At 07:52:06 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 240730 ***A*** (trigger=1245636). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 37.829, +59.074 which is
RA(J2000) = 02h 31m 19s
Dec(J2000) = +59d 04' 27"
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 ~1093 counts/sec (15-350 keV), at ~6 sec after the trigger.
