  "body": "Pankaj Pawar, Anshika Gupta, Debalina Kar, Dhruv Jain and Kuntal Misra (ARIES) report:\n\nWe observed the field of EP260416a (Hu et al., GCN 44307) with the 1.3m Devasthal Fast Optical Telescope (DFOT), located at the Devasthal Observatory of the Aryabhatta Research Institute of observational sciencES (ARIES), India.\n\nThe observations began on 2026-04-20 at 15:58:17 UT, approximately ~106 hours after the trigger. We obtained a series of 300s exposures in the R filter. The frames were aligned and stacked to improve the signal-to-noise ratio. \n\nThe optical counterpart (Ducoin et al., GCN 44310; Li et al., GCN 44315; Hua et al., GCN 44318; Lee et al., GCN 44319; Zheng et al., GCN 44321; Martin-Carrillo et al., GCN 44328; Li et al., GCN 44334; He et al.

GCN 44341; Guziy et al., GCN 44351; and Ho et al., GCN 44354) was not detected in the stacked image.\n\nThe details of observations and measured upper limit are as follows:\n\nDate (UT)     Start Time    T_start-T0 (days)   Filter    Exposure (s)    Magnitude (AB)\n=======================================================================================\n2026-04-20     15:58:17         ~4.44              R        300s*13         >22.6\n\nThe magnitude is calibrated using Pan-STARRS field stars.",
