              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
I had to reset the mirror covers to open them, and then only the first set of petals closed when I closed them for cals, but cycling them from the enclosure window fixed that.
We had high wind speeds and dust counts during the day but everything calmed down in time for us to open--but we did have to observe through obstructive clouds for a large part of the night.
