              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend,D.DeColibus
We did not open at the start of the night due to clouds and radar returns.
At 01:11 we turned on press fans and turned of TelEx and InTex fans & closed louvers due to pollen/relatively high dust counts (verified with handheld dust counter). We kept an eye on the dust counts, and it seems the high count was a spike and not a prolonged high dust count.
Back to normal dust counts at 01:56, switched the fans & louvers back to regular configuration.
Around 03:00 the skies cleared up and we had photometric conditions.
No motion errors again tonight!
