At 11:30:42 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 170126 ***A*** (trigger=735188). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 263.579, -64.757 which is
RA(J2000) = 17h 34m 19s
Dec(J2000) = -64d 45' 26"
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 ~3679 counts/sec (15-350 keV), at ~0 sec after the trigger.
