Summary

The weather made observing very difficult for us tonight. Dark clouds forced us to close during the first half of the night. After reopening, the seeing conditions were very poor, which limited us mostly to lower-priority observing blocks. Later, the humidity increased again and forced us to close for the remainder of the night.
