COMMENTS: SWIFT-BAT GRB Coordinates.
COMMENTS: This Notice was delayed by more than 60 sec past the end of the trigger integration interval;
COMMENTS: probably due to it occurring during a Malindi downlink session.
COMMENTS: This is a rate trigger.
COMMENTS: A point_source was found.
COMMENTS: This does not match any source in the on-board catalog.
COMMENTS: This does not match any source in the ground catalog.
COMMENTS: This is a GRB.
COMMENTS: Since the IMAGE_SIGNIF is less than 7 sigma, this is a questionable detection.

At 21:30:20 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 240601 ***A*** (trigger=1232465). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 108.731, -6.206 which is
RA(J2000) = 07h 14m 55s
Dec(J2000) = -06d 12' 20"
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 ~1054 counts/sec (15-350 keV), at ~4 sec after the trigger.
