-As a status update on the MOS capability for KOSMOS, Bill got the KMS software running under certain operating systems; he can provide instructions on how to install it. He has been working with Joe Burchett at NMSU on streamlining the process; currently the software outputs file format that is used for making electronic boards but not used by many machine shops so Bill has been converting them to SolidWorks or AutoCAD. We've had a few slit masks made at the UW machine shop using a wire EDM but this is expensive. We attempted to have some made at the NMSU machine shop using a laser cutter but the results are of low quality. However, in both cases we found that the scale factor between the slits and the sky is off by a small amount, so we are iterating on that to get the slit positions to match on-sky coordinates. Bill has also been working with former KOSMOS folks at NOIRLab to work out the intricacies of setting up the software configuration files to make it more applicable for APO. We are hoping by mid-September to have the process streamlined to help users create slit masks for multiobject spectroscopy. UC reps should remind their users of this exciting new capability at APO!

 === Summer shutdown ===
+Last month we discussed the fact that we have to delay the realuminization of the primary mirror due to the Contreras Fire at Kitt Peak. We are still actively pursuing other options, including whether a silver overcoat is an option that we can consider (we need to make sure that the short wavelength performance matches the needs of our users). Discussions of this topic remain ongoing.

-Open time
+As a reminder, because our summer shutdown was curtailed we have OPEN/DD time in August that can be requested. The early August time has been allocated, and although we have received several requests for the available time later in August, there is still some available. **UC reps please remind your users that they can request this time through the usual process** (submit requests to Russet, Nancy, Ben, and institutional scheduler, including a proposal cover page if the program doesn't already have one in place for Q3.

+The emails with the institutional allocations will be sent out later this week. We would like to know ASAP if any institutions expect to bring a class group to the site for training in Q4. This impacts our staffing schedule, for which we already have several constraints. //No one on today's call indicated that their institution is planning a class trip in Q4.//

-APO needs your help in updating the observatory publication record! Please send Nancy (nchanove@nmsu.edu) any references for 3.5m-related publications (refereed publications and student theses/dissertations that have been published or submitted) from Jan 1, 2021 to now. **The deadline was July 31 but Nancy can take all updates through the month of August.**

 Open action items from previous meetings:
-  * Nancy: start investigations re: short wavelength throughput (climate data, other facilities). Status: OPEN. 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.
