ARCTIC was used B half last night without issue. Russet suggested that we remove the rotation restriction for ARCTIC. The diffuser rotator repair is still to be scheduled; it was tensioned but the rotation sensor is not working properly. Agile is still at the repair shop. ARCES is back and usable after the issue with daytime metrology data described in the site report above. Russet will check with Amanda about headers not being written properly for KOSMOS; this anomaly affected Zach BT a few weeks ago.

-  * Nancy: get ROM costs for new KOSMOS grisms. Sarah reported that she has a finalized quote from one vendor. The grism design turns out to be a little complicated, but also, costs have gone up, so these are more expensive than we expected (ballpark $20k apiece). Therefore, we need to explore potential funding sources. We have reached an impasse in terms of prioritizing the desired grism; Nancy will amass all previous emails with grism requests and send to UC reps to query users about whether there is broad interest in a particular grism. This could help identify funding sources, either individually or collaboratively. STATUS: OPEN.+  * Nancy: get ROM costs for new KOSMOS grisms.

Cuba Foundation for several grisms and hopes to have it submitted before the next Users Committee meeting.
   * Nancy: Ensure that a short description of the impact of satellites be posted on the APO website somewhere and updated every 6 months or so. Nancy received examples of this issue from Anne Verbiscer and will get something added to the current (and new) web site.

 Open action items from this meeting:  Open action items from this meeting: 
  
-  * UC reps: poll your Agile users concerning whether or not they adjust the camera gain setting - there are 3 selectable gains - software electability is what has changed and can't get it to work. From last feedback with repair facility that can still be adjusted manually. That IS working. If they are unable to make further progress on software changes we will get camera back and gain can be sleeted at beginning of run by observing specialist. Will likely have to remeasure those gains because the main readout board was changed out during previous camera repair. Previous choices were ~ 1, 2, 4 e/DN. +  * None.

-  * UC reps: alert your users to the fact that plans are being formulated for decommissioning DIS (see below).+
