    At 14:26:58 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 220629 ***A*** (trigger=1113743).  Swift slewed immediately to the burst.
The BAT on-board calculated location is 
RA, Dec 103.786, -1.493 which is 
   RA(J2000) = 06h 55m 09s
   Dec(J2000) = -01d 29' 33"
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 ~1431 counts/sec (15-350 keV), at ~6 sec after the trigger.
