              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
We struggled with clouds off and on during the night, but seeing was quite good and we were able to stay open most of the night until humidity rose near morning twilight.  The observer was able to get some useful-looking spectra with DIS despite its problems.
