> SUPERNOVA 2001bt IN IC 4830
> R. Chassagne, Ste. Clotilde, Ile de Reunion, reports the discovery of an
> apparent supernova (mag about 15.0) on unfiltered CCD images taken with a
> 0.30-m f/2.7 telescope on May 24.0 and 24.9 UT. The object is located at
> R.A. = 19h13m46s.75, Decl. = -59o17'22".8 (equinox 2000.0), which is 27".7
> west and 17".1 north of the nucleus of IC 4830. An image of the same field
> taken on May 5.0 showed nothing at this position (limiting mag 19). The
> U.K. Schmidt image in the Digital Sky Survey (1975 May 10.7 UT) also showed
> nothing at this position (limiting mag 21).
