Dear SN watchers,

  IAUC 8023 informed the types of recent two SNe determined by the CfA
team.

SN 2002je:
In [vsnet-obs 42363] (Nov. 22):
>SN2002je  20021031.2  <190:C  KAI
>SN2002je  20021120.2   177:C  KAI
>SN2002je  20021121.1   175:C  KAI
>
># LEDA 212525 = 2MASXi J0027225+241055, a host galaxy of SN 2002je
># (0:27:22.42, +24:10:59.1 (J2000.0), offset = 2"W, 3"N), is a dim
># galaxy probably a companion of UGC 261.  If it is the case, the
># expected maximum for typical SN Ia is mag about 16.7.

It is type II SN near the maximum on Nov. 28.

SN 2002jg:
In [vsnet-obs 42396] (Nov. 25)
>SN2002jg  20021118.2  <195:C  KAI
>SN2002jg  20021123.2   170:C  KAI
>SN2002jg  20021124.1   168:C  SCH
>SN2002jg  20021124.2   168:C  KAI
>SN2002jg  20021125.2   166:C  KAI
>
># NGC 7253 = Arp 278, a host galaxy of SN 2002jg (22:19:28.80,
># +29:23:04.5 (J2000.0)), is an interacting triple galaxies.  A offset
># of SN 2002jg from the brightest nucleus of the southeastern galaxy
># (NGC 7253B = UGC 11985 = MCG +05-52-011) is 20"W and 13"S.  There
># are several foreground stars and H II regions within the host, so be
># careful in the identification.  The expected maximum for typical SN
># Ia is mag about 15.8, unless it would be reddened by the
># interstellar matter in the host galaxy. 

It is type Ia SN at the maximum light on Nov. 28, with a notable
reddening.
