                ------------- ACTIVITY LOG --------------
Observing Specialists: G.Saurage
High winds and high dust all first half. Conditions began improving after
11pm. During Apollo time, in-dome tests discovered technical problems.
They were not able get on-sky because of technical issues but dust levels
were still near closure limits during their time. By 1am weather
conditions had been safe for long enough to open, although dust levels
remained high all night.
