              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
I got a motion error on the azimuth on the first test slew.  It moved about 4 degrees before it stopped.  I did an axis stop/init and then it slewed fine.
The DIS slit masks were stuck on the 5.0 arc sec mask, regardless of the slit in place.  I did a dcam init to fix.
Some clouds to start the night but things cleared around 23:00.
My 2nd half observer lost her internet connection and had to re-connect.  This caused her slit viewer images to stop updating.  She had to re-start TUI to fix the problem.
