              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
First half we had clouds and a few sprinkles.  In the middle of the night we were able to open for a little while and work through varying clouds until the humidity got too high.  Then humid became foggy became rainy and we couldn't re-open.
Tspec images were corrupted at the start of the night.  I left it off for a while, and when I turned it back on in the morning, it was... still corrupted.
