              ------------- ACTIVITY LOG --------------
Observing Specialist: G.Saurage
During checkout both dcam and ecam needed nubs restarted to take an exposure.
Thin cirrus at opening, elevated dust levels. Poor variable seeing. Little usable
data while open with clouds. Thunderstorm passed just to the south but close enough
to be a threat. Closed at 22:10. Clouds and humidity + dust most of the night.
