              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
I thought we'd be able to be on sky all night tonight... It was clear the whole night but the dust stayed at 4K, so I opened at 19:30 and then immediately closed again. Turns out the particles are probably tied to the INSANE AMOUNT OF SMOKE!!! There are huge fires in Canada and it's all being funneled down the middle of the country and reached us today.
So, we were not able to get on sky, but we ran through the Shack Hartmann test and I've started making new documentation on the new wiki. It's a slow process but, boy, it's making more sense now!
No problems tonight.
