              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Weather was borderline for first half, so I let the onsite observer do training and pickup science for a while.  Once conditions improved, I got some measurements of DIS vs slitviewer focus, collimation with the Shack-Hartmann, a pointing model, and ARCTIC throughput measurements.
