    At 16:18:51 UT, the Swift Burst Alert Telescope (BAT) triggered and
    located GRB 220117 ***A*** (trigger=1093592).  Swift slewed immediately to the burst.
    The BAT on-board calculated location is 
    RA, Dec 91.578, -28.410 which is 
       RA(J2000) = 06h 06m 19s
       Dec(J2000) = -28d 24' 35"
    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 ~1246 counts/sec (15-350 keV), at ~15 sec after the trigger.
