              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Clouds kept us closed for the first part of the night.  Around 22:10 humidity was nearing limits and by 22:35 we were over the humidity limits to open along with a large cloud bank on radar to our east.
When I handed KOSMOS over to the 2nd half observer to do cals, TUI reported the cal stage needed to be homed.  A calstage home fixed the issue.
Humidity, clouds, and fog were what we dealt with for the 2nd half of the night.  We never opened and called it at 05:00.
