Problems: 

In the beginning of the night, we had to reboot the observation system after 'abort' an exposure. 

During the night, observer console was stuck twice and after one of the accidents I could not see some images

from the list of Exposure History in the observer console. 

Comments: 

It was impressive that read-out time was very short and the whole system worked very smoothly during the whole night.
