James DeLaunay (PSU), Aaron Tohuvavohu (U Toronto), Samuele Ronchini (PSU), Gayathri Raman (PSU), Jamie A. Kennea (PSU), Tyler Parsotan (NASA GSFC) report:
Swift/BAT did not localize GRB 240824B onboard (T0: 2024-08-24T13:11:16.7 UTC, Fermi Trigger 746197881, MAXI GCN 37261).
In a ground search of a 10 s event file, available due to a subthreshold trigger onboard. The GRB was detected at a S/N of 8.5 in a single 10 s image. The duration in the rates data is ~16 s.
The BAT position is
RA, Dec = 17.835, +2.620 deg which is
RA(J2000) = 01h 11m 20.4s
Dec(J2000) = +02d 37′ 12.0″
with an estimated uncertainty of 3 arcmin radius.
XRT and UVOT follow-up has been requested.
Results of follow-up observations will be reported in future circulars.
