K. Ivarsen, A. Crain, D. 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 Apr. 3.36 UT with the 0.41-m 'PROMPT 3' telescope
located at Cerro Tololo.  The new object, which is also present at mag
approximately 17.5 +/- 0.4 in an image taken on Mar. 30.37, is located at
R.A. = 21h26m22s.20 +/- 0".1, Decl. = -40o51'48".6 +/- 0".1 (equinox 2000),
which is about 2".5 west and 4".7 south of the center of the apparent host
galaxy.  Nothing is visible at this position on archival images taken on
2008 Oct. 21.04 and 27.19 (limiting mag 18.5).
