19:45 Ready to open. Cart 2 plt 634 up the telescope. The mostly clear sky, but
humidity gorwed rapidly up to 84% at the sunset. 
20:50 telescope open, clear sky. we go to field and didn't find stars -probably
the rotator's amplifier hasn't been reset. We axis init twice and found a fk5
star. 

We also found the rotator error:
