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. 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. SN 2003ef: In [vsnet-campaign-sn 620] (May 12): >SN2003ef 20030322.3 <185:C KAI >SN2003ef 20030511.3 163:C KAI > ># SN 2003ef (12:49:42.25, -11:05:29.5 (J2000.0), offset = 12"E, 5"N) ># is hosted by NGC 4708, a spiral (SA(r)ab pec?) galaxy. The expected ># maximum of typical SN Ia is mag about 15.5. Note that a faint ># galaxy is superimposed on the northwest part of NGC 4708. The CfA team has revealed that it is type II SN by a spectrum taken on May 21.19 UT. SN 2003eg: In [vsnet-campaign-sn 622] (May 19): >SN2003eg 20030414.3 <185:C KAI >SN2003eg 20030517.3 158:C KAI >SN2003eg 20030518.3 158:C KAI > ># SN 2003eg (12:50:58.33, -14:20:01.1 (J2000.0), offset = 16"E, 3"S) ># is hosted by NGC 4727, a spiral (SAB(r)bc pec:) galaxy making a ># close pair with NGC 4724 (about 1' west of NGC 4727).

The ># expected maximum for typical SN Ia in this group is mag about 15.5. ># The spectral classification of the SN and the determination of the ># recession velocity is important. The CfA team also took a spectrum of SN 2003eg on May 21.21 UT, which shows that it is type II SN sooon after explosion. The recession velocity of the host galaxy was measured as 4360 km/s, which resolved above suspicion. It is somewhat luminous event as a gravitational collapse. SN 2003eh: In [vsnet-campaign-sn 622] (May 19): >SN2003eh 20030501.2 <185:C KAI >SN2003eh 20030517.2 176:C KAI >SN2003eh 20030518.3 176:C KAI > ># SN 2003eh (11:08:24.34, +3:29:47.0 (J2000.0), offset = 6"E, 6"S) is ># hosted by MCG +01-29-3, a barred-spiral (SB(s)b:) galaxy. The ># expected maximum for typical SN Ia is mag about 16.7. The CfA team spectrum (May 21.17) revealed that it is a reddened SN Ia near maximum. SN 2003ei: In [vsnet-campaign-sn 623] (May 21): >SN2003ei 20030331.5 <195:C KAI >SN2003ei 20030519.4 172:C KAI >SN2003ei 20030520.4 169:C KAI > ># SN 2003ei (16:28:40.30, +12:46:05.8 (J2000.0), offset = 4"W, 9"N) ># is hosted by UGC 10402, an interacting pair consists of two ># disturbed spiral galaxies. The given offset is measured from the ># nucleus of the northern component of the pair. The expected maximum ># of typical SN Ia is mag is consistent with the reported magnitudes. The CfA team also revealed that it is of type IIn (May 21.23 UT spectrum). It resembles to that of a lumunous SN IIn 1998S.
