              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
A beautiful clear night tonight (considering the forecast was cloudy earlier in the week).  Russet took throughput measurements with ARCTIC while I started working on getting finder charts and adding to the wiki page set up for the measurements with ARCTIC.
The second half of the night went smooth with some clouds coming in the later portion of the night.
Ed notified me of a UPS failure on the intermediate level in the morning.  He will look at it when he comes in.
No problems otherwise.
