Dirirsa et al., GCN\n27797, Evans et al., GCN 27798) with the 1.3m Devasthal Fast Optical\nTelescope (DFOT) at Aryabhatta Research Institute of Observational Sciences\n(ARIES), Nainital (India), from 2020-05-24T19:50:12 UTC (corresponding to\n~14.770 hours after\nthe burst).\n\nWe observed 5 frames each of 300 seconds in Bessell I filter. In the\nstacked image, we clearly detected the optical afterglow of GRB 200524A\n(detected by Ho et al., GCN 27799, see also Kumar et al., GCN 27800,\nRumyantsev et al., GCN 27802 and Sanwal et al., GCN 27803).\n\n\nThe observed magnitude is as follows:\n\nT_start-T0 (hours)   Start Date (UTC)    End Date (UTC)      Filter\n   Magnitudes (mag)\n---------------------------------------------------------------------------------------------------------------\n14.770          2020-05-24T19:50:12     2020-05-24T20:32:37      I\n      20.33 +- 0.07\n\n\nPhotometry is done based on the USNO-B1.0 catalog.
