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).
