            ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan,C.Gray
The weather was clear most of the night but the seeing was unknown as we defocused the guider images.
The first half of the night was spend taking a large pointing model which was gorgeous but,
enevitably, futile in its use.  The guider instrument block had changed and needed to be updated.
We lacked the software to conduct a proper instrument block so we did the instrument block by a
quick and dirty hand method. We then repeated the pointing model during the second half of the
night.  This served as excellent training for the Gray minion as this was her first time
conducting a pointing model and, really, it's best to do it twice.
