    At 04:07:18 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 190613 ***A*** (trigger=908288).  Swift slewed immediately to the burst.
The BAT on-board calculated location is 
RA, Dec 182.559, +67.233 which is 
   RA(J2000) = 12h 10m 14s
   Dec(J2000) = +67d 13' 58"
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 ~1148 counts/sec (15-350 keV), at ~0 sec after the trigger.
