              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Dome cameras both were frozen at 00:05:12, They were froze yesterday at I think about the same time.  I am recording the time here to see if they freeze tomorrow at the same time.  Reloading the web page fixed the issue yesterday, today I got a connection timed out error.  I tried a few minutes later and it connected.
No telescope issues tonight.  The echelle used a little more LN2 from the evening fill to where I normally see it in the morning, but the IOL looked normal.  It was also warm tonight.
