TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1019 SUBJECT: GRB010324, optical observations DATE: 01/03/26 14:37:47 GMT FROM: Arne A. Henden at USNO/USRA A. Oksanen, H. Hyvonen (Nyrola Observatory); A. Price, D. West, G. Lubcke, D. Kaiser, D. Hurdis (AAVSO); M. O'Conner, D. Marcus, R. Pason, F. Chalupka, D. Hohman, W. Aquino (Buffalo Astronomical Association) report on behalf of the AAVSO International GRB network: We have observed the error box for the RXTE ASM GRB010324 (Hurley et al., GCN 1011) with a variety of telescopes and image scales. Based on comparison with the POSS-II red plate as digitized at USNO, we find no new object within the error box. A log of observations is given below. For the Filter field, C=unfiltered, R=Cousins R, I=Cousins I. The Delay field is the time since burst (010324.484 UTD).
