TITLE: GCN CIRCULAR NUMBER: 40925 SUBJECT: GRB 250702F: AKO Optical Afterglow Detection DATE: 25/07/03 18:36:05 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 Nidhal Guessoum (American University of Sharjah, UAE), report: We observed the field of GRB 250702F detected by Swift/BAT (Klingler et al., GCN 40894) and Fermi/GBM (Fermi GBM Team, GCN 40892), using our 0.36m f/7.7 robotic telescope. The observation session began on 03 July 2025 at 17:04 UT, with a midpoint at 17:42 UT, approximately 20.6 hours after the trigger. We obtained multiple 180-second exposures using the Ic filter. The optical afterglow was marginally detected at: R.A. (J2000): 14:11:44.6 Dec. (J2000): +16:44:55 Our detection is consistent with the results of (Jelinek et al., GCN 40895; Kumar et al., GCN 40896; Lipunov et al., GCN 40899; Martin-Carrillo et al., GCN 40900; Angulo et al., GCN 40907; Becerra et al., GCN 40911; Brivio et al., GCN 40913; An et al., GCN 40916; Dutton et al., GCN 40921). The following observation was calculated using the Atlas catalogue as a reference: ---------------------------------------------------------------------------- - ObsTime (mid), Exposure (sec), Filter, Mag ---------------------------------------------------------------------------- - 2025-07-03T17:42:28Z, 26 x 180s (stacked), Ic, 19.5 +/- 0.4 ---------------------------------------------------------------------------- - The magnitude is not corrected for galactic extinction.
