              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started with scattered light rain, giving way to just cloudy conditions. Arctic filter wheel was tested during checkout, it behaved itself. The clouds remained thick until 23:00 but even then, only the moon was visible (no stars).  Weather images showed the clouds clearing out soon, so we attempted an opening around 02:27.  Had some trouble with the eyelid, which was resolved (for now) and we commenced observing at 02:45.  We stayed open until just before dawn.
