Vadawale (PRL) report on behalf of the AstroSat CZTI collaboration:\n\nAnalysis of AstroSat CZTI data with the CIFT framework (Sharma et al., 2021, JApA, 42, 73) showed the detection of a short GRB 230604A which was also detected by KONUS-Wind (IPN_RAW Notices).\n\nThe source was clearly detected in the 20-200 keV energy range. The light curve peaks at 2023-06-04 05:53:48.0 UTC. The measured peak count rate associated with the burst is 669.5 (+184.9, -93.0) counts/s above the background in the combined data of all quadrants, with a total of 357 (+164, -169) counts. The local mean background count rate was 431.1 (+12.1, -15.6) counts/s. Using cumulative rates, we measure a T90 of 1.24 (+0.99, -0.73) s.\n\nThe source was also detected in the CsI anticoincidence (Veto) detector in the 100-500 keV energy range.\n\nCZTI is built by a TIFR-led consortium of institutes across India, including VSSC, URSC, IUCAA, SAC, and PRL. The Indian Space Research Organisation funded, managed, and facilitated the project.\n\nCZTI GRB detections are reported regularly on the payload site at:\nhttp://astrosat.iucaa.in/czti/?q=grb\n",
