RA(J2000) = 06h 14m 22s Dec(J2000) = +64d 05' 07"with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve shows a single peak with a duration of at least 10 sec. The peak count rate was ~1000 counts/sec (15-350 keV), at ~0 sec after the trigger.
RA(J2000) = 06h 14m 05.4s Dec(J2000) = +64d 04' 51.9"with an uncertainty of 1.8 arcmin, (radius, sys+stat, 90% containment). The partial coding was 15%.
