[vsnet-alert 5588] SN 2000L in MCG -01-30-11

Dear SN watchers,

  IAUC 7566 informed that KAIT discovered an bright SN Ia.  It can
have a broad maximum, which indicate it would be an overluminous SN
Ia. 

  The discovery made by the image taken on Jan 18.4 UT when the new
object was mag about 15.4.  It was confirmed on an earlier image taken
on 2000 Dec. 31.4, when it was mag about 15.7.  The location is: R.A.
= 11h36m48s.83, Decl. = -8 35'07".0 (equinox 2000.0), which is about
4" north of the nucleus of nearly edge-on spiral (SAb: sp) galaxy MCG
-01-30-11.  It is almost overimposed on the bulge region.

  The spectrum has taken by CfA team on Jan 19.46 UT, which reveals
that SN 2000L is SN Ia about 1 week after maximum.  The recession
velocity of the host galaxy (4567 km/s) suggest that the typical SN Ia
would have the maximum brightness of mag 15.7.  Reported magnitude is
somewhat brighter, and the peak of the light curve seems to be broader
than the typical one.  So, it can be an overluminous SN Ia like SN
1991T.  The follow-up photometry of this bright example is very
important for the confirmation of "bright SN Ia will decline slowly"
relation. 

Sincerely Yours,
Hitoshi Yamaoka, Kyushu Univ., Japan
