              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Sutherland,R.McMillan
Despite the clouds, we were able to get some Venus data in the first half of the night. We could see banding of the atmosphere in the Tspec slitviewer which was really cool!
CU07 donated 10 minutes to CU04.
Clouds were too thick to observe through, and I closed up at 9:40pm and remained closed the rest of the night. Gave up around 5:30am.
