SUPERNOVA 2009mu IN ESO 374-3
     G. Pignata, Universidad Andres Bello; J. Maza, M. Hamuy, R. Antezana, L.
Gonzalez, P. Gonzalez, P. Lopez, S. Silva, G. Folatelli, R. Cartier, F.
Forster, S. Marchi, and A. Rojas, Universidad de Chile; B. Conuel, Wesleyan
University; and D. Reichart, K. Ivarsen, J. Haislip, 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 18.2 +/- 0.4) on an unfiltered image taken on Dec. 21.3 UT
with the 0.41-m 'PROMPT 5' telescope located at Cerro Tololo.  The new object,
which is also present in an image taken on Dec. 23.28 at mag approximately
18.3, is located at R.A. = 9h51m57s.75 +/- 0".1, Decl. = -33o04'42".4 +/-
0".1 (equinox 2000.0), which is about 4".0 east and 17".6 south of the center
of the galaxy ESO 374-3.  Nothing is visible at this position in a stack of
fifteen 40-s archival images taken with the same instrument between 2008 Oct.
13.35 and 2009 May 7.15 (limiting mag 20.0).
