              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started clear, but some high thin clouds rolled in around 19:00. Seeing was good. It cleared out by 21:00.  After 01:00 the winds picked up and seeing degraded. Minor incident with DIS gratings mis-aligning, most likely due to setting the centers with DIS inverted.  Other than that, it was a quiet night and we were open all night.
