Also Present:

Problems: 

0.5 hours lost for focus. When running the nf_focus_wide, the coadds of the exposure is changed automatically to 12, even if we set it to be 1 before running the nf_focus_wide. It is solved by restarting the software. (2:50-3:30, by Tianyu Tu)

The weather is becoming cloudy in the fourth quarter of the night (by Tianyu Tu).
