Cenko (NASA/GSFC)\n\nWe observed the field of EP261105a detected by Einstein Probe (Guo et al., GCN 46155; Guo et al. 46168) in H and Y filters with PRIME. Observations started ~12h after the trigger.\n\nAt the position of the candidate optical afterglow reported by SVOM/VT (Ma et al., GCN 46160) we do not detect any new source down to H>20.3 AB (3-sigma), calibrated Using Two Micron All Sky Survey (2MASS) nearby stars and not corrected for galactic extinction.\n\nPRIME is a 1.8m telescope with 1.56 square degree FOV (0.5 arcsec/pixel) located in Sutherland, South Africa at the South African Astronomical Observatory (SAAO) (Kutyrev et al. 2023, Yama et al. 2023, Durbak et al. 2024).\nWe thank the Osaka University observers at PRIME and the staff at SAAO for their support with these observations.",
