Previous IAU Circulars
RA(J2000) = 03h 48m 43s Dec(J2000) = +45d 03' 31"with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). With the currently available data from ~T-50 s to ~T+30 s, the BAT light curve showed a single-peaked structure with a duration of about 10 sec. The peak count rate was ~500 counts/sec (15-350 keV), at ~2 sec after the trigger.
RA(J2000) = 03h 48m 44.3s Dec(J2000) = +45d 04' 46.9"with an uncertainty of 1.7 arcmin, (radius, sys+stat, 90% containment). The partial coding was 25%.
