    At 16:09:14 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 220706 ***A*** (trigger=1114937).  Swift slewed immediately to the burst.
The BAT on-board calculated location is 
RA, Dec 0.587, -16.391 which is 
   RA(J2000) = 00h 02m 21s
   Dec(J2000) = -16d 23' 28"
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 ~1504 counts/sec (15-350 keV), at ~1 sec after the trigger.
