Stanzin (IIA) report on behalf of the GROWTH collaboration:\n\nWe observed the field of GRB190604B reported by K. L. Page et al., GCN\n24742 at 2019-06-04 and 20:03:18.675 UT with the 0.7m GROWTH-India\ntelescope. We took 2 exposures of 600 seconds each in r filter. No source\nwas found within an uncertainty region of 3.6 arcseconds to RA(J2000) = 19h\n50m 09.13s, Dec(J2000) = -32d 58' 35.9\" (K. L. Page et al.,GCN 24742).\n\nWe obtained the following upper limits:\n\n------------------------------------------------------------------\n\n JD(Start)| Exposure(sec) | Filter | lim_Mag |\n\n------------------------------------------------------------------\n\n2458639.335 | 600 | r | 20.33|\n\n2458639.342 | 600 | r | 19.93|\n\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\nof India (https://sites.google.com/view/growthindia/).
