              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
We held off on opening just a couple minutes to make sure the dust wasn't spiking.  The observer used the time to take some darks.
Smell of smoke outside when I closed the building this morning.
No problems tonight.
