Vadawale (PRL) report on behalf of the AstroSat CZTI collaboration:\n\nAnalysis of AstroSat CZTI data showed the detection of a GRB 190501B.\n\nThe source was clearly detected in the 40-200 keV energy range. The light curve shows multiple peaks of emission with strongest peak at 02:11:50.5 UT. The measured peak count rate associated with the burst is 88 cts/s above the background in the combined data of four quadrants, with a total of 410 cts. The local mean background count rate was 408 cts/s. Using cumulative rates, we measure a T90 of  12.5s.\n\nIt was also 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.\n\n[GCN OPS NOTE(23may19): See Circ 24374 that corrects the name in the Subject line from \"BA\" to \"B\".]",
