We report photometry of Type Ia SN 2025qpk (TNSTR-2025-2620, TNSCR-2025-2624) gathered with the OAUNI 51cm telescope (arXiv:1512.03104) at Huancayo Observatory, Peru. CCD imaging in R filter was performed on two consecutive nights under non-photometric conditions with airmasses lower than 1.3. The integration time was 60x20s=1200s for all observations. Our measurements yielded:

UCAC4 field stars were used for the zero point calibration. Our observations are ~17 days after the discovery (TNSTR-2025-2620). The OAUNI project is supported by UNI, TWAS, IGP and ProCiencia-Concytec (Convenio 133-2020 Fondecyt).
