              ------------- ACTIVITY LOG --------------
Observing Specialist: D.DeColibus
Night started with borderline dust and high winds, but we opened around 18:30.  Dust dropped relatively quickly afterwards. Weather stayed clear with moderate winds the rest of the night. Some light clouds started creeping in the southern sky around 06:00.
Shutter on Echelle stuck open, was unable to get the morning IOL measurements. Did not interfere with on-sky observations. No other problems.
