On behalf of the USNO GRB team, F. Vrba and B. Canzian, report
two additional R-band photometric measurements of the GRB 000926
optical counterpart, discovered by Gorosabel et al. (GCN 803)
and Dall et al. (GCN 804). Our observations were obtained with
the USNO, Flagstaff Station, 1.0-m telescope. These measurements
are based on a preliminary photometric calibration from a limited
number of standard stars.
UT Date Magnitude
Sep 28.097 R = 19.70 +/- .03
Sep 29.146 R = 21.05 +/- .04
If weather permits at a later date, we will produce a fully-calibrated
UBVRI standard sequence, as we have for several earlier GRB fields.
