># At the discovery, the new object is slightly brighter than SN ># 2003hl. The expected maximum for typical SN Ia in this galaxy ># is mag about 14.7. Further observation and spectral classification ># is urged. It is also a type II SN, with a very blue continuum (a young SN) and relatively strong He line. SN 2003is: In [vsnet-campaign-sn 707] (Oct. 16): >SN2003is 20031004.1 <195:C KAI >SN2003is 20031014.1 180:C KAI >SN2003is 20031015.1 180:C KAI > ># SN 2003is (19:21:08.00, +43:19:35.4 (J2000.0), offset = 4"W, 4"N) is ># hosted by MCG +07-40-3 = UGC 11430, a face-on spiral (SA(s)c galaxy. ># Because of a low Galactic latitude (b = 13o), there are many ># foreground stars around MCG +07-40-3; a mag 14 star is located about ># 25" NE of the center of the galaxy. The expected maximum for ># typical SN Ia is mag about 16.3. It is a type Ic SN, probably somewhat (a few days) before maximum light on Oct. 16.18 UT.
