At 06:12:38 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 160826 ***A*** (trigger=709907). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 183.074, -67.689 which is
RA(J2000) = 12h 12m 18s
Dec(J2000) = -67d 41' 19"
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 ~1335 counts/sec (15-350 keV), at ~1 sec after the trigger.
