              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
We had several waves of rain, hail and wind before sunset, and then lots of waiting for clouds to pass.  There was one brief thin patch and we opened barely long enough to focus and find out how bad the seeing was, before the humidity spiked higher than I was willing to push it.  I didn't count this as usable time.
In the morning, there were just a few snowflake to see us on our way.  This is the earliest first snowfall in a while, but maybe it doesn't count since it wasn't enough to stick on the ground.
