located at Cerro Tololo. The new object, which is also
present at mag approximately 16.8 in an image taken
on July 2.39, is located at R.A. = 3h41m31s.50 +/- 0".1,
Decl. = -19°54'00".4 +/- 0".1 (equinox 2000.0), which
is about 4".7 west and 17".9 north of the center of
the galaxy ESO 548-76. Nothing is visible at this position
on archival images taken on Jan. 9.12 and 12.10 (limiting
