Hill, on behalf of the CHASE project, report the discovery of an apparent
supernova (mag approximately 17.8) on unfiltered images taken on Nov. 17.13
and 18.04 UT with the 0.41-m 'PROMPT 3' telescope located at Cerro Tololo.
The new object is located at R.A. = 1h57m08s.66 +/- 0".1, Decl. = +4o05'07".3
+/- 0".1 (equinox 2000.0), which is about 2".6 west and 8".6 north of the
center of the apparent host galaxy.  Nothing is visible at this position in
a stack of thirty-one 40-s images taken between June 17.42 and Oct. 12.22
(limiting mag 20.0).
