              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
A good night. Clear and clear and more clear. Seeing started good, and got better and better. Some of the best seeing I've witnessed. High thin clouds began to plague us around 01:30. Clouds came and went, thick at times. It started to clear again around 05:45. We were open all night.
