Anupama(IIA), S.\nBarway(IIA), report on behalf of the GROWTH-India collaboration:\n\nWe observed GRB 201017A reported by Fermi GBM Team (GCN #28665) and Swift-BAT\n(A. D'Ai et al., GCN #28666; also see:- V. Lipunov et al., GCN #28667; M.R.\nGoad et al., GCN #28671; L. P. Xin et al., GCN #28672; S. Poolakkil et al.,\nGCN #28675; J.A. Kennea et al., GCN #28678; S. Belkin et al., GCN #28679) with\n0.7m GROWTH-India telescope. The field was observed in the SDSS r��� filter\nstarting at 2020-10-17T12:54:58.41 UT i.e. ~3.13 hrs after the event\ndetection by Swift-BAT. We did not find any new source in the stacked image\nof 10*300 sec exposure, within an uncertainty region of 2.6 arcsec around RA\n(J2000): 02h 26m 28.82s, Dec (J2000): +66d 40' 43.6\" (GCN 28671) up to r��� >\n21.01 mag (5-sigma), calibrated against PanSTARRs PS1 data release,\n(Flewelling et al., 2018). Assuming a typical power-law decay, this upper\nlimit is consistent with the r���=22.9 mag detection by Belkin et al (GCN #\n28679).\n\nThe GROWTH India Telescope (GIT) is a 70-cm telescope with a 0.7-degree\nfield of view, set up by the Indian Institute of Astrophysics and the\nIndian Institute of Technology Bombay with support from the Indo-US Science\nand Technology Forum (IUSSTF) and the Science and Engineering Research\nBoard (SERB) of the Department of Science and Technology (DST), Government\nof India (https://sites.google.com/view/growthindia/). It is located at the\nIndian Astronomical Observatory (Hanle), operated by the Indian Institute\nof Astrophysics (IIA).",
