TITLE: GCN CIRCULAR NUMBER: 34910 SUBJECT: GRB 231024A: AKO Optical Counterpart Candidate DATE: 23/10/30 12:04:57 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 Dalya Akl, Ilmah Abdi, and Nidhal Guessoum (American University of Sharjah, UAE), report: We observed the field of GRB 231024A (Fermi GBM Team, GCN 34876; Gompertz et al., GCN 34878; Iglesias-López et al., GCN 34881; Saccardi et al., GCN 34882; Scotton et. al., GCN 34885) with our 0.36m f/7.7 robotic telescope. The observation was done on 29 October 2023 from 17:31 UT to 19:14 UT, 5.21 days after the trigger. We obtained 32x180 sec. images using (Ic) filter. We detected the optical afterglow candidate of GRB 231024A in our stacked images at the coordinates (J2000.0): R.A.: 00:55:07.28, Dec.: -15:15:19.6, which is consistent with the observation of (Gompertz et al., GCN 34878). The following magnitude was calculated using the Atlas catalogue as a reference: ----------------------------------------------------------------------------- ObsTime (mid), Exposure (sec), Filter, Mag, MagRMS ----------------------------------------------------------------------------- 2023-10-29T18:24:01Z, 32x180s (stacked), Ic, 18.3, 0.16 ----------------------------------------------------------------------------- The magnitude is not corrected for galactic extinction.
