Multiband photometry of Type II SN 2023gfo (TNSTR-2023-858, TNSCR-2023-871) on 2023-05-24 (UT) was gathered with the OAUNI 51cm telescope (arXiv:1512.03104) at Huancayo Observatory, Peru. CCD imaging using VRI filters was performed under non-photometric conditions (seeing ~1.8") and airmass lower than 1.6. Total integration times of (45x20s=900s) for V, R and I filters yielded:
| Date (UT) |
filter |
mag |
| 2023-05-24.228 |
V |
15.60 +/- 0.01 |
| 2023-05-24.197 |
R |
15.33 +/- 0.03 |
| 2023-05-24.212 |
I |
15.12 +/- 0.05 |
UCAC4 field stars were used for the zero point calibration. Caution must be taken in SN 2023gfo magnitudes for possible contamination with the host galaxy. The OAUNI project is supported by UNI, TWAS, IGP and ProCiencia-Concytec (Convenio 133-2020 Fondecyt).
