We observed the field of GRB 200524A (Fana Dirirsa et al., GCN 27797) with the 3.6m Devasthal Optical Telescope (DOT) located in Devasthal, India on 2020-05-24T19:18:00 (UT) using the recently commissioned ADFOSC instrument.  We observed a sequence of 300 sec images in g, r and i bands.  We clearly detect the optical transient discovered by ZTF  (Ho et al., GCN 27799) and also reported by Kumar et al. (GCN 27800) and Rumyantsev et al. (GCN 27802).   In the first r band image the afterglow has a r band magnitude of 21.1+/-0.03.  Further processing of the data is in progress.
