| 1 student visit last month, closed 2 nights due to ice on enclosure. | There was one student group that visited last month. We've had some winter weather and were closed for two nights due to ice on the enclosure and lightning arrestors. |
| Instruments- KOSMOS and ARCTIC each had some problems. KOSMOS - when commanded the disperser wheel sometimes gets stuck - operator runs up and moves it by hand - happened once. Had another instance where camera focus wasn't set and caused confusion re: telescope focus - happened once and was corrected. Failures of UW manufactured silicon wafer slits - stress cracks likely due to differential expansion of aluminum holds. Need to identify manufacturer for new spares/replacements. | |
| ARCTIC - failure of filter wheel - caught in afternoon so didn't affect observing - recovery was more difficult than usual for night staff - engineering staff assisted. Instrument exposure was stuck and couldn't do more - init done, caused dropped quad, user used single amplifier for the rest of night. More serious issue with ion pump and loss of vacuum to instrument. Failure of high voltage cable - welded to pump, needed to replace pump and cable. Brought back - thanks to Cary who came in over time off during break to restore instrument. First biases were achieved with new SoonerCam setup. Starting to develop new ICC software and trying to learn lower level commands for triggering camera. Preliminary but noteworthy that got camera biases. Intemritten failure of ThAr lamp power supply for ARCES - cleaned and did temp cleaning. Users should still check exp to make sure have enough DIS decommissioning continues, decabled but on flor - on going, No issues with TSpec or NICFPS, APOLLO working well. | As for instruments, both KOSMOS and ARCTIC each had some problems last month. There was an instance when the KOSMOS disperser wheel was commanded and then got stuck; this was remedied by the operator going up to the observing level and moving it by hand. We had one instance where the camera focus wasn't set properly and caused confusion regarding the telescope focus; this was corrected. We've seen some stress cracks in the UW-manufactured silicon wafer slits, likely due to differential expansion of the aluminum holders. We are working to identify a manufacturer for new spares/replacements. |
| Noted about Harry Abbot hire. | |
| Site infrastructure review | ARCTIC had a failure of the filter wheel; this was discovered by an observing specialist in the afternoon and fixed by the engineering staff that same day so it did not impact observing. We had another instance where the instrument exposure was stuck and could not be commanded to take another. An init was done, which caused a dropped quad, and the user elected to observe in the single amplifier mode for the rest of night. We had a more serious issue with an ion pump that resulted in loss of vacuum to the instrument. This was due to a failure of a high voltage cable that became welded to the pump; both needed to be replaced. Special thanks for Cary Smith who came in during his time off during the winter break to restore the instrument. |

| | First biases were achieved with the new SoonerCam setup. We are starting to develop the new ICC software and trying to learn the lower level commands for triggering the camera. |
| | |
| | We've seen an intermittent failure of the ARCES ThAr lamp power supply, We cleaned the connectors and this seemed to help but the issue still sporadically appears.** Users should check their ThAr exposures to make sure they have enough lines with appropriate S/N levels.** |
| | |
| | DIS decommissioning continues; the instrument is decabled but still on the observing floor for now. |
| | |
| | There have been no issues with TripleSpec or NICFPS, and APOLLO has been working well. |
| | |
| | We have completed hiring process for a new Support Astronomer (observing specialist). Harrison (Harry) Abbot will begin his work and training in a few days. |
| | |
| | There will be a site infrastructure review held at APO next month. The goal is to review overall site and telescope infrastructure items (excluding instruments) in order to develop priorities for resource allocation in order to ensure that we maintain a highly functioning observatory. |

| * SoonerCam: Nearly all of the parts we are expecting have come in. We will begin working on this in January. | * SoonerCam: See above site report and subsequent discussion. |
| * KOSMOS grisms (no change from last month): we are still awaiting a decision on the proposal we submitted for funds to support the purchase of three new grisms for KOSMOS. | * KOSMOS grisms: our proposal requesting funds to support the purchase of three new grisms for KOSMOS was not selected. We will move forward with the purchase of one or two grisms using ARC funds. If users have an opinion about this they should complete the following form **no later than Friday January 30**: https://forms.gle/Fr6LVu9o8Up782hW7 |
| * ASPEN: NSF pending, state of NM funds, AAS poster, SPIE papers, PDR in Q2 | * ASPEN: we have an NSF proposal pending but learned that we did receive some funds from the State of New Mexico to further advance the design. We will move forward with building the atmospheric dispersion corrector first since it can be used with ARCES. We presented a poster about ASPEN at the Jan. 2026 AAS meeting and received some positive feedback, and we submitted several papers about the instrument for the SPIE conference this summer. We still plan to hold the Preliminary Design Review in the first half of 2026, likely now in Q2. |
| * Ocotillo: Progressing, camera characterization, software, have grating and few optics and fiber in hand, functional shop, lab manager leaving/hiring to replace, BS/MS position. | * Ocotillo: Things are progressing; we have the camera in hand and someone is working on camera characterization and software. We have the grating, some optics, and the fiber in hand. The TEG will be hiring an engineer/technician at the BS/MS level very soon; interested parties should look for the job ad on the UW hiring site shortly. |

| Schedules are linked from old web site - sort out certs, working by end of today. | We flipped the switch this morning so that https://mainapo.apo.nmsu.edu became https://www.apo.nmsu.edu. This resulted in some preliminary problems as some certificates needed to be updated in order to preserve the old web site (which will be located at legacy.apo.nmsu.edu). We hope to have these sorted out by the end of the day. The links to the observing schedules are currently not working, but one can still access the Q1 schedule using this direct link: http://35m-schedule.apo.nmsu.edu/2026Q1.shtml. Shane will fix Aleksandr's reported issue ASAP. If users have difficulties finding what they need on the new site please let us know ASAP! |

| Nancy presented a subset of slides from her presentations to the ARC Board of Governors meeting in early November to provide the UC reps with a summary of the 2025 operations, science achievements, and plans for next year. | We had a booth alongside SDSS and SciServer so there was a strong APO presence at the Jan. 2026 AAS meeting in Phoenix. We were well positioned in the exhibit hall and received a lot of foot traffic; we gave away a lot of swag. |

Update: Nancy connected with the folks working on this while at the AAS meeting so we are getting closer to have this software in hand and made available to the user community through the wiki. Status: OPEN. |

Status: CLOSED. | * UC reps: please discuss the idea of archiving our 3.5m data with your users and report back with any reactions, either positive (e.g., advantages that they see to having a data archive) or negative (e.g., potential issues or concerns). No UC reps reported any feedback from users so we will be moving forward with piloting this as a next step. Status: CLOSED. |
