Night Assistant:

Problems: 

DECal computer crashed (see the SISPI log for detailed list of alerts). Operations resumed after the machine reboot

Last moment addition: the last standard has failed (error: missing CCD extensions). Attempt to finish the standards failed. 

SISPI got stuck configuring, and was reinitizalized. We took the zeros at 06:05 local time. 

Comments: 

 Poor and unstable seeing conditions during approx. one hour of the final quarter (with seeing values ranging from 1.4 to 1.8). DIMM seeing was more stable and closer to 1 during that time (maximum being 1.3).
