Lopez, S. Silva, G. Folatelli, D. Iturra, R. Cartier, and F. Forster,
Universidad de Chile; and D. 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 17.4 +/- 0.2) on an unfiltered image taken on Oct. 3.16 UT
with the 0.41-m 'PROMPT 3' telescope located at Cerro Tololo.  The new object
is located at R.A. = 2h10m36s.63, +/- 0".1, Decl. = -53o45'59".5 +/- 0".1
(equinox 2000), which is about 0".6 west and 0".5 south of center of the
apparent host galaxy.  SN 2008gc is also present in images taken on Oct.
4.15 at mag approximately 17.3 +/- 0.2 and Oct. 6.04 at mag approximately
17.2.  Nothing is visible at this position on archival images taken on June
30.29 (limiting mag 17.5) and July 4.28 (limiting mag 18.0).
