Circular_text TITLE: GCN CIRCULAR NUMBER: 33225 SUBJECT: GRB 230126A: Fermi GBM Final Real-time Localization DATE: 23/01/26 18:31:09 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM The Fermi GBM team reports the detection of a likely LONG GRB At 18:20:44 UT on 26 Jan 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230126A (trigger 696450049.448062 / 230126764). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 96.9, Dec = -27.0 (J2000 degrees, equivalent to J2000 06h 27m, -27d 00'), with a statistical uncertainty of 11.8 degrees. The angle from the Fermi LAT boresight is 91.0 degrees.

Vertat (FEL ZCU) -- the VZLUSAT-2/GRB payload collaboration. The long duration GRB 230126A (Fermi/GBM detection: GCN Circ. 33225) 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. 0 and the detection was confirmed at the peak time 2023-01-26 18:20:46 UTC. The T90 duration was measured to be 14 s with the light curve resolution of 1 s. The significance during T90 reaches 5.1 sigma. The light curve obtained by VZLUSAT-2 is available here: https://vzlusat2.konkoly.hu/static/share/GRB230126A_GCN_VZLUSAT2.pdf 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.
