    At 04:52:58 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 220701 ***A*** (trigger=1114034).  Swift slewed immediately to the burst.
The BAT on-board calculated location is 
RA, Dec 242.478, +55.420 which is 
   RA(J2000) = 16h 09m 55s
   Dec(J2000) = +55d 25' 14"
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 ~1167 counts/sec (15-350 keV), at ~0 sec after the trigger.
