    At 13:58:04 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 220714 ***A*** (trigger=1116221).  Swift slewed immediately to the burst.
The BAT on-board calculated location is 
RA, Dec 47.072, -19.334 which is 
   RA(J2000) = 03h 08m 17s
   Dec(J2000) = -19d 20' 02"
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 ~5499 counts/sec (15-350 keV), at ~13 sec after the trigger.
