Ground analysis of the WXM data for the burst produced a location which was reported in a GCN Position Notice at 08:39 UT. Further ground analysis of the WXM data produced a refined location, which was reported in a second GCN Position Notice at 09:12 UT; an additional refinement was reported in a third Position Notice at 13:17 UT. The WXM localization SNR was 17. The refined WXM ground location can be expressed as an error box (90% confidence) of 230 sq-arcmin area centered at RA = 01h 33m 53s, Dec = +40d 27' 45" (J2000). The 4 corners of the WXM error box (90% confidence) are RA = 01h 32m 44s, Dec = +40d 23' 56" (J2000) RA = 01h 32m 47s, Dec = +40d 32' 48" (J2000) RA = 01h 35m 02s, Dec = +40d 31' 33" (J2000) RA = 01h 34m 58s, Dec = +40d 22' 40" (J2000) The burst duration in the 8-40 keV band was about 20 s. In the 8-40 keV band, the peak flux was >2 x 10-7 ergs cm-2 s-1 (ie > 5 x Crab flux; 1 s time scale) and the fluence was ~5 x 10-7 ergs cm-2 during the brightest 4 s of the burst .
