                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 Closed 19:55 due to blowing snow and increasing clouds.  We never
 re-opened.  I helped Don get the GFP in working order with his filters,
 slit focus, and various other little gotchas he discovered.
 Don gave up around 05:20 when it didn't look likely of any clearing in
 the clouds tonight.
