At :: UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB ***A*** (trigger=1440319). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec , which is
RA(J2000) = h m s
Dec(J2000) = d ' "
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 ~16539 counts/sec (15-350 keV), at ~0 sec after the trigger.
