              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Well, color me surprised!  I was expecting us to be completely rained out for nearly the whole night and then to be cloudy the rest.  I guess Russet made a deal with the dev...dew point.  The clouds started clearing right at sunset and the dew point didn't sky rocket so we were able to open on time.  Apparently, this is the best laser data in a long time.  Seeing was good/excellent with subarcsec achieved during B half.
Theme of the night "You can't take the sky from me."
