Dear SN watchers, The UCB team report the spectral classifications of five recent SNe in IAUC 8083. All spectra were taken with Keck I on Feb. 27 UT. SN 2003V: In [vsnet-campaign-sn 547] (Jan. 29): >SN2003V 20021213.0 <222C PAL >SN2003V 20030116.16 182C PAL >SN2003V 20030116.18 182C PAL >SN2003V 20030116.20 182C PAL >SN2003V 20030125.0 184C PAL > ># A host galaxy of SN 2003V (3:05:43.05, -1:24:12.8 (J2000.0), offset ># = 3"W, 2"N) is a small and dim (mag about 18.5) galaxy APMUKS(BJ) ># B030310.79-013550.9. It was revealed to be type Ia SN, about 2 months after maximum on Feb. 27 UT. SN 2003ah: In [vsnet-campaign-sn 556] (Feb. 10): >SN2003ah 20030129.2 <185:C KAI >SN2003ah 20030208.2 173:C KAI >SN2003ah 20030209.2 170:C KAI > ># A host galaxy of SN 2003ah (4:43:08.54, +0:46:00.4 (J2000.0), offset ># = 7"W, 7"N) is an anonymous edge-on spiral galaxy, which is located ># about 1' north of a pair of galaxies UGC 3141. The SN is ># superimposed on the outermost disk region. If the host galaxy is ># the same distance as UGC 3141, the expected maximum for typical SN ># Ia is mag about 16.0. It is also type Ia SN, about 12 days after maximum on Feb. 27. The recession velocity of the host galaxy was not reported. SN 2003av: In [vsnet-campaign-sn 565] (Feb. 22): >SN2003av 20030116.0 <210C PAL >SN2003av 20030204.28 196C PAL >SN2003av 20030210.0 195C PAL >SN2003av 20030218.0 197C PAL >SN2003av 20030219.0 200C PAL > ># SN 2003av (8:01:32.57, +02:48:27.9 (J2000.0), offset 3"E, 1"N) is ># hosted by a dim anonymous galaxy, which is a probable member of ># distant cluster. It is yet another SN Ia, about 2 weeks after maximum on Feb. 27. SN 2003ax: In [vsnet-campaign-sn 567] (Feb. 25): >SN2003ax 20030126.0 <195C PAL >SN2003ax 20030209.3 187C PAL >SN2003ax 20030218.0 184C PAL >SN2003ax 20030219.0 186C PAL >SN2003ax 20030222.0 188C PAL >SN2003ax 20030223.0 190C PAL > ># SN 2003ax (8:08:35.53, +7:46:42.2 (J2000.0), offset = 4"W, 1"N) is ># hosted by an anonymous spiral galaxy making a distant cluster. It is also a SN Ia, about 2 weeks after maximum on Feb. 27. SN 2003bf: In [vsnet-campaign-sn 568] (Feb. 28) >SN2003bf 20030203.24 <208C NEM >SN2003bf 20030218.45 176C NEM >SN2003bf 20030221.35 172C NEM > ># SN 2003bf (8:08:26.35, +12:19:56.2 (J2000.0), offset = 4"W, 1"S) is ># hosted by LEDA 100775 = 2MASXi J0808266+121957, a dim ># apparently disk galaxy. The expected maximum for typical SN Ia is ># coincident to the reported magnitudes. It is of type Ia around maximum on Feb. 27.
