Vadawale (PRL) report on behalf of the AstroSat CZTI collaboration:\n\nAnalysis of AstroSat CZTI data showed clear detection of GRB161129A (Swift BAT detection: S. Barthelmy et al., GCN Circ. 20210) in the 40-200 keV energy \nrange. The light curve shows multiple peak structure at 07:12:06.0 UT, after 27 secs of the Swift Trigger. The measured peak count rate is 170.205 counts/sec \nabove the background in combined data of four quadrants, with a total of 2160.0 counts. The local mean background count rate was 377.79 counts/sec. Using \ncumulative rates, we measure a T90 of 34.06 secs.\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\nacross India, including VSSC, ISAC, IUCAA, SAC and PRL. The Indian Space Research Organisation funded, managed and facilitated the project.\n\n-------------------------\nVidushi\nJRF\nIUCAA, Pune\nE-mail: vidushi@iucaa.in\n-------------------------"
