As observed by SROSS C-2, it \nhad a duration (T90) of 1.20 +- 0.05 secs. Its fluence in the 20-100 keV \nband is equal to 1.41.10-7 +- 2.0.10-8 ergs cm-2 and in the 100-1024 keV \nband is equal to 5.59.10-5 +- 2.35. 10-6 ergs cm-2 respectively. These \nfluences are not corrected for the cos(theta) factor since the direction \nto this burst is not known to us yet. The peak flux (256 ms) in the \n20-100 keV band is 4.73 photons cm-2 sec-1 and the peak flux (256 ms) in \nthe 100-1024 keV band is 6.29 photons cm-2 sec-1. The hardness ratio for \nthis burst (when the signal peaks in the 100-1024 keV channel) is equal \nto 0.56 +- 0.15. Our hardness ratio is defined as [counts(100-1024 \nkeV)/counts (20-100 keV)]. For 21 SROSS C-2 GRBs that have common BATSE \ntriggers, we find the mean hardness ratio is 0.97 +- 0.08 and the std. \ndeviation of the hardness distribution is equal to 0.37.\n        This message is citable.\n\n-Srikanta Sinha, on behalf of the SROSS C-2 (INDIAN GRB EXPT. TEAM) at \nthe Technical Physics Division, ISRO Satellite Center, Bangalore-560 017, \nINDIA.\n\n-------------------------------------------------",
