              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Night started with a few high thin clouds.  Around 20:00 a large bank of thick clouds containing rain came through, so we closed for a while until it passed. We opened again at 21:13. The winds picked up and seeing was ok.  We remained open the rest of the night.
