                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 First half of EN01 time was used for drive tuning. Improvements were made
 to the parameters especially in the parts of the sky to the North-East and
 North-West were the azimuth directions reverse. Small compromises had to be
 made when these new values were tested on the high altitude meridian
 crossings however. In the end we believe we did make improvements but
 were not able to find parameter values perfect for every part of the sky.
 Thanks to Russet for coming in first half to help with drive tuning. Seeing
 was too poor to test the trouble areas with spicam blind tracking tests.
 Likewise, as we were about to adust the focus position of Fastcam the winds
 became too strong to open. We were closed the rest of the night due to high
 winds and dust counts.
