                ------------- ACTIVITY LOG --------------
1st Half Observing Specialist: Frank Deglman
During the checkout, the PMSS desiccant window showed pink once again,
even though the desiccant had been replaced this afternoon.
Opened late at 21:00 due to dust.  Did some astigmatism testing of the
primary with Shack-Hartmann wavefront sensor.  Closed at 22:10 because
of high dust counts.
Recalibrated the DIMM guiding.  The default settings were 1.2
pixels/millisecond for both directions.  After running the new
calibration routine the values were around 0.5pix/ms.  The centering of
Polaris then
seemed much more accurate.
No problems noticed with the newest version of the TCC sofware 2.2.9b1.
However, we did not use it very extensively.
2nd Half Observing Specialist: Camron Hastings
I came in first half to help work with the Shack-Hartmann device and
write up the S-H section in the new 3.5-m Observer's Manual. Observing
went well except for the weather. Stayed closed second half due to
weather. I stayed around to fill GRIM at around 4am.
