              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk,R.McMillan
We performed magnesensor testing.  We performed several runs iteratively
improving the performance, we may do more iterations tomorrow.
At 22:00, switched to Shack-Hartman, but there was a problem with the LED
stage, and we were unable to see sky.
At 23:30 switched to Arctic for focus script tests.
After tests, noticed upper left quad dropped out after ICC restart
At 01:15, started altitude/focus models, but the weather turned, with
seeing becoming too poor to complete the test.
03:45 Started pointing model.  Finished at 05:00.  Numbers did not warrant
a change in models.
Aside from high thin clouds and poor seeing, weather was mostly clear.
