TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2561 SUBJECT: GRB 040403: Optical Observations DATE: 04/04/03 12:53:51 GMT FROM: Jane Moran at U.North Carolina J. Moran, M. Nysewander, and D. Reichart report on behalf of the FUN GRB Collaboration: We imaged the entire ~30 square arcminute error circle of the INTEGRAL GRB 040403 (Gotz et al., GCN 2560) with the 0.6-meter Morehead Observatory telescope beginning 70 minutes after the burst. We integrated in Rc for 4440 seconds under non-ideal conditions. Visual comparison to the DSS/POSS2-Red reveals no obvious new source to our limiting magnitude (Rc ~ 19 mag).
