| - | xxx | + | The weather at APO has been very monsoonal over the past month. September is going to be a busy month with two visiting classes, one from UWy (they were there in early September) and the other from UW, and two visiting instrument teams, The summer shutdown was completed and we are now back to normal operations. All routine shutdown maintenance activities were completed and the issue with the secondary mirror has not come back so hopefully it is resolved. Once again the 3.5m technical and operational staff did a fantastic job of conducting a successful shutdown and returning the telescope to science operations without a hitch. DIS servicing is currently scheduled for October. Ed Leon, the 3.5m electronics technician, retired on September 1. Nancy expressed her appreciation for his efforts and dedication to APO and the 3.5m over the past decade. The job ad for his position is now posted ([[https:// |

| - | xxx | + | 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 both flat fields and arc lamps, but since observers need to acquire arcs 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; |

| - | xxx | + | 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 we 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, |

There will be no on site classes in Q4. Several monitoring programs are requesting quarter nights in Q4. Users should copy Amanda Townsend (ajt@apo.nmsu.edu) in addition to Nancy, Ben, Russet, and their institutional scheduler on all schedule related emails. |

| + | The ARC Board of Governors meeting is on Monday November 7. Nancy, Ben, and some of the observatory staff are starting to gather the relevant data and prepare their presentations. | ||
| + | |||
| + | 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 for APO or ARC users. UC reps: please poll your users to see if they would be interested in an APO event (e.g. a meal or reception one evening) during the AAS meeting? One suggestion was to give out stickers to people with posters to indicate that they made use of APO data. Chip suggested that we try to connect those with undergraduates in attendance who are looking for graduate programs with representatives from other ARC member institutions, | ||

| + | 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! | ||
