At 07:14:48 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 190511 ***A*** (trigger=903158). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 126.436, -20.242 which is
RA(J2000) = 08h 25m 45s
Dec(J2000) = -20d 14' 30"
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 ~3039 counts/sec (15-350 keV), at ~0 sec after the trigger.
