Bhattacharya (IUCAA) \non\nbehalf of the AstroSat LAXPC and CZTI collaboration report:\n\nAnalysis of AstroSat LAXPC and CZTI data showed the detection of a long \nGRB 2002010A.\n\nThe source was clearly detected in the 3-400 keV energy range. The light \ncurve showed\nmultiple peaks of emission with the strongest peak at 2020-02-10 \n08:03:40.00 UT. The\nmeasured peak count rate above the background associated with the burst \nis 354 +/- 29 cts/s\nin LAXPC10 and 197 +/- 21 in LAXPC20, with a total of 5524 +/- 143 cts \nin LAXPC10 and\n3384 +/- 99 in LAXPC20. LAXPC20 has a nominal energy range of 3-100 keV \nbut due to lower\ngain in LAXPC10 the energy range is about 30-400 keV. The background \nsubtracted light curve\nwith 1 sec time-bin in LAXPC detectors is available at the web-site:\n\n  https://www.tifr.res.in/~astrosat_laxpc/grb200210lc.jpg\n\nThe measured peak count rate associated with the burst in CZTI is 288 \n+/- 29 cts/s above\nthe background in the combined data of four quadrants, with a total of \n6338 +/- 67 cts.\nThe local mean background count rate was 533 +/- 15 cts/s. Using \ncumulative rates, we\nmeasure a T90 of 29.2 +/- 0.01 s. CZTI operates in the energy range of \n40-200 keV. It was\nalso clearly detected in the CsI anticoincidence (Veto) detector in the \n100-500 keV energy\nrange.\n\nCZTI GRB detections are reported regularly on the payload site at\nhttp://astrosat.iucaa.in/czti/?q=grb.\n\nLAXPC is built by TIFR in collaboration with the Indian Space Research \nOrganisation.\nCZTI is built by a TIFR-led consortium of institutes across India, \nincluding VSSC, ISAC,\nIUCAA, SAC and PRL. The Indian Space Research Organisation funded, \nmanaged and\nfacilitated the project.",
