TITLE: GCN CIRCULAR NUMBER: 37277 SUBJECT: GRB 240825A: AKO Optical Afterglow Detection DATE: 24/08/25 17:37:42 GMT FROM: Mohammad Odeh at Al Khatim Observatory M44 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 240825A detected by Fermi (Fermi GBM team, GCN 37273) and Swift (Gupta et al., GCN 37274), with our 0.36m f/7.7 robotic telescope. The observation started on 25 August 2024 at 16:48 (UT), 55 minutes from the trigger. We obtained multiple 180-sec exposures in Ic filter. We clearly detected the optical afterglow at: R.A. (J2000): 22:58:17.3 Dec. (J2000): +01:01:36.4 Our detection is consistent with the results of (Jiang et al., GCN 37275; and Dutton et al., GCN 37276). The following observation was calculated using Atlas catalogue as a reference: ---------------------------------------------------------------------------- - ObsTime (mid), Exposure (sec), Filter, Mag ---------------------------------------------------------------------------- - 2024-08-25T17:08:55Z, 13 x 180s (stacked), Ic, 17.6 +/- 0.16 ---------------------------------------------------------------------------- - The magnitude is not corrected for galactic extinction.
