Problems:
1) During afternoon calibrations, IB were not building the images properly and some CCD extensions were missing. A SISPI restart solved the problem and calibrations were manually restarted where it was left
2) At the begining of the night (moving to the second standard field) the telescope brakes got activated. Problem was solved after re-balancing th etelescope. Total time lost = 1 hour
3) Louver windows closed at 8:40pm due to alarm of high humidity.
Also, during afternoon calibrations there was a "DECAL not ready" alarm. Solved by reseting the DECAL computer
