The onboard\nprocessing found a source that was not significant enough to initiate a\nburst response. Routine processing on the ground of failed triggers found\na significant source (9.7 sigma) at RA, Dec 268.449, +80.143 which is:\n\nRA 17h 53m 47.7s (J2000)\nDec 80d 8m 35s (J2000)\n\nwith an uncertainty radius of 2.5 arcmin (90% containment). The source\nwas 58% coded.\n\nT90 was 9 +- 2 sec. The peak count rate was 600 counts/sec (15-350 keV).\nUsing the data set from T-2 to T+8 sec, the mask-weighted light curve\nshows a single roughly symmetrical peak.\n\nThe power-law index of the time averages spectrum is 1.1 +- 0.2. The\nfluence in the 15-150 keV range from T-2 to T+8 sec was\n(2.9 +- 0.5) x 10-07 ergs/cm2. The 1-sec peak flux was 0.4 +- 0.2\ncounts/cm2/sec. All uncertainties are 90% confidence.\n\nSwift is executing a TOO to the position of this burst, and preliminary\nXRT and UVOT results should be available in a few hours.",
