Bad weather kept us closed for most of the night. A sudden drop in humidity in the early hours allowed us to open up briefly and complete 2 blocks.

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

Some good and stable seeing for most of the night allowed us to complete several high priority blocks. The humidity and seeing started to vary wildly after 1am, before humid conditions and then ridge cloud closed us just over 2 hour before twilight.

Poor seeing for most of the night restricted us to low priority blocks. When the wind swung north we got some good, stable seeing for the last few hours of the night, allowing for a handful of higher priority observations.
