              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
A very orange moon tonight, peeking through the clouds,from the smoke in the atmosphere.  Clouds abscured the stars.  We also had a lot of pollen falling.  I set the pollen plate out around 10:45 to start the counting.
Definate smell of smoke after midnight, both outside and in the ops building.
Sky was starting to improve, still cloudy for half the sky.  Flashlight showed lots of particulates flying in the air.  Smell of smoke so it may be a combination of ash and pollen.
SDSS reported around 04:00 that larger chunks of ash were now falling like snow outside.  We gave up at this point.
We never opened tonight.
