              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
We had an issue with the ARCTIC diffuser not wanting to move into place.  Took about 15 mins to fiddle around and eventually go up and remove the instrument to see what the issue was.  PR submitted.  Slid the diffuser in place by hand initially and then cycled a few times to see the issue.  I left the diffuser in for the observer and advised of the issue.
