GCN Circular 36641

S. Dalessi (UAH) and C. Meegan (UAH) report on behalf of
the Fermi Gamma-ray Burst Monitor Team:

"At 11:01:14.31 UT on 07 June 2024, the Fermi Gamma-ray Burst Monitor (GBM)
triggered and located GRB 240607A (trigger 739450879/240607459),
which was also detected by AstroSat (G. Waratkar et al. 2024, GCN 36638
Not found
 
 
) and INTEGRAL/SPI-ACS (trigger #10733). The final localization can be found in GCN 36634
Not found
 
 
 as well as the notice of a bright burst (S. Dalessi et al. 2024, GCN 36637
Not found
 
 
).

The angle from the Fermi LAT boresight is 109 degrees.

The GBM light curve three pulses with a duration (T90)
of about 20.2 s (50-300 keV). The time-averaged spectrum
from T0+0.002 to T0+27.136 s is best fit by
a Band function with Epeak = 247 +/- 4 keV,
alpha = -0.92 +/- 0.01, and beta = -2.69 +/- 0.07.

The event fluence (10-1000 keV) in this time interval is
(9.2 +/- 0.5)E-05 erg/cm^2. The 1-sec peak photon flux measured
starting from T0+11 s in the 10-1000 keV band is 95.8 +/- 0.8 ph/s/cm^2.

The spectral analysis results presented above are preliminary;
final results will be published in the GBM GRB Catalog:
