Anshika Gupta (ARIES), Kuntal Misra (ARIES), Karan Dogra(ARIES) and Dimple (CMI) report:
We observed the field of GRB 240502A detected by Integral (GCN 36369) using the 1.3m Devasthal Fast Optical Telescope (DFOT) located at the Devasthal observatory of Aryabhatta Research Institute of observational sciencES (ARIES), Nainital, India. The observation started on 2024-05-04 at 14:29:05 UTC. Multiple frames of 300 sec exposure were acquired in the R band. We do not detect the optical afterglow within the Intergral uncertainty circle (GCN 36369) upto 4-sigma limit in the stacked image down to a limiting magnitude of 22.4. The photometric calibration is performed using the standard stars from the USNO-B1.0 catalog.
