[vsnet-alert 1809] SN 1998cf in NGC 3504

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

Dear SN fans,

  IAUC 6914 has noticed that a new SN was discovered near the center
of NGC 3504.  This new star locates at R.A. = 11h03m11s.21, Decl. =
+27o58'21".0 (2000.0), which is about 5" south of the center of the
host.  It should be noted that this galaxy has apparent double
nucleus. 

  Spectroscopy of this object in near-IR region shows the Ca II P-Cyg
profile, which indicate that this is really a supernova.  However, the
type of it has not determined by that. 

  NGC 3504 is rather nearby object, which m-M is about 1 mag larger
than that of M87.  It implies that the expected magnitude at maximum
would be about 13.5 mag if it is of type Ia, and 2 mag dimmer if not. 
It is not certain whether it is effected by absorption, because new
star has been observed (even discovery) in IR.  Optical followup is
strongly encouraged.

Sincerely Yours,
Hitoshi Yamaoka, Kyushu Univ., Japan
