At 16:07:43 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 160912 ***A*** (trigger=711914). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 301.518, +57.543 which is
RA(J2000) = 20h 06m 04s
Dec(J2000) = +57d 32' 36"
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 ~1545 counts/sec (15-350 keV), at ~151 sec after the trigger.
