TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1083 SUBJECT: BeppoSAX/GRBM detection of GRB010728 DATE: 01/07/30 16:56:05 GMT FROM: Marco Feroci at IAS/CNR Frascati M. Feroci (IAS/CNR, Rome), C. Guidorzi (Univ. of Ferrara) and F. Frontera (Univ. of Ferrara and ITESRE/CNR, Bologna), report on behalf of the BeppoSAX GRBM Team: "The BeppoSAX Gamma Ray Burst Monitor (GRBM) was triggered by a gamma ray burst on July 28, 2001, 19:24:45.028 UT (GRBM automatic alert n.265). The event observed by the RXTE/ASM on the same day at 19:24:47.23 UT (BACODINE notice on 30 July 2001, 16:06:22 UT) is therefore most likely the same event. As seen by the GRBM in the 40-700 keV energy range, the event was rather weak, showing a peak flux of about 240 counts/s, and approximately 8 s long." This message may be cited.
