RA(J2000) = 11h 06m 31s Dec(J2000) = -29d 06' 31"with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve shows an initial 1-2 sec spike at T0, and then smaller and longer peaks at ~T+20 sec and ~T+50 sec. structure with a duration of about 60 sec. The peak count rate was ~3000 counts/sec (15-350 keV), at ~0 sec after the trigger.
RA(J2000) = 11h 06m 34.7s Dec(J2000) = -29d 06' 18.3"with an uncertainty of 2.0 arcmin, (radius, sys+stat, 90% containment). The partial coding was 72%.
