We report photometry of Type II SN 2023ixf (TNSTR-2023-1158, TNSCR-2023-1164) gathered with the OAUNI 51cm telescope (arXiv:1512.03104) at Huancayo Observatory, Peru. CCD imaging in R filter was performed on two epochs under stable conditions (seeing ~1.7") and airmass lower than 2.5 (target with low altitude). Our integration times were 54x20s=1080s and 50x20s=1000s on 2023-06-20 and 2023-06-21, respectively. Our measurements yielded:

UCAC4 field stars were used for the zero point calibration. Our observations are ~32-33 days after the earliest detection (AstroNote 2023-130). The OAUNI project is supported by UNI, TWAS, IGP and ProCiencia-Concytec (Convenio 133-2020 Fondecyt).
