N. J. Klingler (GSFC/UMBC/CRESSTII), K. L. Page (U Leicester) and
D. M. Palmer (LANL) report on behalf of the Neil Gehrels Swift
Observatory Team:

At 06:01:09 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 240624A (trigger=1238732).  Swift did not slew to the location
due to an observing constraint.  The BAT on-board calculated location is 
RA, Dec 102.444, -6.543 which is 
   RA(J2000) = 06h 49m 47s
   Dec(J2000) = -06d 32' 36"
with an uncertainty of 3 arcmin (radius, 90% containment, including 
systematic uncertainty).  The BAT light curve showed a complex
structure with a duration of about 5 sec.  The peak count rate
was ~2200 counts/sec (15-350 keV), at ~1 sec after the trigger. 

Due to a Sun observing constraint, Swift cannot slew to the BAT
position until 10:01 UT on 2024 August 15. There will thus be no XRT or
UVOT data for this trigger before this time.

Please contact the BA by email if you require additional information
regarding Swift followup of this burst. In extremely urgent cases, after
trying the Burst Advocate, you can contact the Swift PI by phone (see
