The observed light curve shows two separate\npeak structures with a duration (T90) of about 71 seconds. The fluence\nin 100-1000 keV was (1.1 +/-0.2) X 10^-5 erg/cm^2. The 1-s peak flux was\n0.9 +/-0.1 photons/cm^2/s in the same energy range.\n\nPreliminary result shows that time-averaged spectrum from T0-5 to\nT0+83 sec is well fitted by a single power law with a photon index\nof 1.7 +/-0.2.\n\nAll the quoted errors are at statistical 90% confidence level,\nin which the systematic uncertainties are not included.",
