TITLE: GCN GRB OBSERVATION REPORT NUMBER: 111 SUBJECT: SGR1627-41, BeppoSAX-GRBM detections DATE: 98/06/18 22:31:25 GMT FROM: Marco Feroci at IAS/CNR Frascati M. Feroci, E. Costa, L. Amati, L. Piro and B. Martino, Istituto di Astrofisica Spaziale (CNR, Rome), L. Di Ciolo and A. Coletta, BeppoSAX Science Operation Center (Rome), F. Frontera, Istituto Tecnologie e Studio Radiazioni Extraterrestri (CNR, Bologna), report: "The Gamma Ray Burst Monitor (GRBM) onboard BeppoSAX has detected bursts from a direction consistent with the new Soft Gamma-ray Repeater SGR1627-41 (Kouveliotou et al., GCN #107 and IAUC 6944). Two events were triggered on June 17.90091 (consistent with BATSE trigger n. 6834) and 18.15556. The duration of the events is about 90 and 40 milliseconds respectively. The spectral index, assuming a power law function, is (3.0+/-0.3) and (2.5+/-0.3) respectively in the 40-700 keV energy band. These detections are in agreement with those reported by BATSE and with the harder energy range of the GRBM. Data analysis is in progress to find out other bursts from the same source."
