Problems: 

When starting dome flats in the afternoon, we discovered condensation on the dewar window.  We found the dry air hose disconnected in the Cass cage.  We reconnected the hose and after some time the condensation was gone. 

After finishing SV observations for Kilpatrick, we moved to another field and performed a focus sequence.  At the end of the focus sequence, we couldn't change the focus again.  There was a problem withthe SMC.  After SMC was restarted we were able to focus.

In observing scripts, there is an option to select set the OBSTYPE keyword.  The grid sequence GUI shows the OBSTYPE selected, but it doesn't write it to the header.  It also seems that I cannot change the obstype by hand using the obstype menu.
