Supernova 1999da in Elliptical Galaxy NGC 6411

Supernova 1999da in NGC 6411 Date/Time: July 16th, 1999, 5:19 UT

The following is the data on Supernova 1999da:

Discovered: July 5th, 1999, by Lick Observatory Supernova Search team.

From IAU Bulletin 7219 (7/10/99):

A. V. Filippenko, U. of California at Berkeley, reports that a CCD spectrum obtained with the 3-m Shane reflector at Lick Observatory reveals SN 1999da to be of type Ia, but similar to the peculiar, subluminous type-Ia SNe 1986G or 1991bg. SN 1999da appears to be subluminous, and its host is an elliptical galaxy, consistent with previous indications that such type-Ia events tend to occur in elliptical galaxies.
