    At 22:59:18 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 201116 ***A*** (trigger=1006906).  Swift slewed immediately to the burst.
The BAT on-board calculated location is 
RA, Dec 85.776, +25.233 which is 
   RA(J2000) = 05h 43m 06s
   Dec(J2000) = +25d 13' 57"
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 ~4433 counts/sec (15-350 keV), at ~179 sec after the trigger.
