Problems: 

During dome flats, something was obscuring part of one quadrant in the images. I checked the dark slides, but they were ok. I moved the fitler to a new one (from r to z) and z was clear. Then I went back to r and it was clear as well.

========> Please take a look in filter wheel and see if something is loose. <===========

The door stuck again. I was able to get it open. That really should be fixed.

The environmental page claims the sun is down be a few degrees when it is still above the horizon!

First ARCON hang of the run at 330 am. Had to reboot ctioa4 to recover.

Thanks everyone. Three good nights.
