[vsnet-alert 2936] SN 1999bz in UGC 8959

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

Dear SN watchers,

  IAUC 7157 informed that LOSS KAIT team reported a new object in the
dim face-on spiral galaxy (RC3 classified it as Sm) UGC 8959.  The
location of this object is: R.A. = 14h01m46s.75, Decl. = +68o52'46".5
(2000.0), which is about 12" west and 8" north from the core of UGC
8959.  In the RC3, the coordinate of UGC 8959 is poor; the center of
UGC 8959 is about R.A. = 14h01m49s.26, Decl. = +68o52'36".9 (2000.0). 

  The position of SN 1999bz is coincident with the spiral arm of the
host.  Along the arms, the bright HII regions (probably) exist; whose
offsets from nucleus are 16"E4"N, 4"E17"N.  There is a small
(accompanied?) elliptical galaxy at about 3"W45"N from the nucleus of
UGC 8959, and a foreground star at 7"W52"N from the core of UGC 8959.

  The recession velocity of this galaxy is very ambiguous:  RC3 gives
511 km/s from the radio (H 21cm) observation, besides the optical
observation obtained the value 25731 km/s.  If the former is true, UGC
8959 is very nearby one.  However, the brightness of this galaxy
supports the latter value.  

  Now SN 1999bz is about 17.6 mag, which is rather bright as cz =
25000 km/s even if it is of type Ia.  Followup observations are
needed.  

Sincerely Yours,
