    At 11:14:00 UT, the Swift Burst Alert Telescope (BAT) triggered and
    located GRB 160607 ***A*** (trigger=689597).  Swift slewed immediately to the burst.
    The BAT on-board calculated location is 
    RA, Dec 13.663, -4.948 which is 
       RA(J2000) = 00h 54m 39s
       Dec(J2000) = -04d 56' 52"
    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 ~33307 counts/sec (15-350 keV), at ~12 sec after the trigger.
