Problem Reports
PR Number	Times	Time Lost	Description	Response
4668	23:01-23:02	00:01	Legacy server would not communicate with Structure/Dome/Shutter after all-server restart; all lights were red. Required legacy-specific restart. (OPS)
4200	23:33-23:50	00:17	Failed to acquire trajectory errors that persisted until TCS restart (OPS)
4862	23:00-23:00	00:00	Noticed that the guide cameras were taking images very slowly, and restarting pas server did not fix it. (OPS)	Called Randy to help investigate, and he found that pas was taking a long time getting information from legacy due to the log file problem. He deleted the log files and the cameras worked like normal; also structure/dome motion was once again possible.

Ops Comments	none

TO Comments	High wind and high dust counts kept us closed for majority of the night. Left dome and structure pointed into the wind at the end of the night.

RA Comments	Heavy dust storm and high winds at sunset prevent skyflats. Night dedicated primarily to engineering. Close by high winds and dust all night.
