The BAT ground-calculated\nposition is (RA,Dec) = 18.130, 55.796 deg {1h 12m 31.3s, 55d 47' 44.7\"} (J2000)\n+- 0.7 arcmin, (radius, sys+stat, 90% containment).  The partial \ncoding was 90%.\n\nThe mask-weighted light curve shows a single broad peak from T-4 sec to T+7 sec\nT90 (15-350 keV) is 8.1 +- 1 sec (estimated error including systematics).\n\nThe time-averaged spectrum from T-4.2 to T+7.0 is best fit by\na power law with an exponential cutoff.  This fit gives a photon index\n1.11 +- 0.32, and Epeak of 73 +- 18 keV (chi squared 54.91 for 56 d.o.f.).\nFor this model the total fluence in the 15-150 keV band is\n9.8 +- 0.5 x 10^-7 erg/cm2 and the 1-sec peak flux measured from\nT+0.07 sec in the 15-150 keV band is 2.7 +- 0.2 ph/cm2/sec.\nA fit to a simple power law gives a photon index of 1.71 +- 0.07\n(chi squared 67.23 for 57 d.o.f.).  All the quoted errors are at the 90%\nconfidence level.",
