Foster, M. Nysewander, and A. LaCluyze, University of
North Carolina at Chapel Hill, on behalf of the CHASE
project, report the discovery of an apparent supernova
(mag approximately 17.1 +/- 0.3) on an unfiltered image
taken on June 5.40 UT with the 0.41-m 'PROMPT 3' telescope
located at Cerro Tololo. The new object, which is also
present at mag approximately 17.0 in an image taken
on June 8.44, is located at R.A. = 1h41m55s.93 +/- 0".1,
Decl. = -13°05'01".6 +/- 0".1 (equinox 2000.0), which
is about 11".8 east and 7".4 south of the center of
the galaxy NGC 655. Nothing is visible at this position
on archival images taken on 2009 Oct. 13.17 and Nov.
20.21 (limiting mag 18.5).
