SGR 1935+2154: Bursting activity detected by VZLUSAT-2
Abstract
The recently active SGR 1935+2154 (Fermi-GBM detection: Malacaria et al., GCN Circ. 32737, Konus-Wind detection: Ridnaia et al., GCN Circ. 32768) was detected by the GRB detector module no. 1 on board of the VZLUSAT-2 3U CubeSat (https://www.vzlusat2.cz/en/). The list of detected SGR bursts with their significance is: Date and time in UTC SNR 2022-10-12 23:26:41 17.6 2022-10-13 02:02:43 16.5 2022-10-13 22:41:28 125 The light curves obtained by VZLUSAT-2 are available here: https://vzlusat2.konkoly.hu/static/share/SGR_1935_2154_GCN_VZLUSAT-2.pdf GRB detectors on VZLUSAT-2 are a demonstration payload for a future CubeSats 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.
