              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
During test slews, I got a stop button error on all 3 axis.  Rotator was working before properly, and it had just started to move the telescope in Alt/Az when the stop button error occurred.  Looks like a dome collision.  I cleared it and also reset the big switch on the intermediate level (it didn't seem one light came back after I moved the telescope).  Next slew same issue.
I then reset the drive controller for the az axis. This cleared the issue.
We were delayed at the start of the night by local thunderstorms (they made lots of noise but no rain, but they looked pretty dark and threatening).  We finally were able to open around 21:50.  The clouds came back around 22:50 and basically stopped observations, although we stayed open until we needed to close at 23:20 when there again was the threat of precipitation.  We never re-opened and finally gave up at 04:20 due to clouds.
