Vertat (FEL ZCU)  -- the VZLUSAT-2/GRB payload collaboration.\n\nThe long-duration GRB 240710B (Fermi/GBM detection: trigger no. 742317942; Konus/Wind detection trigger at 2024-07-10 15:25:41.692 UTC; GRBAlpha detection: GCN 36953) was detected by the GRB detector on board of the VZLUSAT-2 3U CubeSat (https://www.vzlusat2.cz/en/).\n\nThe data acquisition was performed by the GRB detector unit no. 1. The detection was confirmed at the peak time 2024-07-10 15:25:37 UTC. The T90 duration is 5 s and the significance during T90 reaches 27 sigma.\n\nThe light curve obtained by VZLUSAT-2 is available here:\nhttps://vzlusat2.konkoly.hu/static/share/GRB240710B_GCN_VZLUSAT2.pdf\n\nAll VZLUSAT-2 detections are listed at: https://monoceros.physics.muni.cz/hea/VZLUSAT-2/\nThe 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.\n\n",
