              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Sutherland
Arctic checkout script did not work. Had to take biases manually. Script would say "running" and then just not take an exposure for arctic. It worked for all the other instruments though. See email.
Echelle ThAr cal failed for morning IOL script. No morning IOL as a result. See email.
Silver hose running into left side of Utah needs repair.
Opened and started venting for Shack at 17:40. Closed at 19:10 for high wind. Only focused echelle a couple times to get seeing measurements. Seeing was too variable for Shack, so no shack or pointing model tonight.
Engineering tasks done:
- Clean Kosmos Slits
- Test new echelle ICC with cals
- Wiki Updates
- Check new website for errors
Morning fills are done.
