LaCluyze, University of North Carolina at Chapel Hill,
on behalf of the CHASE project, report the discovery
of an apparent supernova (mag approximately 18.2 +/-
0.4) on an unfiltered image taken on Jan. 25.30 UT with
the 0.41-m 'PROMPT 4' telescope located at Cerro Tololo.
The new object, which is also present at mag approximately
18.4 in an image taken on Jan. 29.26, is located at
R.A. = 13h14m47s.88 +/- 0".1, Decl. = -15°58'24".8
+/- 0".1 (equinox 2000.0), which is about 1".9
east and 2".3 south of center of the apparent host
galaxy. Nothing is visible at this position on archival
images taken on 2010 Jan. 2.31 (limiting mag 18.5) or
in a stack of twenty 40-s images taken between 2008
Dec. 26.33 and 2009 Jun. 25.05 (limiting mag 20.5).
