Today we had regular clear skies directly overhead, but mainly stratus in direction of the Sun. In the afternoon it finally shifted for a few minutes further south, allowing to do some observations. Transparency was very poor, and the scintillation monitor reported mediocre seeing on average. I made the following observation:
