  "body": "Mohammad Odeh (Al-Khatim Observatory, AKO, operated by the International\nAstronomical Center in Abu Dhabi, UAE), and Nidhal Guessoum (American\nUniversity of Sharjah, UAE), report:\n\nWe observed the field of GRB 250502A detected by SVOM (Wang et al., GCN\n40313), using our 0.36m f/7.7 robotic telescope. The observation session\nbegan on 02 May 2025 at 15:40 UT, with a midpoint at 16:43 UT, approximately\n8 hours after the trigger.\n\n \n\nWe obtained multiple 180-second exposures using the Ic filter. The optical\nafterglow was marginally detected at:\n\nR.A. (J2000): 13:46:05.4 \n\nDec. (J2000): -10:45:32.4\n\n \n\nOur detection is consistent with the results of (Rakotondrainibe et al., GCN\n40315; An et al., GCN 40319; Li et al., GCN 40320; Ghosh et al., GCN 40322;\nde Ugarte Postigo et al., GCN 40328; Pérez-Fournon et al., GCN 40330).\n\n \n\n \n\nThe following observation was calculated using the Atlas catalogue as a\nreference:\n\n----------------------------------------------------------------------------\n-\n\nObsTime (mid), Exposure (sec), Filter, Mag\n\n----------------------------------------------------------------------------\n-\n\n2025-05-02T16:43:29Z, 40 x 180s (stacked), Ic, 19.74 +/- 0.31\n\n----------------------------------------------------------------------------\n-\n\nThe magnitude is not corrected for galactic extinction.\n\n",
