At 19:22:55 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 240203 ***A*** (trigger=1212791). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 300.147, +35.176 which is
RA(J2000) = 20h 00m 35s
Dec(J2000) = +35d 10' 33"
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 ~929 counts/sec (15-350 keV), at ~8 sec after the trigger.
