              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started mostly clear with high thin clouds.  We tested a method to circumvent the Tspec guider, then handed the scope to John's program. It cleared for a while, and we had ok seeing.  Around midnight, high thin clouds came back. They thickened around 04:00. It cleared again around 05:00.  All programs got their full times.
