              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
We fought increasing clouds during the first half.  Clouds got too thick at 22:10 and my observer stopped their Echelle observations a little early.  We observed until 22:43, when I closed so they could take dome flats.  I decided it was a little too murky to re-open for the last program after I mounted KOSMOS.
I parked the telescope due south in anticipation of snow today (and if we get any sunlight to melt it).  We threw in the towel at 04:10 with no end in clouds in site and precipitation now entering the northern part of the county.
