Kapanadze (AbAO) report on behalf of GRB IKI FuN: We observed the field of GRB 220107A till now detected by GBM/Fermi (the Fermi/GBM team, GCN 1399; Kunzweiler et al. GCN 31400) and Swift (DeLaunay et al. GCN 31402) with AS-32 telescope of Abastumani observatory (AbAO) and K-800 telescope of Mnt. Terskol observatory. The optical afterglow (Hosokawa et al. GCN 31413; Siegel et al. GCN 31415; Zhu et al. GCN 31416) is detected in stacked images. Preliminary photometry of the afterglow is following. Date UT start t-T0 Filter Exp.

Despite the galaxy is unlikely to be the host galaxy of GRB 220107A, it might affect photometry of the afterglow in a crude plate scale images.
