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 15.5 +/- 0.2) on an unfiltered
image taken on Mar. 19.22 UT with the 0.41-m 'PROMPT
1' telescope located at Cerro Tololo. The new object,
which is also present in an image taken on Mar. 20.16
at mag approximately 15.2, is located at R.A. = 15h49m49s.23
+/- 0".1, Decl. = -29°23'09".7 +/- 0".1
(equinox 2000), which is about 3".1 west and 2".0
north of the center of the galaxy NGC 6000. Nothing
is visible at this position in archival images taken
on Feb. 22.25 and Mar. 12.33 (limiting mag 17.5). NGC
6000 was also the host galaxy of the type-II supernova
2007ch (cf. CBETs 961, 963).
