                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 The evening started with high winds and elevated dust. By 8pm the
 snow flurries began. It snowed rather steadily until about 3am.
 Total accumulation at the site was between 1.5 and 3 inches. This
 morning I parked the telescope facing south for best sun exposure
 to melt any snow and ice.
 I spent the night backing up old fastcam data to DVDs to make some
 room on the fastcam icc. I also worked on some TUI scripting.
