R. J. Cool, J. J. Schaefer (University of Wyoming) reporting on behalf of
the University of Wyoming GRB Response Team under the direction of R.
Canterna:
We observed the optical afterglow of GRB 021004 (GCN #1564) with the
Red Buttes Observatory 0.6 meter telescope, operated through the
University of Wyoming, between 4:37 UT and 6:25 UT on October 5 2002.
All observations were completed in the R-band under unfavorable
conditions.
We find R-band magnitudes for two epochs:
UT R_mag
======================
04:52:36 19.14
06:20:25 19.23
Typical errors on these values are +/- 0.1 mag. Calibration was completed
assuming the USNO star from Weidinger (GCN #1573) has an R magnitude of
15.64. Further analysis and observations are scheduled in the coming
days.
