              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started clear, with somewhat strong winds and poor seeing. Winds kept getting stronger. By 19:40 pointing limits were needed. Around 23:00 winds were gusting over what we could take even pointing away from the wind, so we had to close. We were able to open again for DD02 program at midnight. Gcam needed a hub startNubs at this time. Winds completely died down, seeing was fair and we stayed open the rest of the night.
