| - | xxxx | + | 3 class visits in Oct-Nov, upcoming class at end of this week, current training responsibilities transferred over to Russet and Amanda. |
| + | |||
| + | 3.5m telescope - working fairy well. Still have occasional motion error (seasonal), haven' | ||
| + | |||
| + | 0.5m Dcam-spare - cleaned to remove water spots but without much success. Likely going to replace DIS slitviewer to use in ARCSAT. UVa camera still available. Not much luck testing BYUCam - may send to Fingerlakes for repair/ | ||
| + | |||
| + | KOSMOS - repaired cold strapping in a temporary sense - constrained wired cold straps put back in place because unable to get braided copper straps to properly silver solder. Engineering last night - did some additional dark testing to make sure that it's still holding up as a fix; some dew on cryostat window due to lack of purge air turns on when put back together, They dried up. During Q1 will warm and pull cryostat to clean window. Should flat field out in the mean time and are barely noticeable. | ||
| + | |||
| + | ARCTIC had problems with vacuum / cryostat ion pump. one instance with filter wheel unable to be commanded. Restarted hardware controller in November. | ||
| + | |||
| + | Agile not taken apart yet but have received all parts for SoonerCam but will start assembling it after first of year as well as software developing. | ||
| + | |||
| + | ARCES - reminder about FITS header DATE-OBS keyword was incorrect. Also - in last week had some intermittent THAr lamp behavior - not energized. Recent echelle users should look at their cals to confirm that cal files are not blank. DOn't think it's a bulb problem, probably cabling or power supply. Still investigating. | ||
| + | |||
| + | APOLLO - had 2 sessions in last 2 months where hit all 6 retroreflectors. And tracked down some water line problems identified and repaired. | ||
| + | |||
| + | Moire question: is ARCES value offset constant or does it depend on when data were taken? BK: thinks it's constant. | ||
| + | |||
| + | KOSMOS - plan to remake some of the parts for cryostat separately so that servicing time is minimized. | ||

| - | The Q4 schedule is posted. There is a fair amount of OPEN/DD01 time in late October (dark time, all B halves). We hope to use some of it to pay back KOSMOS users who had to give up their time but we're not committing to that until we know when KOSMOS will be returning. Some of the scheduled KOSMOS time may need to be allocated to other users, ideally from the same institution. There is additional OPEN/DD01 time later in quarter, including a limited number of A halves or partial A halves. A huge thank you to Russet for doing such a great job with the challenging schedule for this quarter. | + | The Q4 schedule is posted. |

Work on the design of the new optical echelle spectrograph continues with the goal of completing the Preliminary Design Review in early spring 2026. We are hosting an ASPEN team meeting at APO and NMSU this week. | * 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.
