after a rough night with force 7-8 winds and torrential rains today we had a moderate gale with gusts up to a strong gale (7-9Bft). In addition we had a layer of stratocumuli with the occasional small clearances that ran across in no time. Transparency in those clearances was very good, the scintillation monitor reported reasonable seeing in those gaps. Thanks to the shelter of our dome I made the following observation:
