Observing Summary:

Began the night with clouds and high humidity. Shortly before 10pm the humidity dropped to acceptable levels and the clouds had mostly moved off, so we opened and observed AGN14 targets for about 2.5 hours before the humidity got above 80% again. Retired for the night shortly after 3am, with the humidity at 94% and rising.

We filed a trouble report regarding the hose connected to the LN2 tank. The very end of the hose, the part that connects to the metal tube that inserts into the dewar, seems to have a small hole in it. It sprayed (not much) LN2 when we filled the dewar. This made the filling process take longer than normal.
