              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started with high winds, rain and humidity. It was overcast with intermittent rain until 01:00.  The rain passed, and by 02:00 it was marginally good enough to open, so we did.  Seeing was bad, but observations got done.  By 04:00 humidity had risen too high and we closed again, and remained closed.
