              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night started out with a wonderful eyepiece tour for the Board of Governors!
Nice clear skies with good seeing, probably about 1 arc second. Everyone got cold and tired
around 9:45 and we called it quits with the remainder of the time being donated to
JH02.
The NA02 class did GREAT! They were teaching each other not an hour into the class
and everyone was getting the hang of observing. Unfortunately, dust particles spiked
around 4:30am and we had to close. They stayed elevated and there was no hope of
opening again before twilight.
No problems tonight.
