-xxx+We had the first snowfall of the year at APO last week. DIS servicing has been completed; the scattered light is still with us. We had an issue with the telescope this morning: a tripped breaker caused a motion error, which has since been remedied. We introduced Gordon MacDonald, who was recently hired onto the APO staff as a  software person for the 3.5m. Welcome Gordon! His areas of responsibility include working on the migration of the newest version of TUI (in python3) to various platforms, updating the control software for different instruments, and helping with an upgrade of the hub and its associated software. [The hub is the communications server that acts as a "traffic cop" between instrument controls, telescope controls and the user.] Caleb Wang joined the meeting from APO; he was there to get an introduction and overview of the facility and instruments.

-After nearly a year of KOSMOS usage on the 3.5m we are now planning to remove it from shared risk category. Going forward it will be offered to our users as a standard facility instrument. We do still have a punchlist of issues that we're working on, but after having met to discuss those items it was decided that nothing on the list impeded us from moving it off of shared riskWe are aware that the bias level appears to be changingand the associated controller issues are still being worked on. There are also still some deliverables we are waiting fori.e. the new slits. Over the next several months we will be reaching out to KOSMOS users who have exercised the instrument for different types of targets (extended source, faint limit, etc.) to help us understand the ramifications of some of the known instrument issues on their data.+The manufacturing of the second round of slits is underwayThere have been some delays in the WNF (UW facility where the slits are machined) and we keep getting postponed off of the equipmentThe first ones ready for production are waiting to be aluminizedOnce we sign off on that set, we will do a big batch. We hope to have them done by the end of the CYIf people have requests for slits of unusual sizes they should let Sarah know so we can get them in the queue.
  
-Our meeting about the status of KOSMOS highlighted the fact that APO does not have a standing definition of shared risk and how to transition an instrument off of that status, so as an output of the conversation over the next month we will be putting together a document that defines shared risk and the expected path that takes an instrument through commissioning to becoming a facility instrument.+We are converging on process for the generation of MOS slit masks for KOSMOS with Bill's help. Joe Burchett (NMSU) has been working on it but we would like to develop a workflow for making them more easily. We have settled on vendor in Arizona that has manufactured slits for KPNO; they are most affordable and have the fastest turnaround. If we could identify one or two more people who are interested in the MOS capability that would help us work through the processJoanne has indicated interest so she will be next - is there anyone else?
  
-Note added in proof regarding the issue of the wavelength coverage of the blue center slitCurrently the blue grating on KOSMOS in the central position covers 3800-6600 A, so the red cutoff is very close to Halpha. This setup is not ideal for observing magnetic targets, which have Zeeman splitting of the Halpha line. The high slit position shifts the wavelength coverage to 4150-7050, which is good for Halpha, but now misses some of the higher order Balmer lines. So the question was asked whether it would be possible to have another slit position that would cover the range from 4000-6800 A, or something like that. **UC reps: please query your users to determine if there are additional needs for this capability.**+Last month we discussed the issue of the wavelength coverage of the blue center slitCurrently the blue grating on KOSMOS in the central position covers 3800-6600 A, so the red cutoff is very close to Halpha. This setup is not ideal for observing magnetic targets, which have Zeeman splitting of the Halpha line.

Both Eric B. (UW) and Adam (CU) responded that they have several users who would need this capability.

Interested users are reminded to look for OPEN and DD01 blocks listed in the Q4 schedule and request it if desired, especially if they can make use of small blocks of time, especially with ARCES or Agile (for which no instrument change would be required).

Interested users should contact Ben, Russet, Nancy, Amanda and Bill to determine whether there is an option for getting trained. We are not yet ready to offer the Shelyak as a general use instrument on ARCSAT due to software issues that make its operation challenging, but we are open to testing the system with a few users who might be interested in helping us refine its operation.

-The January 2023 AAS meeting will be 8-12 January in Seattle. There will be lots of UW users there, and hopefully many from other ARC institutions and lease partners as well. The abstract deadline for the meeting is Tuesday October 11! We discussed options for doing something special for APO or ARC usersLast month the UC reps were asked to poll their users to see if they would be interested in an APO event (e.g. a meal or reception one evening) during the AAS meeting. The response was moderately enthusiastic, so Nancy will continue to explore optionsWe will definitely have an APO booth in the exhibit area, so in month or two Nancy will be looking for volunteers to help us staff the booth. Stay tuned!+The January 2023 AAS meeting will be 8-12 January in Seattle. It would be good to have a mix of APO staff and users at the booth through the meeting. Nancy will order stickers to give to people for their badges to indicate that they are presenting results from APO observationsAlso, we will make digital image "sticker" available for download so users can add it to their iPoster if they made use of APO dataNancy will also create spreadsheet where people can indicate when their talk or poster is, as well as their availability to help out at the booth.  Note added in proof: the spreadsheet is here: [[https://docs.google.com/spreadsheets/d/1F_oM3sqCz51Ynb1HvPftlr9RB5zvBFUjJN5yOq5Bu1s/edit?usp=sharing]] .
  
 +We will discuss this further at our December UC meeting.

   * Nancy: start investigations re: short wavelength throughput (climate data, other facilities). Status: OPEN. No news. Old news: Nancy reached out to some colleagues at other observatories to ask about short wavelength performance degradation of their optical coatings. She got some names from Bill and will contact those individuals next. The ongoing discussions about new coatings for the primary also relate to this issue so we will determine our coatings first before continuing to pursue this line of investigation.   * Nancy: start investigations re: short wavelength throughput (climate data, other facilities).
