[vsnet-alert 4817] SN 2000ce in UGC 4195

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

Dear SN watchers,

  Tim Puckett has discovered a bright SN (15 mag) in the northern
hemisphere.  It is his 8th discovery in this year (!, including ones
with his coleagues) and the other discovery (SN 2000cf) has already
reported.  Very admirable.

  IAUC 7417 tells that the discovery was made on May 8.13 UT at mag
15.0.  The location is R.A. = 8h05m09s.45, Decl. = +66o47'15".2
(2000.0), which is about 15" east and 17" north of the center of the
nearly face-on SBb galaxy UGC 4195.  The object is superimposed on the
north-eastern arm of the host galaxy, and no confusing foreground
stars are there.

  IAUC 7422 informs that the CfA group has performed spectroscopy of
this SN, which revealed that it is of type Ia just after the maximum.
Unfortunately, original IAUC 7417 mistaken in the name of the host
galaxy, and it leads the incorrect recession velocity in IAUC 7422 of
the current version (it will soon be corrected, I guess).  The
recession velocity of UGC 4195 is 4888 km/s (from NED/RC3), which
indicate that the reported magnitude is slightly brighter than the
typical SNe Ia at maximum.  It can be due to the proper motion of the
galaxy (receeding from us), or the intrinsically bright nature of this
SN.  Followup observation are surely encouraged. 

  The photometric sequence of the field of SN 2000ce has kindly been
provided by Prof. A. Henden at

, and the DSS reference image by O. Trondal at

Sincerely Yours,
