[vsnet-alert 1991] SN 1998dh (revised)

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

Dear SN watchers,

  According to IAUC 6978, the Lick group has discovered an apparent
supernova in NGC 7541, which is SBbc galaxy and makes a group with NGC
7537.  The location of this new object is: R.A. = 23h14m40s.31, Decl.
= +04d32'14".1 (2000.0).  The offset from the nucleus of the host is
about 54" west and 10" north.  Note that there is a condensation in
the host galaxy on the eastern arm.  The image taken by S. Massaro on
20.98 UT and other informations are available at 
http://vsnet.kusastro.kyoto-u.ac.jp/vsnet/SNe/sn1998dh.html .

  SN 1998dh was 16.8 mag at July 20.5 UT and rised to 15.3 mag at 24.5
UT (unfiltered CCD mag).  Surely it is in the rapid-rising phase!  The
spectroscopy shows that it is of type Ia before maximum (IAUC 6980). 
Another report told that it was 14.4 mag at July 28.25 UT (B. King,
[vsnet-obs 13461].)

  Typical SNeIa on this distance will shine at 14.4 mag or so around
its maximum.  Followup photometries are highly recommended. 

Sincerely Yours,
Hitoshi Yamaoka, Kyushu Univ., Japan
