                ------------- ACTIVITY LOG --------------
1st half Observing Specialist: G.Saurage
Overcast and high humidity at sunset. Continued high humidity and some
snow rest of first half. I worked on DIS documentation and took some
additional DIS wavecals and flats at different wave centers.
2nd half Observing Specialist: R.McMillan
Snow and graupel and fog.  I ran the snow program and did some more
tests of the potential new flat field paint.
