              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend&C.Gray
The CU class got weathered out for a second night in a row :( Though the snow we got last night and today had melted by sunset, it started snowing again around 18:30. I ran the snow program from about 20:00 to 04:30. Once the snow stopped we had freezing fog the rest of the night.
There is snow on the dome so I parked south, hopefully it will melt again tomorrow.
