              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
There were more clouds than the forecast said, but the scheduled science program and also a special pickup science program were able to get some useful data.  I also took time in between to do the highest-priority engineering task, but I wasn't able to get any others done.  After a while taking images and spectra of clouds, I decided it was time to close up.  Once the sleet got close to the site I decided it was time to go home.
