Pereyra, Antonio2025-08-272025-08-272025-08-19http://hdl.handle.net/20.500.12816/5737We report photometric observations of Type Ia supernovae SN 2025plf and SN 2025rbs, obtained with the OAUNI 51cm telescope at Huancayo Observatory, Peru. CCD imaging was carried out in R filter on 2025-07-25 (UT) under non-photometric conditions, with airmasses lower than 1.5. The integration times were 60x20s=1200s for SN 2025plf and 45x20s=900s for SN 2025rbs. Our measurements yielded: SN | Date (UT) | filter | seeing (") | mag, 2025plf | 2025-07-25.261 | R | 1.9 | 15.61 +/- 0.11, 2025rbs | 2025-07-25.281 | R | 2.0 | 12.19 +/- 0.01. Zero-point calibration in both cases was performed using UCAC4 field stars. The observations were gathered ~25 days after the discovery of SN 2025plf and ~11 days after that of SN 2025rbs.
