              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
We needed to close at 21:30 due to dust levels outside getting too high.
Dust dropped below 4K for 15 mins so I was able to open for APOLLO.
We closed due to humidity at 02:50.  Humidity stayed well above the clousure for the remainder of the night.  I gave up at 05:40 after consulting with the observer.
