S. Dichiara (PSU), R. Gupta (NASA GSFC) and D. M. Palmer (LANL) report
on behalf of the Neil Gehrels Swift Observatory Team:

At 02:02:22 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 240805A (trigger=1246907).  Swift slewed immediately to
the burst but the observations was cut short almost immediately
after the end of slew due to an observing constraint. 
The BAT on-board calculated location is 
RA, Dec 190.911, -53.622 which is 
   RA(J2000) = +12h 43m 39s
   Dec(J2000) = -53d 37' 17"
with an uncertainty of 3 arcmin (radius, 90% containment, including 
systematic uncertainty).  The BAT light curve is not immediately
available.  However, the original BAT trigger shows an excess
of 3.3k counts in 1.024 s (25-100 keV) at the time of the trigger. 

The XRT and UVOT observations were only a few seconds long, so
X-ray and optical positions and lightcurves will not be
available until the GRB comes out of constraint around 02:58 UT. 

Burst Advocate for this burst is S. Dichiara (sbd5667 AT psu.edu). 
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
Swift TOO web site for information: http://www.swift.psu.edu/)
