                ------------- ACTIVITY LOG --------------
 Observing Specialist: W.Ketzeback
 High winds and dust kept us closed until 01:40. The rest of the night went
 smoothly even though dust levels stayed borderline all night and the
 pressurization fans needed to be run all night and louvers closed.
