report:
We have an independent detection of a new source in the revised SAX
error box (GCN 960). Its position, based on the GSC, agrees with that
of Henden (GCN 962): 14:52:12.55 43:01:06.26 (J2000).
Comparing to star "A" (R=17.0) from the USNO catalog (located at
14:52:07.55 42:58:48.66), we estimate the R-band magnitude of the
possible GRB010221 afterglow to be R=18.4\pm 0.1.
