                ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st & 2nd shift: Eddie Bergeron
 Got started at 19:05 with focus. Just finished focusing then had to close due
 to high humidity. An hour later it had dropped below the limit and the sky
 was clear until 23:00, when clouds started moving in. Don was able to continue
 getting enough signal through the clouds until 01:45 when it became to thick
 to bother. Humidity was hovering just below the closure limit at that point
 anyways, and stayed there the rest of the night. Had an MC crash at 23:30. A
 restart took care of it and we continued. Spent the rest of the evening
 taking 30-min quartz specflats with the echelle and a few more Th-Ars.
