Observing Summary:

Clouds started at 2:00am and we closed dome at 2:45 right on time
to cover the telescope from the light rain. It stopped sprinkling
at 2:50 and we continued observations at 3:05 am.

The humidity on the Vantage PRO 2 device was still 20% all
the time so we decided not to fully rely on it in the future.

We also noticed large leakage in the Liquid Nitrogen rubber hose.
