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

* Took more StarCam data to investigate polar misalignment. A new
plot is posted on the blog that shows the results from last night.

* Ran six tracks as though we were undertaking normal
observing. Three tracks ended abnormally, all with fatal following
errors.

* Hitesh ran SAMS tests. Conditions were beautiful, so hopefully he
got alot of good data!
