GCN #29607)  with 1.3m Devasthal Fast Optical\nTelescope (DFOT) at Devasthal observatory of Aryabhatta Research\nInstitute of observational sciencES (ARIES), India. We took\nobservations in B,V,R,I bands. We detect the optical afterglow with a\nmagnitude of 20.24 +- 0.13 in R-band at 9.8 hrs after the burst.\nFurther observations are ongoing with 1.3m DFOT.\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.",
