              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening start with clouds ranging from thick to thin. Dataq had to be restared from the server end. Clouds thinned out as the night progressed. Seeing was fair. Winds were low. Starting around 20:00 the winds really picked up. They did not exceed closure conditions, however, but we had to avoid the northeast. It cleared up completely by 23:00. Winds died down somewhat as well. Winds returned after midnight, though they did not surpass safety limits. We stayed open all night.
