Observing Summary:

A lot of little problems and changing weather made for a frustrating night.

Slow start, was concerned about water from dome opening.  (see trouble report)  No issue but did not get on sky in time for twilight flats.  


Dome encoders failed, reset, no problems
Guider probe failed, had to quit MIS, reset computer, reinitialize

In middle of long exposure noticed guide star missing.  (See trouble report)  Eventually ended up resetting TCS
which appears to work although no idea what went wrong/ caused the error

Technical issues seemed to be solved but a few clouds rolled in limiting targets to northern sky.  Cleared up for last 3 hours of night.


Hopefully all the issues are fixed for tomorrow!
