                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 Another night with variable clouds and seeing.  We closed for a
 while when the clouds were too thick to work through.  Wind and dust
 skimmed close to the limit but came down again.
 APOLLO had to give up time again due to a failure of the same power
 supply that had been worked on since Tuesday.  More work for
 tomorrow!
