Problems: 

We had a fault with SISPI due to a comfort display failure at 07:18 UT. After restarting SISPI, it was tested Ok. (0.5 hours lost)

Comments: 

First half of the night was observed under good skies conditions, average seeing ~1.3" and clear sky. During the second half, the conditions get deteriorated and we got a fault with SISPI which costed us half an hour to recover it. I charged 0.25 hours to weather as we lose guiding a couple of times because of the poor seeing. Apart from that Kathy Vivas and Claudio Aguilera helped me to troubleshooting the fault reported. Thanks a lot.
