    At 12:25:32 UT, the Swift Burst Alert Telescope (BAT) triggered and
    located GRB 170714 ***A*** (trigger=762535).  Swift slewed immediately to the burst.
    The BAT on-board calculated location is 
    RA, Dec 34.321, +1.987 which is 
       RA(J2000) = 02h 17m 17s
       Dec(J2000) = +01d 59' 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 ~1195 counts/sec (15-350 keV), at ~7 sec after the trigger.
