  "body": "Mohammad Odeh, Osama Ghannam, Anas Mohammad, Khalfan Al-Noaimy, and Sameh\nAl-Ashi, report on behalf of Al-Khatim Observatory (AKO) operated by the\nInternational Astronomical Center in Abu Dhabi, UAE:\n\nWe observed ZTF23abaanxz (AT 2023qxj) discovered by ZTF (M. L. Li et al.,\nGCN 34574) in the localization region of the Fermi GRB230827.256 (trigger\nNo 714809315), with our 0.36m f/7.7 robotic telescope. The observation was\ndone on 27 August 2023 starting from 18:12 (UT), about 12 hours after the\nGRB trigger.\n\nWe obtained multiple 180-sec exposures in Ic and R filters. We detected the\ncandidate at the position reported by (M. L. Li et al., GCN 34574) and\nconfirmed by (Swain et al., GCN 34576).\n\nThe following observations were calculated using the Atlas catalogue as a\nreference:\n-----------------------------------------------------------------------------\nObsTime (mid), t(mid) – t(0) (hours), Exposure (sec), Filter, Mag\n-----------------------------------------------------------------------------\n2023-08-27T18:31:42Z, 12.4, 13 x 180s (stacked), Ic, 18.2 +/- 0.21\n\n2023-08-27T19:19:30Z, 13.2, 16 x 180s (stacked), R, 19.1 +/- 0.23\n-----------------------------------------------------------------------------\n\nThe magnitudes are not corrected for galactic extinction.\n",
