    At 00:24:10 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 220620 ***A*** (trigger=1111002).  Swift slewed immediately to the burst.
The BAT on-board calculated location is 
RA, Dec 299.393, +35.002 which is 
   RA(J2000) = 19h 57m 34s
   Dec(J2000) = +35d 00' 06"
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 ~1007 counts/sec (15-350 keV), at ~6 sec after the trigger.
