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 16.0 +/- 0.2) on
unfiltered images taken on Jan. 2.11 and 3.21 UT with the 0.41-m 'PROMPT 3'
telescope located at Cerro Tololo.  The new object is located at R.A. =
1h52m44s.34 +/- 0".1, Decl. = -3o23'48".2 +/- 0".1 (equinox 2000), which is
about 6".4 west and 7".3 north of the center of the apparent host galaxy.
Nothing is visible at this position on archival images taken on 2007 Dec.
9.16 and 13.10 (limiting mag 18.0).
