We report photometry of Type II SN 2024ggi (TNSAN-2024-100, TNSAN-2024-103) gathered with the OAUNI 51cm telescope (arXiv:1512.03104) at Huancayo Observatory, Peru. CCD imaging in R filter was performed on five consecutive nights under non-photometric conditions with airmasses lower than 1.6. The integration time was 50x20s=1000s in the first observation and 60x20s=1200s for the rest. Our measurements yielded:

UCAC4 field stars were used for the zero point calibration. Our observations are ~7.9 weeks after ATLAS discovery (TNSAN-2024-100). The OAUNI project is supported by UNI, TWAS, IGP and ProCiencia-Concytec (Convenio 133-2020 Fondecyt).
