Problems: 

Lost an hour at the beginning of the night owing to problems slewing, traced to faulty oil pump. The problem recurred at the end of the night, losing a half hour.

Also had a 2 hour computer failure in the early morning hours. DECam reported missing CCD extensions for 834458. We tried to restart syspi, but it did not come up correctly. Hernan had to come back up and use a master console to clear processes. Nothing especially exciting was happening when the failure occurred.

Comments: 

Good weather, some lost time owing to equipment issues.
