    At 01:55:36 UT, the Swift Burst Alert Telescope (BAT) triggered and
    located GRB 190705 ***A*** (trigger=913042).  Swift slewed immediately to the burst.
    The BAT on-board calculated location is 
    RA, Dec 154.464, +41.481 which is 
       RA(J2000) = 10h 17m 51s
       Dec(J2000) = +41d 28' 53"
    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 ~898 counts/sec (15-350 keV), at ~0 sec after the trigger.
