Vadawale (PRL) report on behalf of the AstroSat\nCZTI collaboration: \n\nAnalysis of AstroSat CZTI data with the CIFT framework (Sharma et al.,\n2021, JApA, 42, 73) showed detection of a short GRB 220323A which was\nalso detected by Fermi - GBM (GCN 31782) and AGILE/MCAL (Ursi et al.,\nGCN 31784). \n\nThe source was clearly detected in the 20-200 keV energy range. The\nlight curve peaks at 2022-03-23 12:10:10.55 UT. The measured peak count\nrate associated with the burst is 1120 (+888, -4) counts/s above the\nbackground in the combined data of three quadrants, with a total of 141\n(+48, -50) counts. The local mean background count rate was 386 (+13,\n-34) counts/s. Using cumulative rates, we measure a T90 of 0.32 (+0.22,\n-0.15) s. \n\nIt was also detected in the CsI anticoincidence (Veto) detector in the\n100-500 keV energy range. \n\nCZTI GRB detections are reported regularly on the payload site at\nhttp://astrosat.iucaa.in/czti/?q=grb [1]. CZTI is built by a TIFR-led\nconsortium of institutes across India, including VSSC, ISAC, IUCAA, SAC,\nand PRL. The Indian Space Research Organisation funded, managed, and\nfacilitated the project. \n\nLinks:\n------\n[1] http://astrosat.iucaa.in/czti/?q=grb",
