TITLE: GCN CIRCULAR NUMBER: 772 SUBJECT: GRB000730, Gamma Ray Observations DATE: 00/08/16 15:12:44 GMT FROM: Srikanta Sinha at ISRO/ISAC S. Sinha, P. sreekumar, K. kasturirangan, on behalf of SROSS C-2 (INDIAN GRB EXPERIMENT) team report: SROSS C-2 observed this burst at 1800.966 s UT (this time may be off by a few hundred ms). as observed by SROSS C-2, it had a duration (T90) of 0.352 secs (352 ms), a 20-1024 keV fluence (not corrected for the sec (theta) factor since we donot know its location) equal to 6.56.10-5 +- 2.18.10-6 ergs cm-2. The peak flux (256 ms) in 20-100 keV band is 8.81 photons cm-2 sec-1 and the peak flux (256 ms) in 100-1024 keV band is 9.85 photons cm-2 sec-1. The hardness ratio ((100-1024 keV)/(20-100 keV)) for this burst is equal to 0.47 +- 0.082. This message is quotable in publications. -Srikanta Sinha, on behalf of the SROSS C-2 (INDIAN GRB EXPT. TEAM) at the Technical Physics Division, ISRO Satellite Center, Bangalore-560 017, INDIA.
