Today clouds were playing Tetris above our observatory: clear skies to the west with about 20% cumuli and a gentle western wind packing them together above the observatory. Despite that a few minor gaps allowed observation. Transparency was excellent, but with the scintillation monitor reporting mediocre seeing. I made the following observation:
