Reichart, 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 17.2 +/- 0.3)
on an R-band image taken on Apr. 28.33 UT with the 0.41-m 'PROMPT 4' telescope
located at Cerro Tololo.  The new object, which is also present in an image
taken on Apr. 29.32 at mag approximately 16.6 +/- 0.2, is located at R.A. =
22h10m09s.27 +/- 0".1, Decl. = -36o05'42".6 +/- 0".1 (equinox 2000), which is
about 9".2 west and 23".8 south of the center of the galaxy IC 5169.  Nothing
is visible at this position on archival images taken on Apr. 8.39 (limiting
mag 18.5) and 21.36 (limiting mag 19.0).
