              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
Dataq frozen again (though only once tonight), power cycled and updated PR2144.
We had a few very thin clouds and mediocre seeing as the night progressed, but mostly good weather and were open all night.
Please beware of the DSSI cart and cords on the NA2 side of the dome.
