The spectrum over the interval from\nT-11 to T+44 seconds can be fit with a power law with photon index\n1.56 +/- 0.18 and yields a fluence of 1.8 X10^-6 erg/cm^2 in the\n15-350 keV band.  The peak flux in a 1-sec wide window starting at\nT+17.4 seconds is 0.6 +/- 0.2 ph/cm^2/sec.  The light curve is a long\nsmooth \"bump\" with weak, if any, structure.",
