TL;DR
This study reports seeing measurements at OAUNI in 2016 and 2017, showing median values around 1.8 arcsec, indicating reasonable sky quality suitable for astronomical observations.
Contribution
First detailed seeing measurements at OAUNI site during 2016 and 2017 campaigns using broadband filters, providing baseline sky quality data.
Findings
Median seeing of 1.8 arcsec in 2016
Worst seeing of 2.0 arcsec in 2017 due to climatic phenomena
Best monthly seeing conditions around 1.5 arcsec
Abstract
We present seeing measurements at OAUNI site gathered on 2016 and 2017 campaigns using V and R broadband filters. In order to quantify the seeing we used the full-width-at-half-maximum from stellar profiles on photometric sequences during the observational windows of our supernovae program. A typical median seeing of 1.8 arcsec was found on 2016 and a worst value of 2.0 arcsec on 2017. The last one was probably affected by anomalous conditions related to the 2017 extreme climatic phenomena. The monthly first quartile analysis indicates that best seeing conditions can be achieved at a level of 1.5 arcsec. In general, our results indicate a reasonable sky quality for the OAUNI site.
