Evans et al., GCN #28385) with 0.7m GROWTH-India telescope.\nThe field was observed in the SDSS r filter starting at\n2020-09-07T20:59:05.36 UT i.e. ~2.1 hrs after the event detection by\nSwift-BAT. We didn���t find any new source in stacked image of 7*500 sec\nexposure, within an uncertainty region of 2.2 arcsec around RA(J2000) =\n05:56:06.93, Dec(J2000)= +06:54:22.8 (GCN 28385) up to r > 20.83 mag\n(5-sigma)(Calibrated against PanSTARRs PS1 data release, Flewelling et al.,\n2018)\n\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\n\nof India (https://sites.google.com/view/growthindia/).
