TITLE: GCN CIRCULAR NUMBER: 42087 SUBJECT: GRB 251002A: AKO Early Optical Afterglow Detection DATE: 25/10/03 11:28:22 GMT FROM: Mohammad Odeh at Al Khatim Observatory M44 <mshodeh@gmail.com> Mohammad Odeh (Al-Khatim Observatory, AKO, operated by the International Astronomical Center in Abu Dhabi, UAE), and Shaikha Alshamsi, and Nidhal Guessoum (American University of Sharjah, UAE), report: We observed the field of GRB 251002A detected by SVOM/ECLAIRs (Saccardi et al., GCN 42060), using our 0.36m f/7.7 robotic telescope. The observation session began on 02 October 2025 at 21:08 UT, with a midpoint at 21:44 UT, approximately 1.49 hours after the trigger. We obtained 20 exposures of 180 seconds each using the Ic filter. The optical afterglow was detected at: R.A. (J2000): 00:55:38.0 Dec. (J2000): -05:34:01.9 Our detection is consistent with the results of (Palmerio et al., GCN 42061), (Turpin et al., GCN 42062), (Jelinek et al., GCN 42063), (Perez-Fournon et al., GCN 42064), (Moskvitin et al., GCN 42065), (Perez-Garcia et al., GCN 42066), (Lipunov et al., GCN 42067), (Saccardi et al., GCN 42076), (Mandrakas et al., GCN 42077), (Cao et al., GCN 42078), (Schneider et al., GCN 42080), (Pankov et al., GCN 42081) and (Leonini et al., GCN 42082). The following observation was calculated using the Atlas catalogue as a reference: ---------------------------------------------------------------------------- ObsTime (mid), Exposure (sec), Filter, Mag ---------------------------------------------------------------------------- 2025-10-02T21:44:20Z, 20x180s (stacked), Ic, 18.57 +/- 0.27 ---------------------------------------------------------------------------- The magnitude is not corrected for galactic extinction.
