              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Telescope didn't like initial slew downward in alt.  I made shorter slews for the first couple then it was fine.
Humidity finally broke around 23:20 and we opened shortly thereafter.  My observer aborted their KOSMOS flat exposure, when we opened, but luckily it finished and no harm was done.
We gave up at 05:00 with high humidity and clouds.
