SUPERNOVA IN ANONYMOUS GALAXY
T. Puckett, Mountain Town, GA, A. Sehgal, Woodinville, WA, Jack Newton, Osoyoos BC report their discovery of an apparent supernova (mag 17.5) on an unfiltered CCD frame (limiting mag 20.5) taken with the Puckett Observatory 0.60-m automated supernova patrol telescope on Jul. 4.13 UT. The candidate is located at R.A. = 17h01m03s.64, Decl. = +33o28'45".0 (equinox 2000.0), which is 7".01 west and 13".4 north of the center of the host galaxy.
The new object was also present on an unfiltered CCD frame taken by J. Newton, Newton Observatory B & B, Osoyoos, BC, taken with a 0.40-m reflector on July 6.55 UT, but does not appear on Palomar Sky Survey images taken on 1993 Apr. 04 (limiting mag about 21.0) ,1989 Jun. 29 (limiting mag about 21.0) or 1954 May 27 (limiting mag about 20.0).

SUPERNOVA IN GALAXY OFFSET FROM GSC 2594:1086
The candidate is located at R.A. = 17h01m03s.64, Decl. = +33o28'45".0

SUPERNOVA 2000ct IN ANONYMOUS GALAXY
S. Jha, P. Challis and R. Kirshner, Harvard-Smithsonian Center for
Astrophysics, report that a spectrum of SN 2000ct, obtained by
A. Mahdavi on July 7.24 UT with the F. L. Whipple Observatory 1.5-m telescope
(+ FAST spectrograph), shows it to be a type IIn supernova at an early
epoch. The spectrum exhibits a very blue continuum, with strong Balmer
emission lines as well as weak He I (rest 587.6 nm) emission. The
Balmer lines consist of a narrow component (FWHM = 1000 km/s) on top
of a broader base (FWHM = 3000 km/s). Cross-correlation of the host
galaxy spectrum with an emission-line template yields a recession
velocity of 8950 +/- 30 km/s.
