At 17:49:01 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 190611 ***A*** (trigger=907950). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 324.769, -56.082 which is
RA(J2000) = 21h 39m 05s
Dec(J2000) = -56d 04' 54"
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 ~1132 counts/sec (15-350 keV), at ~1 sec after the trigger.
