-Over summer shutdown several KOSMOS-related tasks were accomplished. We reduced the brightness of the internal calibration lamps by putting an ND filter in place. This will affect flat fields and arc lamps, but since observers need to acquire those more frequently because of the known instrument flexure we don't want to dim those any further. We are recommending that observers use truss lamps for flat fields if the frames are still saturated. We are currently trying to see if we can address the brightness of the internal quartz lamps but not the arcs, which requires a tradeoff between the needs of narrow vs wide slit observations; no decisions have been made yet. We are optimizing the system for good arc lamp exposures for the moment. A new shutter was installed in the slit viewer camera. We hope to have the new slits from the UW shop by the end of the month. Nancy posted some info to the wiki concerning how some have been handling the flat fielding of KOSMOS data (see [[:kosmos|]]). We have gone through just about one entire cycle of seasonal changes with KOSMOS, so we are now developing a more complete understanding of its behavior with environmental changes. The multi-object capability is still coming; we hope to do some more testing during engineering time soon. +Over summer shutdown several KOSMOS-related tasks were accomplished.

-The problems that we had been having with the secondary mirror have not been recurring since shutdown; we hope it was resolved by the change in hardware that was made during shutdown. We are still vulnerable to a possible recurrence of the tertiary problem had a few months ago but this is not a frequent issue so we hope it will not recur, The telescope came back together nicely after shutdown and we had good luck during the initial part of the shutdown recovery period. We expect to have good pointing with all instruments,+The problems that we had been having with the secondary mirror have not been recurring since shutdown; we hope it was resolved by the change in hardware that was made during shutdown.

-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, We discussed options for doing something special to denote APO or ARC users. One suggestion was to give out stickers to people with posters to indicate that they APO data, chip those with undergrads looking for grad programs, small recruitmentMisty start Google Doc where ppl can list their APO-related posters and talkswould help w/exchangeAbstract deadline coming up.+The January 2023 AAS meeting will be 8-12 January in Seattle.

Chip suggested that we try to connect those with undergraduates in attendance who are looking for graduate programs with representatives from other ARC member institutionsas a small-scale recruitment effort. Misty suggested that we start Google Doc where people can list their APO-related posters and talks; this would help with connecting peopleThe abstract deadline for the meeting is Tuesday October 11!
  
-Later: need help w/booth+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!

-  * 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.+  * Nancy: start investigations re: short wavelength throughput (climate data, other facilities).
