              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started mostly cloudy with rain on the radar, but it all blew out by 19:00.  After that it was clear with very good seeing.
Ecam was showing horizontal streaks due to shutter.
Perfect night otherwise, great skies and no real problems.
