Stanzin (IIA)\nreport on behalf of the GROWTH-India collaboration:\n\nWe mistakenly reported the wrong observation time in our previous GCN\n27800. We deeply apologize for the confusion caused.\n\nHere is the corrected GCN:-\n-----------------------------------------------------------------\n\nWe followed up GRB 200524A (F. F. Dirirsa et al., GCN 27797, A. Ho et al.,\nGCN 27799) with 0.7m GROWTH-India telescope. We obtained 600-sec exposures\nin SDSS g, r, i filters starting at UT 2020-05-24T16:11:57 (~11.11 hrs\nafter the burst). We detect a faint transient with magnitudes r = 20.56 +/-\n0.14 and i = 20.59 +/- 0.28 (calibrated against PanSTARRs PS1 data\nrelease, Flewelling\net al., 2018). The source position matches with the likely afterglow\ncandidate by A. Ho et al. (GCN 27799). The fading rate is approximately 3\nmagnitudes in ~9.4 hours, consistent with the fading rate reported in the\nZTF GCN. We hereby, confirm ZTF20abbiixp as the afterglow of GRB 200524A.\n\nWe obtained the following photometric results:-\n\n------------------------------------------------------------------\n\n JD(Start) | T-T0(hrs) | Filter | Mag |\n\n------------------------------------------------------------------\n\n2458994.174 | 11.11 | g | > 21.01\n\n2458994.183 | 11.33 | r | 20.56 +/- 0.14\n\n2458994.191 | 11.52 | i | 20.59 +/- 0.28\n\n------------------------------------------------------------------\n\nGiven the fast fading of the source, we encourage the followup of the\nsource. The magnitudes are 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).",
