              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Ecam needed a power cycle during checkout tonight. Evening started mostly clear and getting clearer. Gcam also needed a reset as it had lost the piston position. Had about an hour of 80% clouds that ended the pointing model early (around 23:00). It cleared up again shortly after, though the seeing was bad.
