              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend,C.Gray
We had some clouds that cleared up right after sunset. The dust counts were elevated in the early evening but went back down.
We haven’t lost any students yet.
We were able to move the tertiary to NA1 by homing twice and then commanding it to move from talk2boxes. Tert rot currently reads "?" in Enclosure window but it's at NA1 and clamped.

Louvers and intermediate level door are open and IntEx fans are on for cooling.
