GCN #29233) with Aries\nDevasthal Faint Object Spectrograph and Camera (ADFOSC) mounted on the 3.6m\nDevasthal Optical Telescope (DOT). The observations started on 2021-01-13\nat 19:52:50 UT (9.374 days after the burst). We obtained a set of\nconsecutive images with short exposure times to avoid saturation from the\nnearby bright star. We do not detect any optical counterpart upto a\nmagnitude limit of 23.2 in the stacked image.",
