Klunko (ISTP) report on\nbehalf of the IKI GRB FuN collaboration:\n\nWe performed optical observations of the field of EP250111a (Zhao et. al,\nGCN 38905; Kennea et. al, GCN 38910) in the R filter with the 1.5-meter\nAZT-33IK telescope of the Sayan Solar Observatory (Mondy). The observations\nstarted on 2025-01-11 11:57 UT, i.e. ~0.46 days since trigger. We detect\nthe optical source proposed by Fu et. al, GCN 38906 as an optical transient\nof EP250111a. Preliminary photometry of the source is the following:\n\nDate UT start t-T0 Exp. Filter OT Err. UL(3sigma)\n(mid, days) (s)\n2025-01-11 11:57:42 0.46301 51*70 R 21.20 0.15 21.4\n",
