RA(J2000) = 17h 47m 44s Dec(J2000) = -68d 15' 33"with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a single peak structure with a duration of about 40 sec. The peak count rate was ~5000 counts/sec (15-350 keV), at ~-13 sec after the trigger. (The peak occurred during a pre-planned slew and the nominal trigger time is the start of the first post-slew image.)
RA(J2000) = 17h 47m 41.47s Dec(J2000) = -68d 15' 03.6"with an uncertainty of 5.7 arcseconds (radius, 90% containment). This location is 35 arcseconds from the BAT onboard position, within the BAT error circle. No event data are yet available to determine the column density using X-ray spectroscopy.
