              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend&R.McMillan
We had some thin clouds on and off all night, most of them were dissipating just as they reached the mountains. Though wind gusts were close to the limit in the afternoon, they dropped far enough down before sunset and improved over the course of the night.
Dataq was frozen again when I arrived, with "Please wait for device reconnect" message. PMSS listed as "Off Line" in the tcp/ip manager. Restarted at 5:10 am.
No other problems.
