              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Clouds, wind and dust tonight.  Light snow started falling around 03:15.
By 04:15 we had about 1/4 inch on the ground, basically enough to cover the ground in white, and still coming down with more on the way from the satellite image.
SPIcam heater turned back on.
I called it a night at 04:30 with high humidity and snow coming down.
