The BAT light curve shows a small peak at T_zero and then two large peaks at T+130 and T+175 sec with a duration of at least 200 sec. The peak count rate was ~2500 counts/sec (15-350 keV), at ~T+130 sec after the trigger.
RA(J2000) = 06h 43m 31.58s Dec(J2000) = +50d 12' 14.4"with an uncertainty of 5.2 arcseconds (radius, 90% containment). This location is 7.3 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.
