At 16:16:54 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 201024 ***A*** (trigger=1001628). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 244.864, -15.822 which is
RA(J2000) = 16h 19m 27s
Dec(J2000) = -15d 49' 18"
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 ~960 counts/sec (15-350 keV), at ~0 sec after the trigger.
