    At 05:12:13 UT, the Swift Burst Alert Telescope (BAT) triggered and
    located GRB 060607 ***A*** trigger=213823).  Swift slewed immediately to the burst.
    The BAT on-board calculated location is 
    RA, Dec 329.712, -22.506 which is 
       RA(J2000) = 21h 58m 51s
       Dec(J2000) = -22d 30' 20"
    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 ~4165 counts/sec (15-350 keV), at ~181 sec after the trigger.
