Opened at 21:20. Telecope failed to slew from UW08's Remark initially, but worked after a slew from APO's Remark interface. Clouds returned and telescope was closed again at 23:00. The DIMM was not started because of the virtually continuous cloud cover. 2nd Half Observing Specialist: McMillan Second half was mostly cloudy, and the telescope was closed until 04:00, when the clouds thinned slightly. Only a few useful images were obtained, and among those no image motion was detected. An LVDT monitor was running in the control room, and the only variations appeared at the very beginnings of slews.
