Newman, on behalf of the SDSS GRB team, report:\n\n\"We have observed the field of GRB020531 (=H2042) (GCN 1399) using the\nSDSS 0.5-m \"Photometric Telescope\" (PT) at APO under clear skies, a\nbright moon, and poor seeing on UTC 2002 May 31 from 04:54 to 09:32\nUTC, beginning less than 4.5 hours after the burst.  We took a series\nof ten 600 second r'-band exposures and fifteen 600 second i'-band\nexposures (41.5' x 41.5' field of view) that cover the entire improved\nHETE error rectangle for GRB020531 (GCN 1399).  The summed images in r'\nreach deeper than the POSS plate limit, R~18.  Visual comparison of the\nimages and the DSS has not yet allowed us to identify any bright new\nobject.\"\n\nThis message is citable.",
