At 11:06:30 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 240311 ***A*** (trigger=1219546). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 299.936, +34.537 which is
RA(J2000) = 19h 59m 45s
Dec(J2000) = +34d 32' 13"
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 ~1046 counts/sec (15-350 keV), at ~1 sec after the trigger.
