GRB 241030B: AKO Optical Afterglow Detection

We observed the field of GRB 241030B detected by Fermi/GBM (Fermi GBM team, GCN 37980), Swift/BAT (Klingler et al., GCN 37981), and SVOM/ECLAIRs (Zhao et al., GCN 37984), with our 0.36m f/7.7 robotic telescope. The observation started on 30 October 2024 at 18:58 (UT), 24 minutes from the trigger. We obtained multiple 180-sec exposures in Ic filter. We detected the optical afterglow at: R.A. (J2000): 03:23:10.26 Dec. (J2000): +34:26:50.1 Our detection is consistent with the results of (Fu et al., GCN 37985). The following observation was calculated using Atlas catalogue as a reference: ---------------------------------------------------------------------------- - ObsTime (mid), Exposure (sec), Filter, Mag ---------------------------------------------------------------------------- - 2024-10-30T19:08:23Z, 7x180s (stacked), Ic, 18.9 +/- 0.26 ---------------------------------------------------------------------------- - The magnitude is not corrected for galactic extinction.
