At 05:44:52 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 201209 ***A*** (trigger=1011980). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 23.106, -1.763 which is
RA(J2000) = 01h 32m 25s
Dec(J2000) = -01d 45' 47"
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 ~8073 counts/sec (15-350 keV), at ~7 sec after the trigger.
