    At 16:13:08 UT, the Swift Burst Alert Telescope (BAT) triggered and
    located GRB 220305 ***A*** (trigger=1095215).  Swift slewed immediately to the burst.
    The BAT on-board calculated location is 
    RA, Dec 107.584, -37.708 which is 
       RA(J2000) = 07h 10m 20s
       Dec(J2000) = -37d 42' 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 ~1449 counts/sec (15-350 keV), at ~0 sec after the trigger.
