M. Nysewander, D. Reichart, J. Haislip report on behalf of the UNC GRB team
of the FUN GRB Collaboration:
Using a single 348 sec coadd from last night's SOAR data (Haislip et al.,
GCN 3919) and 7 USNO stars, we measure the coordinates of the afterglow to
be:
RA: 00:54:50.794
DEC: +14:05:09.42
with uncertainties of 1.6" in RA and 2.3" in DEC.
This is consistent with the astrometry of D'Avanzo et al. (GCN 3921) and
the refined coordinates of the X-ray afterglow (Mineo et al.; GCN 3920).
DR apologizes for the crudeness of our initial astrometry.
