              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started cloudy with a thread of storms from the north.  The storm dissipated by 00:30, and did not reach us. We attempted an opening at 00:40. We were able to stay open until roughly 03:00, at which point another thunderstorm came from the north and surrounded us on all sides (but not directly over us ironically). Nonetheless, we could hear nearby thunder and stayed closed.  By 03:45 our observers gave up, not having enough remaining time nor hope of data. Ecam behaved well enough for guiding tonight, but agile needed a clock reset during checkout.
