              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started with borderline high winds. Seeing was awful with winds out of the NE. No matter what was done, focus script could not get data points to converge, so focus was left at value from a few nights ago. Winds dies down but humidity spiked around 22:15, so we closed. It began to recede after midnight, so we opened again. That did not last long, as the humidity came back with a vengence, and we closed again at 01:00. Pollen was seen on windshields, so we're in to that time of year as well. Humidity turned to fog and light drizzle around 03:00. We stayed closed for the night, and gave up around 04:15.
