D.W. Fox and J.S. Bloom (Caltech) report on behalf of a larger
collaboration:
"We have observed the full error box of GRB020531 (Ricker et al., GCN
#1399) with the Palomar Oschin Telescope + NEAT with three 120s
exposures beginning on 04:50 UT 31 May 2002, less then 4.5 hours after
the burst. The summed exposure reaches to the POSS plate limit,
R~18. Visual comparison of the image against the Digitized Sky Survey
(DSS/SES) has not yet allowed us to identify any bright new stationary
objects. We identify two asteroids which are present at J2000
coordinates
Ast 1: 15:13:08.12 -19:22:13.1
Ast 2: 15:13:49.81 -19:29:13.1
at the epoch of our first image. Further analysis of these data are
in progress."
