Vadawale (PRL) report on behalf of the AstroSat CZTI collaboration:\n\nAnalysis of AstroSat CZTI data showed the detection of a long GRB 190203A, which was also detected by Swift (Lien A. Y. et al., GCN Circ 23845) and Konus-Wind (Frederiks D. et al., GCN Circ 23859).\n\nThe source was clearly detected in the 20-200 keV energy range. The light curve shows multiple peaks of emission with the strongest peak at 15:44:14.0 UT. The measured peak count rate is 314 cts/s above the background in the combined data of four quadrants, with a total of 387 cts. The local mean background count rate was 340 cts/s. Using cumulative rates, we measure a T90 of 46.45 s.\n\nIt was also clearly detected in the CsI anticoincidence (Veto) detector in the 100-500 keV energy range.\n\nCZTI GRB detections are reported regularly on the payload site at http://astrosat.iucaa.in/czti/?q=grb. CZTI is built by a TIFR-led consortium of institutes across India, including VSSC, ISAC, IUCAA, SAC and PRL. The Indian Space Research Organisation funded, managed and facilitated the project.",
