Radio Signal From Direction of Proxima Centauri

[ProxCenBound]

Okay, so all of that appears to be unrelated to the Breakthrough Listen candidate, though certainly of interest in its own right. The links I posted above are about a narrowband signal which has not been written up in any scientific paper yet, not even on ArXiv. It was apparently leaked to the Guardian, and then a more detailed treatment appeared in Scientific American (which I linked above) and later in National Geographic: https://www.nationalgeographic.com/scien...arby-star/

I think it is artificial, but from our own technology somehow. That is also the leading hypothesis by Breakthrough Listen, but they are trying to rule it out.
