 Nothing new on ARCTIC. Echelle - working on steamlining reaction software for calculating IOL; discovered that DATE-OBS keyword was wrong (45 min in the future from when image was written) - then did some data mining; this occurred in late August 2024 but not caught until now. If time steps are important for your echelle observations - ARCES observers should take note and we can provide the detailed time offset for anyone for whom this is critical. Report by a user a few weeks ago that new Th Ar bulb replaced in July 2025 had some weak/missing Ar lines in blue orders. We replaced with a different spare - did this on Sep 29. On Sep 30 reports that the new bulb was slightly fainter than bulb a year ago. Reduction process is more efficient now. Users should also note this. Hollow cathode lamps - can no longer obtain Th metal filaments; increasingly hard to find on the shelf. We just purchased some supply so that we have spares - hope that each one will last a few years each. Becoming harder to find old style THAr lamps. Alternative source may need to be identified. Nothing new on ARCTIC.

-The Q4 schedule is posted.+The Q4 schedule is posted. Fair amount of OPEN/DD01 time in late October (dark). All B halves. Hoping to use it to pay back some of the KOSMOS users but not committing until know when KOSMOS returning. Some of KOSMOS time may need to be allocated to other users. Ideally from same institution. Additional OPEN/DD01 time later in quarter, including limited number of A halves or partial A halves. Thank you Russet for doing such a good job with the challenges for this quarter.

-The ARCSAT Q4 schedule is posted.+The ARCSAT Q4 schedule is posted. Pretty full, but this week is open (rest of this week). Some other time available later in the quarter. Two instruments are UVa-cam (larger FOV), Dcam-spare, smaller FOV and less oversampled but Dcam-spare did have some frost after shutdown; gone now but see signatures on detector; they flat field out but looks ugly when takking data.

-  * SoonerCam: xxx+  * SoonerCam: parts have been trickling in. Received fiber, software dev kit. Waiting on fiber to coax press converters, arriving today? Not computer yet. dig in after november
   * 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 (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.
   * ASPEN: We recently learned that a proposal we submitted for funds to support the development of the new echelle spectrograph was not selected for funding. Work on the design of the new optical echelle spectrograph continues with the goal of completing the Preliminary Design Review in early spring 2026.   * ASPEN: We recently learned that a proposal we submitted for funds to support the development of the new echelle spectrograph was not selected for funding.

-  * Ocotillo: xxx+  * Ocotillo: Now have vibration stabilization and optical table are in house, enclosure too. Started to get optical mounting parts. Student working on software and data side. late this week fibers are coming. Optics are coming in next few weeks (end of the month) including the grating by mid-November (ahead of schedule?). Submitting an ATI for robot side of channel.

 The next meeting is currently scheduled for Tuesday November 4, 2025. This directly conflicts with the ARC Board meeting; shall we reschedule for one week later or cancel the November meeting and meet again in December? The next meeting is currently scheduled for Tuesday November 4, 2025.

 +Gordon - working on new release for TUI - v3.2 - plans to get it out soon. Had some instruments decommissioned, cleaned out old scripts. Most exciting aspect is working on packaging to make install process more simple for users, especially students. Get the changes automated to be download to Git Hub. Prev versions will still work but encourage uses to keep updated.
