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 possible supernova (mag approximately 17.2) on an
unfiltered image taken on Oct. 7.27 UT with the 0.41-m 'PROMPT 5' telescope
located at Cerro Tololo.  The new object, which is also present at mag
approximately 16.7 in an image taken on Oct. 15.3, is located at R.A. =
0h40m02s.48 +/- 0".2, Decl. = -56o09'29".9 +/- 0".2 (equinox 2000.0).
Nothing is visible at this position on archival images taken on Sept. 29.18
(limiting mag 18.5) and Sept. 16.22 (limiting mag 18.0).  Several galaxies
are present in the image, which make difficult any host identification.
