TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1414 SUBJECT: GRB 020603: Optical Observations DATE: 02/06/06 19:42:19 GMT FROM: Melissa Nysewander at UNC,Chapel Hill M. Nysewander, L. Johnson, D. Moschler, J. Richuso (U. North Carolina), and D. Reichart (Caltech) report: We observed the entire ~19 square arcminute error box of the ~1.5 second duration GRB 020603 (GCN 1409, 1412) with the 0.6 meter Morehead Observatory telescope beginning 2.36 days after the burst. We integrated without filter for ~2800 seconds per pointing x 2 pointings through scattered cirrus and relatively high airmass. Visual comparison with the DSS reveals no transients down to our limiting magnitude, which we estimate to be V ~ 18.5 mag.
