SUPERNOVA 2010F IN NGC 3120

Silva, G. Folatelli, R. Cartier, F. Forster, S. Marchi, and A. Rojas,

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 14.8 +/- 0.1) on an unfiltered image
taken on Jan. 13.26 UT with the 0.41-m 'PROMPT 3' telescope located at Cerro
Tololo.  The new object, which was confirmed at mag approximately 14.7 on
Jan. 14.10, is located at R.A. = 10h05m21s.05 +/- 0".1, Decl. = -34o13'21".0
+/- 0".1 (equinox 2000.0), which is about 24".8 west and 9".1 south of the
center of the galaxy NGC 3120.  Nothing is visible at this position on
archival images taken on Dec. 24.22 (limiting mag 18.0) and Nov. 14.31
(limiting mag 18.5).  The type-II supernova 1999ca also appeared in this
galaxy (cf. IAUCs 7158, 7160, 7161).
