We report multicolor photometric observations of the Type II supernova SN 2026fov (TNSTR-2026-1076, TNSCR-2026-1145), obtained using the OAUNI 51cm telescope (arXiv:1512.03104) at the Huancayo Observatory, Peru. CCD imaging was conducted through V, R, and I filters across two epochs under non-photometric conditions, with the target observed at low altitude during the final night. The total integration time for SN 2026fov was 1400s (70x20s) per filter for both epochs. Our measurements yielded:

Zero-point calibrations were performed using field stars from the UCAC4 catalog. The observations were obtained approximately 123 days post-discovery of SN 2026fov. The OAUNI project is supported by UNI (FC-PFR-21-2025), TWAS, IGP, and ProCiencia-Concytec (Convenio 133-2020).
