Summary
------------------------------------------------------------------------

The predicted humidity never came tonight. Instead we were treated to fabulous seeing that stayed below 0.7" for most of the night! We used the great seeing and moonless sky to complete some high priority dark time observations, including some DDT blocks. Unfortunately, our perfect night was cut short by payload issues that were not recoverable.
