              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Boresight on the Echelle slit was off about one slit width to the right of the slit.  I only adjusted it with a set imcenter command.  If it continues to be off again tomorrow, I will make a more permanent fix.
Dust (smoke) started spiking around 02:10.  Reversed press fans and closed louvers.  Dust counts were only elevated for about 15 mins (7K) then dropped back below closure levels.  We stayed open.  Another dust spike around 03:00. Went outside to see what was going on, very strong smell of smoke, came back in and dust levels were climbing and we closed.
We gave up at 04:40 as dust counts were still above closure.
Please CO2 the mirror from all the smoke we have had the past couple of nights.
