TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2032 SUBJECT: GRB 030324, optical search DATE: 03/03/30 22:30:48 GMT FROM: Peter Garnavich at U of Notre Dame K. Luhman, T. Megeath, T. Spahr, K.Z. Stanek (CfA), S. Holland P. Garnavich (Notre Dame) We observed the error circle of GRB 030324 (GCN 1954) with the Fred L. Whipple 1.2-m telescope and R filter on three epochs: Date Time t (days) R_lim Mar. 24 06:25 0.134 22.4 Mar. 24 10:37 0.309 22.5 Mar. 26 07:52 2.194 22.7 where R_lim is the 3-sigma limiting magnitude. Visual comparison and subtraction of the the epochs reveals no new, strongly variable sources down to the corresponding limits. A star present on the digitized sky survey at 13:37:19.23 -00:16:21 (2000) is seen to vary between 19.2 and 18.8 in the R-band. Deep R-band images centered on the error circle, but covering only the inner 7.4' diameter field were obtained with the Magellan 6.5-m Clay telescope and LDSS2 imaging/spectrograph: Date Time t (days) R_lim Mar. 24 08:14 0.210 23.1 Mar. 25 05:35 1.100 23.3 and subtraction of these images does not reveal any new, variable sources.
