  "body": "Mohammad Odeh (Al-Khatim Observatory, AKO, operated by the International\nAstronomical Center in Abu Dhabi, UAE), and Shaikha Alshamsi, and Nidhal\nGuessoum (American University of Sharjah, UAE), report:\n\nWe observed the field of GRB 251002A detected by SVOM/ECLAIRs (Saccardi et\nal., GCN 42060), using our 0.36m f/7.7 robotic telescope. The observation\nsession began on 02 October 2025 at 21:08 UT, with a midpoint at 21:44 UT,\napproximately 1.49 hours after the trigger.\n\nWe obtained 20 exposures of 180 seconds each using the Ic filter. The\noptical afterglow was detected at:\nR.A. (J2000): 00:55:38.0\nDec. (J2000): -05:34:01.9\n\nOur detection is consistent with the results of (Palmerio et al., GCN\n42061), (Turpin et al., GCN 42062), (Jelinek et al., GCN 42063),\n(Perez-Fournon et al., GCN 42064), (Moskvitin et al., GCN 42065),\n(Perez-Garcia et al., GCN 42066), (Lipunov et al., GCN 42067), (Saccardi et\nal., GCN 42076), (Mandrakas et al., GCN 42077), (Cao et al., GCN 42078),\n(Schneider et al., GCN 42080), (Pankov et al., GCN 42081) and (Leonini et\nal., GCN 42082).\n\nThe following observation was calculated using the Atlas catalogue as a\nreference:\n----------------------------------------------------------------------------\nObsTime (mid), Exposure (sec), Filter, Mag\n----------------------------------------------------------------------------\n2025-10-02T21:44:20Z, 20x180s (stacked), Ic, 18.57 +/- 0.27\n----------------------------------------------------------------------------\n\nThe magnitude is not corrected for galactic extinction.\n\n",
