At 12:19:02 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 240306 ***A*** (trigger=1218967). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 299.313, +35.229 which is
RA(J2000) = 19h 57m 15s
Dec(J2000) = +35d 13' 46"
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 ~1007 counts/sec (15-350 keV), at ~6 sec after the trigger.
