Dear SN watchers, The CfA team have taken spectra of two recent SNe on May 22. They can be seen at: http://cfa-www.harvard.edu/cfa/oir/Research/supernova/RecentSN.html SN 2003ej: In [vsnet-campaign-sn 624] (May 22): >SN2003ej 20030511.3 <185:C KAI >SN2003ej 20030520.3 165:C KAI >SN2003ej 20030521.3 163:C KAI > ># SN 2003ej (12:39:11.10, +0:43:30.4 (J2000.0), offset = 4"W, 28"N) is ># hosted by UGC 7820, a face-on spiral (SAB(s)cd:) galaxy. It is ># superimposed on the outermost arm region. The expected maximum for ># typical SN Ia is mag about 15.9. It turned out to be a young type II SN. The observer notes that it can resemble the SN IIb 1993J. SN 2003ek: In [vsnet-campaign-sn 624] (May 22): >SN2003ek 20030512.5 <190:C KAI >SN2003ek 20030520.5 182:C KAI >SN2003ek 20030521.3 182:C KAI > ># SN 2003ek (17:18:32.50, +41:40:00.8 (J2000.0), offset = 4"E, 5"S) is ># hosted by FGC 2126, an edge-on spiral (Sc) galaxy. It lies between ># a lenticular (S0) galaxy NGC 6350 (mag 14.17, v_r = 9769 km/s) and a ># spiral (Sb) galaxy NGC 6348 (mag 15.6, v_r =1924 km/s). The ># relation between the magnitudes and the recession velocities of ># these two seems somewhat queer. FGC 2126 itself is dimmer than ># these two, and the expected maximum for typical SN Ia is mag around ># 17.5. It turned out to be somewhat reddened SN Ia before maximum. The recession velosities of these two on the NED seem to be correct, so are the expected typical unreddened SN Ia maxima. Sincerely, Hitoshi
