 === Additional site, telescope and instruments discussion ===
-The 3.5m telescope is behaving nominally. The 0.5m is still inoperable; Bill recovered some spare parts from another site but the telescope still needs to be repaired. We anticipate scheduling ARCSAT observing programs no earlier than November.
+The 3.5m telescope is behaving nominally. The 0.5m is still inoperable; Bill recovered some spare parts from another site but the telescope still needs to be repaired. We anticipate scheduling Q4 ARCSAT observing programs to start no earlier than November.
 Through most of September ARCTIC had issues with the lower left quadrant of the chip being saturated. With the cooler weather that quadrant seems to have recovered itself. This recovery is not well understood; during some troubleshooting we swapped out a bunch of components but we still saw the issue. It was originally believed to be a problem isolated inside the cryostat but that is now less certain. For now we are in a "watch and wait" mode. This past weekend we saw evidence that there was water vapor stuck between ARCTIC's L2 and L3, which is a new problem to address. The purge air was on so it is unclear what caused condensation to form there.
-The inter-order light in ARCES had been slowly improving over the last few weeks but last weekend there was an inadvertent warm-up of the instrument. It is now offline with the hope that it will be back for tomorrow's scheduled observations. If we are unsuccessful, or if the vacuum has softened too much to cool it back down, we will need to take it offline for more extensive servicing. The salt and pepper noise that has been reported in ARCES frames is likely due to the new ICC, possibly the digitization card, a problem with the kernel, or the CPU board itself. This issue can appear any time, although recovery is quick. We are currently developing a procedure so the observing specialists can clear it up if seen.

 The annual APOLLO servicing visit took place recently. The NASA team was on site, but they did not complete their entire [ambitious!] task list. We expect they will return to complete the remaining tasks some time in 2027.

   * KOSMOS new grism - We have a revised quote from Wasatch; Sarah needs to complete her review of it and then we can order it.
-  * Ocotillo - Lab work is continuing, and we are planning for a pre-ship review by end of this quarter. We had a check-in meeting on 9/25 and discussed progress and expectations for the next review. Moire asked for spec sheet so that users could view the expected performance. Nancy reported that an Ocotillo report is being prepared for the ARC Board meeting, and a spec sheet will likely be included in that document. If it is, she will share it with this group.

   * ASPEN - Work on the ADC is moving forward. A request for funding was submitted for the ADC, and the ASPEN team is gearing up for another proposal submission next month.
   * SoonerCam - a focus group of prospective SoonerCam users recently met with Gordon to discuss modes of operation for the instrument. This will help him develop the instrument control software.

 === Plans for January AAS Meeting ===
-APO plans to have a booth at the next AAS meeting (sharing a double booth with SDSS). If any 3.5m users (especially students!) plan to present results that were abled through 3.5m observations we would love to know about it so that we can highlight the talks/posters at the meeting.
