              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
The humidity came down a little in the afternoon, but rose again before sunset, and we had clouds pressing down close overhead.  There was no chance of opening for APOLLO, but afterward humidity came down again just about to the limit and I took the chance of opening with the telescope warm.  After an hour the humidity wobbled back upward so I had to close, but at least a few spectra were obtained.  Then later we had clouds, and fog, and a little rain.
