Supernova 1997db in UGC 11861

Schwartz also reports his discovery of an apparent supernova on a CCD image taken on Aug. 2.30 UT. The following position and magnitude were measured by W. Offutt (Cloudcroft, NM) from an image supplied by Schwartz: R.A. = 21h56m20s.53, Decl. = +73o14'49".4 (equinox 2000.0), V = 16.9. Note that SN 1995ag was in the same galaxy (IAUC 6244). Filippenko et al. report that CCD spectra (range 330-1000 nm) obtained with the 3-m Shane reflector on Aug. 4 show that SN 1997db is a supernova of type II, many months past outburst and entering the nebular phase. There are prominent emission lines of [Ca II] 730-nm and the Ca II near-infrared triplet, as well as very strong H-alpha. SN 1997db is located about 14" west and 50" south from the ill-defined host-galaxy nucleus.
