              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
High humidity the entire night. But we prevailed!  DD04 was able to get some exposures, GS04 made all of their time, but things got a little foggy during switch over and we stayed closed for about an hour until it cleared.  It was then humid skies with good seeing for the rest of the night!
The dome weather sensors went down around 2:55 am and the enclosure window failed once at 06:34:28.  There was no sound to the left dome door tonight.
