A. Henden (USRA/USNO) and H. Harris (USNO),
on behalf of the USNO GRB team,
S. Klose, (Thueringer Landessternwarte Tautenburg),
on behalf of a much larger European team, report:
We have observed the error box of GRB 000418
with the NOFS 1.3-m automated telescope on
000426 UT with a total exposure time of 1800
seconds in Cousins R. At the position of the proposed
afterglow candidate (Klose et. al. GCN #645)
we find a faint source near our limiting
magnitude. With respect to the USNO-A2.0
star used by Mirabal et. al. (GCN #646, #650),
we obtain
RA 12:25:19.30 DEC +20:06:11.6 +/- 0.3 J2000
UT 000426.316 R=22.49 +/- 0.20
We will be calibrating this field in UBVRI
over the weekend.
