[vsnet-campaign-sn 370] spectral types of recent SNe
Dear SN watchers,
IAUC 7846 informed the spectral types of recent SNe.
SN 2002bf:
In [vsnet-campaign-sn 357]:
># The host galaxy of SN 2002bf = CGCG 266-031 is a barred-spiral
># (SB(r)b:) galaxy. The expected maximum for typical SN Ia is mag
># about 16.6.
It is of type Ia at maximum on Mar 6-7 UT, with somewhat high
expansion velocity (CfA team and UCB-Keck team). Such high velocity
are observed among the luminous SNe Ia. The observation has not
reported other than the discovery (166:C on Feb. 24.3 UT).
SN 2002bi:
In [vsnet-campaign-sn 358]:
># The host of SN 2002bi is a spiral or irregular (Sdm:) galaxy UGC
># 8527. The expected maximum for typical SN Ia is mag about 16.6.
># SN locates quite near to the nucleus.
It is also of type Ia, but roughly 1 month past maximum on Mar. 7
(UCB - Keck team).
SN 2002bk:
In [vsnet-obs 38800]:
>SN2002bk 20020111.5 <195C PAL
>SN2002bk 20020209.28 185C PAL
>SN2002bk 20020303.3 191C PAL
It is again of type Ia, about 5 weeks past maximum on Mar. 7 (the
same observers). The recession velocity of the host galaxy was also
measured as 17000 km/s.
Sincerely Yours,
