The path itself misses us, far to the north. But the rings are a possibility. This is a very big ask... the rings of Quaoar have little opacity, so far as we can tell. And the altitude is only 14 degrees above the SE horizon. This will make the star 0.8 magnitudes dimmer than if it were at 66 degrees altitude. The extinction by the atmosphere and the twinkling will make this event I believe nearly impossible. 15.7 mag will then look like W=16.5. 3 magnitudes dimmer than a 13.5. A 13.5 star would, I'd estimate, an integration of 16x to be adequately visible to hope to see a partial occultation by rings. 16x or 1/3 second. But 3 magnitudes dimmer would then require 15.8 times more integration or 5.3s. That's longer than the maximum 256x = 5s integration for the PAL Watec, possible by the Watec. Even so, would 5s be too long to show the occultation by the denser ring?
John Irwin's observation of the ring1 gave a total occultation length of 1.1s, with most of that interval being a shallow partial occultation. So it would seem that a 5s integration would not see any detectable signal. In a 10" we might get away with 2.5s integration, but that's still not going to detect the occultation.
The ring geometry will probably be quite similar to the May '23 event, at a similar place in the local sky and same constellation.
