              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Clouds thickened by 19:40 and closed us up shortly afterwards.
We opened again at 02:00 after the clouds departed and the humidity dropped below closure.
Humidity spiked at 03:45 and closed us again.
Humidity started to drop at 04:30 and the clouds then moved over top of us!
Around 05:15 the Clouds cleared (somewhat) and then humidity rose over limit again.  We called it a night at 05:45 with high humidity.
