Observing Summary:

Another good night.
2 short remarks :

a. Prospero got stuck once during the countdown in an exposure,
   that exposure was dutifully completed and recorded, but afterwards
   Prospero could not be made to do anything at all anymore.
   A simple shutdown of the command window, and a restart combined 
   with  ossetup  solved the problem (as suggested by someone else in
   the searchable problem&solution database).

b. once in the dome, while rotating the instrument with the hand paddle,
   we heard quite strange noises coming evidently from underneath the
   floor at the SE ( the DANGER zone to be entered only by permit).
   Reminiscent of some possibly sizeable animal gnawing or using
   its claws. Those scratching noises persisted for at least 15 minutes,
   but after they had stopped : total silence, no repeat.
