              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
We had thin clouds that got worse over the course of A-half but cleared up a little before B-half.
After cals, echelle got stuck with the message: failed: exposeTxt="cannot start a new echelle exposure while another is active". Restarting echelle and echelleExpose nubs brought it back.
I took a few KOSMOS camfocus measurements but the temperatures were unstable all night (and our seeing reflected that).
UW07 finished up at the start of twilight.
