Also Present: 
Linda French, Robert Stephens, Kyle Connour
Problems: 

Dome and primary mirror environmental control failed this afternoon. Consequently, the primary mirror was warmer than the ambient temperature all night, and had a noticable effect upon the DIQ.

Shuuter failure 00:12 local -- 15-minutes lost. 

TCS kernel failure at 05:43 -- 9-minutes lost for TCS reboot.

SISPI fell-over at 07:02 local ... components TCS and HEXAPOD not ready. Strange (linked to internet failures, who knows ?). Re-started TCS, Hexapod and GCS toles in the Architect Console, which along with a resetting of the observers/propID fields, and a re-configure, worked well.  Seven (7) minutes lost.

 

No cold water is running in the ladies bathroom on the G-floor in the Blanco building. The only water with which to wash one's hands is scolding hot. Please turn down the water temperature or supply a cold water tap too.
