              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started with some check-out excitement.  The scope's altitude axis got lost.  After consulting with Russet and Fritz, we reset the scope to a known altitude and carried on.  No sky time was lost.
CU03 let the previous program run a little longer.  The skies varied as clouds moved in, from mostly clear to partly cloudy.  Clouds and haze thickened after 02:00. They thinned again and CU03 was able to get their data.  They logged off early, and AP01 started setting up early.  All programs ran, no one was shut out.
