Dear SN watchers, The UCB team reported classifications of several SNe on IAUC 8189. All spectra are taken on Aug. 28 UT with Shane 3-m telescope at Lick Observatory. SN 2003hj: In [vsnet-campaign-sn 674] (Aug. 21): >SN2003hj 20030528.0 <195C Bol >SN2003hj 20030819.92 175C Bol >SN2003hj 20030820.846 179C Bol > ># SN 2003hj (15:24:20.51, +29:57:11.9 (J2000.0), offset = 1"E, 8"S) is ># hosted by MCG +05-36-28, a dim galaxy. The expected maximum for ># typical SN Ia is mag about 19, so further photometry and spectral ># type determination (or the redshift of the host galaxy) is urged. It is SN Ia 2 weeks after maximum. The recession velocity of the host galaxy was measured as v_r = 23000 km/s. The observed brightness is quite bright.
