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
16.3 +/- 0.3) on an unfiltered image taken on June 27.10 UT
with the 0.41-m 'PROMPT 3' telescope located at Cerro Tololo.
The new object, which is also present in an image taken on June
27.98 at mag approximately 15.5 +/- 0.2, is located at R.A.
= 15h54m50s.94 +/- 0".1, Decl. = -68°43'00".2 +/-
0".1 (equinox 2000.0), which is about 28".7 east and
0".8 north of the center of the galaxy ESO 68-12. Nothing
is visible at this position on archival images taken on June
1.19 and 11.08 (limiting mag 18.0).
