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 16.4 +/- 0.3) on an
unfiltered image taken on Jan. 4.11 UT with the 0.41-m 'PROMPT 3' telescope
located at Cerro Tololo.  The new object, which was confirmed at mag
approximately 15.5 +/- 0.3 in an image taken on Jan. 5.06, is located at R.A.
= 4h59m23s.56 +/- 0".1, Decl. = -11o07'50".1 +/- 0".1 (equinox 2000), which
is about 9".8 east and 6".1 north of center of the galaxy NGC 1725.  Nothing
is visible at this position on archival images taken on 2008 Dec. 23.17 and
29.12 (limiting mag 18.0).
