RA(J2000) = 12h 31m 53s Dec(J2000) = 09d 06' 11”with an uncertainty of 2 arcminutes (radius, 90% containment, including systematic uncertainty). The currently-available BAT light curve shows a ~0.1 second long peak, with a possible smaller peak 0.3 seconds earlier. The peak value on a 64 ms timescale is ~3000 counts/s (15-350 keV) at the trigger time.
