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 at mag
approximately 13.3 on an unfiltered CCD image taken on Sept. 29.31 UT with the
0.41-m 'PROMPT 5' telescope located at Cerro Tololo. The new object, which is
also present in images taken on Sept. 16.38 (at mag approximately 12.8) and
Sept. 30.27 (mag approximately 13.5), is located at R.A. = 7h02m43s.63 +/-
0".1, Decl. = -28o37'25".2 +/- 0".1 (equinox 2000.0), which is about 42".5
east 265" north of center of the galaxy NGC 2325 (given the large distance
from the host, the membership is not completely secure). Nothing is visible
at this position on archival images taken on Feb. 23.07 (limiting mag 17.5)
and Jan. 14.18 (limiting mag 18.0).
NOTE: These 'Central Bureau Electronic Telegrams' are sometimes
superseded by text appearing later in the printed IAU Circulars.
