Barway(IIA) report on behalf of the\nGIT team:\n\nWe observed GRB 210208A detected by INTEGRAL (S. Mereghetti et. al., GCN\n#29429) with 0.7m GROWTH-India Telescope (GIT). We obtained four exposures\nof 300-sec each in the r' filter. We did not detect any new source in our\nstacked image within the 2 arcmin circle around R.A.= 260.1976 deg, DEC.=\n-12.6667 deg. The obtained upper limit follows as:\n\n-----------------------------------------------------------------\n\n JD (mid) | T_mid-T0(hrs) | Exposure | Filter | Lim_mag (5-sigma) |\n\n-----------------------------------------------------------------\n\n 2459254.51368 | 10.78 | 300*4 (stacked) | r' | > 21.1 |\n\n-----------------------------------------------------------------\n\nThe magnitudes are calibrated against PanSTARRS (Flewelling et al., 2018)\nand not corrected for galactic extinction.\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).",
