              ------------- ACTIVITY LOG --------------
Observing Specialist: D.DeColibus
After work done on the echelle slitviewer during the day, we had to make a new mask and change the imcenter. Instructions in the wiki have been slightly modified for the new ecamera.
Night started with partly cloudy conditions and a lot of cirrus. While the clouds did thin out, the cirrus persisted for the rest of the night.
Aside from having to reboot ARCSAT around 3 AM to solve an issue with the focus script getting stuck, the night was otherwise uneventful.
