At 06:57:43 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 240603 ***A*** (trigger=1232755). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 36.054, -50.944 which is
RA(J2000) = 02h 24m 13s
Dec(J2000) = -50d 56' 38"
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 ~6781 counts/sec (15-350 keV), at ~7 sec after the trigger.
