              ------------- ACTIVITY LOG --------------
Observing Specialist: D.DeColibus
Some light clouds persisted on the western horizon for the first half of the night, which wasn't great for our observer attempting to observe setting targets.
We lost a few minutes in the switchover due to difficulty moving DIS and a misunderstanding regarding guider focus offsets.
Second half observers reported a change in instrument header cards, which apparently affects all instruments.  Reported as a PR.
No other problems tonight.
