              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
I thought the weather was going to be ok...I was wrong.  Things were not terrible (even bright!) at 4pm.  However, 30min before sunset the clouds formed on top of us and we were not able to open. They cleared just long enough to tease UW06 and they grabbed a few exposures, but not much.  There was light rain about 2 am but everything blew out after 5 am.  CU05 was able to grab a solid 45 min of data and the seeing was even really good!
No problems tonight.
