Shaymanov report on behalf of UBAI team.\n\nWe observed the field of EP transient EP260610b (Wu et al., GCN 44895), with the AZT-22 1.5m telescope of the Maidanak Observatory (MAO) starting on 2026-06-10 at 20:09:52 UT. In total we obtained 6x300 s exposures in the R-band using 4kx4k CCD SNUCAM camera (Im et al., 2010). \nThe optical counterpart (Levan et al., GCN 44897; Xin et al., GCN 44900; Zhu et al., GCN 44902) is detected in the stacked frame. \n\nPreliminary photometry is the following:\nDate       MidTime  Exptime     t-T0         Filter OT    Err.
