              ------------- ACTIVITY LOG --------------
Observing Specialist: D.DeColibus
Opened before sunset for thermal equilibrium; the first program required observations during twilight, and despite an unusual Agile rotator error and apparent freewheeling, the problem seemed to resolve itself. (See Russet's PR agile/1863 for details.)
Agile observations were complete earlier than expected, so we took the opportunity to do some training with the eyepiece, and trying out some objects for the upcoming VIP visit in April, plus recording and labeling the eyepieces with the field of view and focus values.
Our NM04 observer finished a bit early, and gave ten minutes to the JH05 observer. Aside from an issue with the echelle slitviewer not updating on the observer's end, which was resolved by a TUI reboot- until it happened again, where I just took over the task of guiding because we suspected it was due to internet connection issues. Intermittent thin clouds bothered us from about 1 AM onwards.
Ran into minor issues with Apollo at the beginning with the aircraft detection system, but Russet did...something to solve it.
No other issues tonight.
