GCN 32549) was \ndetected by a GRB detector on board of the VZLUSAT-2 3U CubeSat \n(https://www.vzlusat2.cz/en/).\n\nThe data acquisition was performed by the GRB detector unit no. 1. The \n9.1 sigma detection was confirmed at 2022-09-12 00:50:23 UTC. The GRB \nhas the T90 duration of 36 s.\n\nThe light curve obtained by VZLUSAT-2 is available here:\nhttps://vzlusat2.konkoly.hu/static/share/GRB220912A_GCN_VZLUSAT2.pdf\n\nGRB detectors on VZLUSAT-2 are a demonstration payload for a future \nCubeSats constellation (Werner et al. Proc. SPIE 2018). Two GRB modules \nof VZLUSAT-2 are placed in a perpendicular manner and each consists of a \n75 x 75 x 5 mm3 CsI scintillator read out by a SiPM array, covering the \nenergy range from ~30 keV to ~1000 keV. VZLUSAT-2 was launched on 2022 \nJanuary 13 from Cape Canaveral.",
