Problem(s) Encountered:

 ...dome glitched and started moving around on its own around 3AM so had to switch to manual mode (it also did this yesterday). Also, the guide probe y-axis limit switch has failed but I was able to find guide stars by just moving in x. 

Solution:

Dome issues sauch as this occur from time to time for unknown reasons.  Manually controlling the dome by matching dome and telescope AZ is a suitable workaround.  Sometimes also simply homing the dome can resolve teh issue.

For the guide probe, the home limit switch for the y-axis failed.  Switch replaced.
