Joshi (ARIES)\nreport:\n\nWe observed the afterglow (Laha et al. GCN #29444, Lipunov et al. GCN\n#29447, de Ugarte Postigo et al. GCN #29450, Breeveld & Laha, GCN\n#29457, Strausbaugh & Cucchiara, GCN #29459, Jelinek et al. GCN\n#29469,  D. A. Kann et al. GCN #29476) of the GRB 210210A (Laha et al.\nGCN #29444) with 1.3m Devasthal Fast Optical Telescope (DFOT) at\nDevasthal observatory of Aryabhatta Research Institute of\nobservational sciencES (ARIES), India. We obtained multiple images in\nR and I bands with an exposure of 180 seconds each. We detect the\noptical afterglow with a magnitude of 21.35 +- 0.07 in R-band at 0.88\ndays after the burst. Further observations are ongoing with 1.3m DFOT\nand 3.6m DOT.\n\nThe magnitude is not corrected for the Galactic extinction in the\ndirection of the burst. The photometric calibration is performed using\nthe standard stars from the USNO-B1.0 catalog.",
