                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 Nearby radar returns the first half of the night and then orographic
 clouds the second half of the night. The observer gave up at 03:30
 since they could not get any usuable science with the time left and
 the skies still were overcast at that time. Within 15 minutes
 however the skies started to clear. I opened and attempted to do
 some engineering with fastcam. Aligning the camera proved to be
 a very difficult one person task. I made no real progress other
 than learning there is still a major problem with the mechanical
 design of the mounting fixture. The camera still can not be focused.
 I will discuss it further with Nick today.
