  "body": "Anshika Gupta, Kuntal Misra (ARIES) report: \n\nWe observed the field of GRB 240615A detected by Fermi GBM (GCN #36671) and Swift/BAT-GUANO (GCN #36672) and 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 2024-06-16 at 20:07:06 UTC, i.e., ~ 26.25 hours after the trigger. 24 frames of 300 sec exposure were acquired in the R band. We do not detect the optical afterglow (earlier reported in #GCN 36676, #GCN 36680) in the stacked image down to a limiting magnitude of 22.8. The photometric calibration is performed using the standard stars from the USNO-B1.0 catalog.\n",
