Observing Summary:

My first night back at MDM after a year and a half.  For the most part a great night. 
Several issues.  First, the big door is very sluggish.  It takes alot of effort to open and 
close it compared to what I remember.  You need gloves so the chain does not chew up 
your hands.  Second, the TCS crashed around 3 am.  The symptom was that targets
were not appearing when sent to Next Object.  After restarting JSkyCalc and Bridge first
to no avail the problem had to be a hung TCS.  I restarted it using the instructions and it
came up fine.  Finally, the guider would not guide afterwards.  By this time it as the end of
the night so I will reset the guider before observing tomorrow night.
