Today started out grey, but the sky more or less cleared to about 50% cumuli, topped with large patches of stratus. Transparency was mediocre to poor and varied a lot (there was never a totally clear moment), and the scintillation monitor reported varying seeing, going from excellent to extremely poor. I made the following observation:
