 === Additional telescope and instrument discussion ===
-First snowfall last week. DIS servicing completed; scattered light still with us. Issue with telescope this morning; tripped breaker caused motion issue. Remedied. Welcome Gordon MacDonald, xxx. Migration newest version of TUI in pythini3 to various platforms. Updating software for different instruments. upgrade of the hub and associated software. (communications server that acts as traffic co between instrument controls, telescope controls and user). Caleb at APO - learning trip
+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.

 === KOSMOS update ===
-Second round of slits underway. Revising list now. Delays in WNF, keep getting postponed off equipment. First one waiting to be aluminized, once sign off on that set, do a big batch, hopefully by end of CY.
+The manufacturing of the second round of slits is underway. There have been some delays in the WNF (UW facility where the slits are machined) and we keep getting postponed off of the equipment. The first ones ready for production are waiting to be aluminized, Once we sign off on that set, we will do a big batch. We hope to have them done by the end of the CY. If people have requests for slits of unusual sizes they should let Sarah know so we can get them in the queue.
-If unusual sizes ppl are looking for we can do that.
-Organizationally mountain working on MOS slits, now is a good time to try again. Joe has been working on it but now want to do them more easily. Vendor in AZ that has manufactured slits for KPNO , most affordable and fastest turnaround. If have 1-2 ppl more interested, work through the process. Joanne next step.
-Note added in proof regarding the issue of the wavelength coverage of the blue center slit: Currently 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.** Eric Bellm and Adam - several users
+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 a 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 process. Joanne has indicated interest so she will be next - is there anyone else?

 === Q4 3.5m scheduling ===
-Nov 15B to Jeff Bary, first open time upcoming. Next up is 12/03, rest is in December, there is a lot of it, look for OPEN and DD01, esp if small slices of programs esp with echelle or agile.
+**Reminder for all scheduling requests: please send emails to Ben, Russet, Nancy, and Amanda (ajt at apo.nmsu.edu).**
+Regarding the remainder of the OPEN/DD time in Q4, Nov 15B will be assigned to Jeff Bary (NAPG). The rest of the available time is in December, and there is a lot of it. 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).

 === Q4 ARCSAT scheduling ===
-There is unassigned time available, all observations involve FlareCam, easy to slot that time
-Oct time used to train obs-spec on shelyak - ppl can request it
+There is unassigned time available with FlareCam. We used some time in October to train the obs-specs on Shelyak operations. 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.

-=== Jan. 2023 AAS Meeting ===
+=== AAS 241 Meeting ===
-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 users. Last 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 options. We will definitely have an APO booth in the exhibit area, so in a month or two Nancy will be looking for volunteers to help us staff the booth. Stay tuned!
-stickers
+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 observations. Also, we will make a digital image "sticker" available for download so users can add it to their iPoster if they made use of APO data. Nancy will also create a 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.
