Problems: 

4map (?) went down at start, which didn't allow for guider to work. Restarted and everything was fine for a while. At 1:30 UT SISPI didn't stop an exposure while the dome was in the way, had to point to zenith to restart everything. Lost about 15 min. Later while pointing close to horizon (about 28 deg elevation) the SISPI failed again. Lost about 20 min to require. 

 

Otherwise, clouds caused some guider loss.
