Circular_text	TITLE: GCN CIRCULAR NUMBER: 33168 SUBJECT: GRB 230114A: Fermi GBM Final Real-time Localization DATE: 23/01/14 17:09:30 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM The Fermi GBM team reports the detection of a likely LONG GRB At 16:59:13 UT on 14 Jan 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230114A (trigger 695408358.896514 / 230114708). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 236.3, Dec = 3.9 (J2000 degrees, equivalent to J2000 15h 45m, 3d 53'), with a statistical uncertainty of 2.5 degrees. The angle from the Fermi LAT boresight is 80.0 degrees.

Vertat (FEL ZCU) -- the VZLUSAT-2/GRB payload collaboration. The long-duration GRB 230114A (Fermi/GBM detection: The Fermi GBM team, GCN Circ. 33168; INTEGRAL/SPI-ACS detection peak at 2023-01-14 ~16:59:14 UT) 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 GRB detector unit no. 1 and the detection was confirmed at the peak time 2023-01-14 16:59:17 UTC. The T90 duration was measured to be 5 s with the light curve resolution of 1 s. The significance during T90 reaches 6.7 sigma. The light curve obtained by VZLUSAT-2 is available here: https://vzlusat2.konkoly.hu/static/share/GRB230114A_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 constellation of CubeSats (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.
