At 10:59:30 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 201229 ***A*** (trigger=1015088). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 210.708, +48.197 which is
RA(J2000) = 14h 02m 50s
Dec(J2000) = +48d 11' 50"
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 ~1327 counts/sec (15-350 keV), at ~2 sec after the trigger.
