| - | xxx | + | We've had monsoonal weather at the observatory. The secondary mirror issue may be resolved since a board was replaced in the controller that moves the actuator on the back of the mirror. This was an old board and we are working on preparing for potential future failures. There has been some testing of MOS capabilities with KOSMOS. DIS is tentatively scheduled for servicing on red camera in early October. Everything else is nominal. |

| - | xxx | + | The KOSMOS activities that are planned for summer shutdown include the following: |
| + | * replace shutter in slit viewer camera with a new one that is rated for operation at colder temperatures | ||
| + | * try to resolve internal cal lamp brightness issue (again) by lowering the brightness of lamps with ND filtering | ||
| + | * a user is trying to use KOSMOS for bright planetary work with ND filters that are screwed on, but it was discovered that this results in interference with the cal stage. We will attempt to address this, possibly by removing some material from edge of the cal stage itself. | ||
| + | * if time allows, we will warm the instrument, pump on it, and bake out the getter | ||

| + | As a status update on the MOS capability for KOSMOS, Bill got the KMS software running under certain operating systems; he can provide instructions on how to install it. He has been working with Joe Burchett at NMSU on streamlining the process; currently the software outputs files in a format that is used for making electronic boards but not used by many machine shops so Bill has been converting them to SolidWorks or AutoCAD. We've had a few slit masks made at the UW machine shop using a wire EDM but this is expensive. We attempted to have some made at the NMSU machine shop using a laser cutter but the results are of low quality. However, in both cases we found that the scale factor between the slits and the sky is off by a small amount, so we are iterating on that to get the slit positions to match on-sky coordinates. Bill has also been working with former KOSMOS folks at NOIRLab to work out the intricacies of setting up the software configuration files to make it more applicable for APO. We are hoping by mid-September to have the process streamlined to help users create slit masks for multiobject spectroscopy. UC reps should remind their users of this exciting new capability at APO! | ||

| - | xxx | + | Last month we discussed the fact that we have to delay the realuminization of the primary mirror due to the Contreras Fire at Kitt Peak. We are still actively pursuing other options, including whether a silver overcoat is an option that we can consider (we need to make sure that the short wavelength performance matches the needs of our users). Discussions of this topic remain ongoing. |

Nancy reached out to some colleagues at other observatories to ask about short wavelength performance degradation of their optical coatings. She got some names from Bill and will contact those individuals next. The ongoing discussions about new coatings for the primary also relate to this issue so we will determine our coatings first before continuing to pursue this line of investigation. |
