              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
We had rain first half.  I checked out the telescope and instruments and resolved a lot of minor issues.  There are just a few remaining that I couldn't solve, including the fact that Triplespec is in a bad state again.
Second half I was able to open for a few hours and get throughput measurements followed by some rough checks of collimation (with the telescope not quite cool).  Proper collimation adjustment will still be needed, followed by pointing models, but everything looks approximately normal for post-shutdown.
