Serious problems with the slicer's motor tonight. During the calibrations taken in the afternoon, several error message were given by the software about the slicer position. Starting the night, I kept receiving these message, so I decided to restart the software, the Chiron' PC and the torrent trying to solve the problem, it was not possible. With the help of David Rojas, Manuel Hernandez, Rodrigo Hernandez, Marco Bonati (by phone) and Javier Rojas (by phone), we tried to solve the problem in different ways, it was not possible. Even more, the focus started to give (extra) problems, it was not possible to give the 

''home'' instruction, as in the slicer's motor.

Because of the complexity of the problem, we lost the observation night. Marco Bonati will arrive tomorrow to the observatory to work on this problem, he is also trying to contact with Andrei Tokovinin to have his expert point of view.

As a consolation, we lost a very bad seeing night (over 3.0 the most of the night) with a 95% of moon luminosity.
