At 21:41:03 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 131004 ***A*** (trigger=573190). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 296.151, -2.960 which is
RA(J2000) = 19h 44m 36s
Dec(J2000) = -02d 57' 35"
with an uncertainty of 3 arcmin (radius, 90% containment, including
systematic uncertainty). The BAT light curve showed a [**double-peaked**]
structure with a duration of about TTT sec. The peak count rate
was ~8757 counts/sec (15-350 keV), at ~0 sec after the trigger.
