Yebes Observatory belongs to the Spanish Light Pollution Network and takes part in two projects: SQM Network and NixNox. We measure the sky brightness during the night with a SQM-LE photometer. The sky brightness is depicted below as a function of time. The interval at which the Moon is above the horizon is shown with a pink background. The sunset and sunrise are marked as dashed vertical lines. Below the sky brightness from yesterday night.
