              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
We may have had some issue with a ARCTIC filter holder being too thick and then mis-aligning.  Details sent to engineering staff.
We fought clouds most of the night.  Finally around 23:10 the observers object was getting swamped by clouds and setting so I called the last hour loss to weather for them.  I switched to the echelle during that time and was able to focus on a bright standard with NO filter,  that's how bad the clouds were getting.  Seeing was horrible too at 3.0+ arc sec with the Echelle.
I let the NM04 observer use the cloudy time since they were observing a really bright target.
No other problems tonight.
