At 06:27:58 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 201128 ***A*** (trigger=1009679). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 223.136, +26.678 which is
RA(J2000) = 14h 52m 33s
Dec(J2000) = +26d 40' 41"
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 ~1679 counts/sec (15-350 keV), at ~2 sec after the trigger.
