[vsnet-alert 1656] SN 1998an

[Yamaoka Hitoshi <yamaoka@rc.kyushu-u.ac.jp>]

Dear all,

  SN 1998an has discovered in UGC 3683 by R. Arbour, UK (maybe an
amateur astronomer). Congratulations, Ron!

  According to IAUC 6871 (also reported by Dr. Sala in ISN_chat), SN
1998an locates R.A. = 7h08m17s.04, Decl. = +46o06'55".3 (2000.0),
which is 32" east and 3" south of the host galaxy. 

  The host galaxy is of type S0. Spectroscpoic observation has not
reported, but it is suspected that SN 1998an is of type Ia according
its host galaxy. The recession velocity of the host is 5623 +- 155
km/s (rc3 value), which indicates that the host galaxy is about 5-6
times beyond as Virgo cluster. The peak magnitude of typical SN Ia for
this distance would be 15.5-16 (V or B). 

  IAUC 6871 tells that the magnitude of this SN at discovery is about
15.3. It could be near the maximum. Following photometries (and
spectroscpoic confirmations) are encouraged.

Sincerely Yours,
Hitoshi Yamaoka, Kyushu Univ., Japan
