Harvanek, A. N. Kleinman, S. Kleinman, J. Krzesinski, D. Long, and P.
R. Newman, on behalf of the SDSS GRB team, report:
"We have observed the field of GRB020531 (=H2042) (GCN 1399) using the
SDSS 0.5-m "Photometric Telescope" (PT) at APO under clear skies, a
bright moon, and poor seeing on UTC 2002 May 31 from 04:54 to 09:32
UTC, beginning less than 4.5 hours after the burst. We took a series
of ten 600 second r'-band exposures and fifteen 600 second i'-band
exposures (41.5' x 41.5' field of view) that cover the entire improved
HETE error rectangle for GRB020531 (GCN 1399). The summed images in r'
reach deeper than the POSS plate limit, R~18. Visual comparison of the
images and the DSS has not yet allowed us to identify any bright new
object."
