                ------------- ACTIVITY LOG --------------
 1st half Observing Specialists: G.Saurage
 Heavy radar activity and impending clouds just off ridge kept us from
 opening at sunset. Rain and lightning at 10pm. Humidity began climbing
 after 11pm. Never opened 1st half.
 2nd half Observing Specialists: R.McMillan
 Second half started with sprinkles and high humidity and lots of
 nearby radar traces.  When the radar and humidity improved, I opened
 the cloud camera and we watched the clouds move around.  It wasn't
 until after the beginning of twilight that we had a chance of
 getting anything.  Despite poor seeing and a warm telescope, we were
 successful in getting returns from the moon.  I let APOLLO run past
 the nominal end time since the telescope was pointing west.
