TITLE: GCN CIRCULAR NUMBER: 42157 SUBJECT: GRB 251007A: AKO Optical Upper Limit DATE: 25/10/08 05:50:58 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), Nidhal Guessoum (American University of Sharjah, UAE), and Shaikha Alshamsi (University of Sharjah, UAE), report: We observed the field of GRB 251007A detected by Swift/BAT (Ambrosi et al., GCN 42146) and Glowbug (Cheung et al., GCN 42151), using our 0.36m f/7.7 robotic telescope. The observation session began on 07 October 2025 at 23:03 UT, with a midpoint at 23:45 UT, approximately 4.1 hours after the trigger. We did not detect any uncatalogued source down to Ic=17.8 (5-sigma), not corrected for galactic extinction, at the position reported by Swift/UVOT (Ambrosi et al., GCN 42146).
