GRB 241025A: optical photometry from Konkoly

We report detection and photometry of the optical afterglow of GRB 241025A (Ambrosi et al., GCN 37859; Fermi GBM team GCN 37860; Wang et al. GCN 37863) taken with the RC80 robotic telescope at Piszkesteto Station of Konkoly Observatory, Hungary. The observations started on 2024-10-25 16:48:09.79 UT, 15.19 hours after the trigger. 7 sets of 300 sec frames were collected through. Sloan r'- and i' bands. The optical afterglow (Jiang et al. GCN 37862; Pereyra et al. GCN 37865; SVOM/VT team GCN 37871; Abdi et al. GCN 37882; Watson et al. GCN 37889; Mohan et al. GCN 37890) was detected on the stacked frames with the following magnitudes, calibrated via nearby PS1 stars: Date UT-middle t-T0(days) Exp(s) r'(AB) i'(AB) 2024-10-25 17:18:57.70 0.65425 7x300 22.04 (0.35) 20.07 (0.17) The magnitudes above are not corrected for galactic extinction.
