The Fermi GBM team reports the detection of a likely SHORT GRB
At 17:11:47 UT on 10 Jul 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240710A (trigger 742324312.207884 / 240710717).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 285.3, Dec = 7.5 (J2000 degrees, equivalent to J2000 19h 01m, 7d 30'), with a statistical uncertainty of 19.1 degrees.
The angle from the Fermi LAT boresight is 101.0 degrees.

Vertat (FEL ZCU) -- the VZLUSAT-2/GRB payload collaboration.
The short-duration GRB 240710A (Fermi/GBM detection: GCN 36843) was detected by the GRB detector on board of the VZLUSAT-2 3U CubeSat (https://www.vzlusat2.cz/en/).
The data acquisition was performed by the GRB detector unit no. 1. The sub-threshold detection was confirmed at the peak time 2024-07-10 17:11:45 UTC. The T90 duration is 2 s and the significance during T90 reaches 4.6 sigma.
The light curve obtained by VZLUSAT-2 is available here:

All VZLUSAT-2 detections are listed at: https://monoceros.physics.muni.cz/hea/VZLUSAT-2/
The GRB detectors on VZLUSAT-2 are a demonstration payload for a future CubeSat constellation (Werner et al. Proc. SPIE 2018). Two GRB modules of VZLUSAT-2 are placed in a perpendicular manner and each consists of a 75 x 75 x 5 mm3 CsI scintillator read out by a SiPM array, covering the energy range from ~30 keV to ~1000 keV. VZLUSAT-2 was launched on 2022 January 13 from Cape Canaveral.

report on behalf of the SVOM team:
During the commissioning phase, the SVOM/GRM detected a short GRB 240710A during offline search at 2024-07-10T17:11:47.200 UT (T0), which was also observed by Fermi/GBM (GCN 36843).
With the event-by-event data downloaded through the X-band ground station, the light curve shows that this burst consists of a single pulse with a T90 of 1.6 +/- 0.7s.
