unfiltered image taken on Mar. 11.17 UT with the 0.41-m 'PROMPT 4' telescope
located at Cerro Tololo.  The new object, which is also present in an image
taken on Mar. 12.15 at mag approximately 16.2 +/- 0.2, is located at R.A. =
12h59m46s.00 +/- 0".1, Decl. = -29o36'07".5 +/- 0".1 (equinox 2000), which is
about 1".4 east and 7".0 south of the center of the galaxy ESO 443-21.
Nothing is visible at this position on archival images taken on Feb. 24.18
(limiting mag 18.5) and Mar. 3.15 (limiting mag 17.5).
