    At 09:43:58 UT, the Swift Burst Alert Telescope (BAT) triggered and
    located GRB 161030 ***A*** (trigger=719854).  Swift slewed immediately to the burst.
    The BAT on-board calculated location is 
    RA, Dec 288.803, +10.941 which is 
       RA(J2000) = 19h 15m 13s
       Dec(J2000) = +10d 56' 29"
    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 ~1382 counts/sec (15-350 keV), at ~21 sec after the trigger.
