The on-ground calculated location, using\nthe Fermi GBM trigger data, is RA = 281.22, Dec = -2.12 (J2000 \ndegrees, equivalent to J2000 18h 45m, -2d 7'), with a statistical\nuncertainty of 8.9 degrees (radius, 1-sigma containment, statistical\nonly; there is additionally a systematic error which is currently\nestimated to be 2 to 3 degrees).\n\nThe 3-sigma error region for the burst contains several known\nmagnetars, but does not include the recently discovered magnetar\nat the galactic center, SGR J1745-29 (Atel #5020).\n\nThe burst consists of a single pulse with a duration of\nT90 = 20 +/- 9 ms.\n\nThe burst spectrum is adequately fit by a single blackbody with a\nkT = 9.8 +/- 0.7 keV.  The corresponding peak flux integrated over \n4ms (8-200 keV) is (2.2 +/- 0.4)E-06 erg/s/cm^2. The fluence during \nT0-0.020s to T0+0.016s is (3.8 +/- 0.4)E-8 erg/cm^2.\n\nThe analysis results presented above are preliminary.\"",
