TITLE: GCN GRB OBSERVATION REPORT NUMBER: 540 SUBJECT: GRB000210: BeppoSAX GRBM and WFC Detection DATE: 00/02/10 18:35:15 GMT FROM: Giangiacomo Gandolfi at IAS/CNR Frascati GRB000210: BeppoSAX GRBM and WFC Detection M. Stornelli, G. Celidonio, Scientific Operation Centre, Telespazio, Roma, J.M. Muller, J. In't Zand, Space Research Organization of the Netherlands (SRON), Utrecht, L. Amati, TESRE/CNR, Bologna, M. Feroci and G. Gandolfi, IAS/CNR, Roma, report: "The BeppoSAX Gamma Ray Burst Monitor (GRBM) and Wide Field Camera (WFC unit 1) observed a strong gamma-ray burst on February 10.36396 UT. A preliminary analysis reveals a duration of about 20 s in the GRBM, with a peak photon countrate of 22083 cts/s in the 40-700 keV energy band. In the WFC, the duration is the same and the peak flux is 7.4 Crab (2-26 keV). The position of the X-ray counterpart is R.A. = 01h59m14.9s Decl. = -40d40'.14 (equinox 2000.0) with a 99% error radius of 2'. An NFI follow-up is being carried on."
