+Hard time with ARCSAT the other night (Chrome requiring permission... older version of Chrome and Mac OS... two users using same port, which again, worked with older version).  Sarah notes that they have had 10 users on the same port without problems in the past.  Shane is aware this problem occurred, but may want to loop in Gordon.
+APOLLO got returns during the eclipse, so is functioning well.

   * KOSMOS grisms: We have requested an updated quote for the low-res grism and will be ordering it as soon as it is received.
   * ASPEN: No major updates this month. We still plan to hold the Preliminary Design Review in Q2 2026.

+Met with Jon and Anne to discuss improvements to landing pages, and simplification of menus to improve public facing pages and make most popular information easier to find.
+UCO found some broken links.  Will send to Shane or Ben to get fixed.

   * Joanne Hughes: put the KOSMOS MOS data reduction software on the wiki. Joanne is waiting for an update from her colleagues at the College of Idaho. Update: Jon Holtzman put a link to the College of Idaho software on the wiki, and notes that this is a wrapper for lower level reduction stuff in pyVista. Additional descriptive text/examples would still be welcome and good. Status: CLOSED
   * UC reps: ask your users to provide instrument usage/data reduction tips and tricks to Jon Holtzman for inclusion on the wiki.
+No feedback yet... STILL OPEN
   * UC reps: ask your users if they have experience using PypeIt with non-APO instruments; if so please contact Jon.
+No one knows anyone... may want to close?
   * Nancy: ensure that observatory lat/long/elevation gets put back on new APO home page. Status: CLOSED
   * Nancy: explore web page hackathon idea with APO webdev team. Status: CLOSED

 New action items from this meeting:
+ARCSAT issue should get checked out to attempt to determine cause or see if it can be reproduced.
+Adam noted some ghosting effects he's seeing in bright object KOSMOS spectra.  He may send in some examples of ghost spectra for KOSMOS documentation, and potentially could take some bright object spectra during engineering to learn more about these effects.

 === All Other Business ===
-None.
+Grisms:  Any update on high res prisms?  Low res was easy to decide, but high-res is harder because one needs to choose the part of the spectrum, and there is not consensus.
+KOSMOS: Zeroth order effect could use more information (how it manifests in various setups).  Adam is seeing ghost spectra in some spectral setups.  Is there anything about this in the documentation?  Suggestions for order-blocking filters?  Not available if you want to observe in the blue, and may actually cause reflections.  More information about those would be appreciated.  Added an action item.
