I tell you what something is happening and it has seriously piqued my interest. The methods being discussed about the potential discovery make complete sense. I do sense a lot of caution is being taken, because everything has to be ruled out but I predict this story making major waves in the months to come. I wouldn’t normally post info from Simon Holland, but the specifics of what he is discussing has validity.
TL:DR
In 2019, the Parkes radio telescope detected a signal that seemed to come from the Alpha Centauri system, specifically Proxima Centauri, which hosts an exoplanet in its habitable zone. Initially dismissed as interference, recent analysis by Astron, a European Space Agency-funded group, suggests the signal could be a legitimate technosignature of extraterrestrial origin. This is Holland’s claim. The signal showed a Doppler shift, indicating movement, and doesn't match any known natural phenomena. While Astron hasn't published full research, there's speculation they may be waiting for SETI, which is cautious about non-repeating signals. Rumors suggest China is also investigating the signal.

Just some background: The Alpha Centauri system consists of three stars orbiting one another, with Proxima Centauri being the smallest and most distant from the other two. In addition to Proxima B, the system contains two other confirmed exoplanets, potentially increasing the likelihood of life developing in the region.
Initially, the signal's legitimacy was questioned due to its resemblance to background noise and potential interference from human-made radio transmissions. However, claims are it has now been verified as a legitimate technosignature. The thing is Proxima Centauri is a controversial topic because its solar flare activity could strip away the atmosphere of planets in its orbit.
Apparantely Astron has since conducted a more detailed analysis of the signal. This signal was initially discarded in 2021 due to its weakness, despite appearing to be extraterrestrial in origin. Now with the development of phased array multiplex technology utilizing multiple satellite dishes, Astron was able to amplify and further examine the signal, consolidating data from multiple radio dishes across the globe.
The claim from Simon Holland is that Astron has now confirmed the signal's extraterrestrial origin and has allowed him to share their involvement in the study. The signal displayed a Doppler shift, indicating that its source was moving away from the Parkes radio telescope at the time of detection, pointing to an interstellar origin. Although the exact location remains uncertain, the signal's narrow-band characteristics make it unlikely to be a result of human interference
Even though the signal bears some traits of a natural source, it doesn't align with any known natural phenomena. The proximity of the Proxima Centauri system to Earth adds to the intrigue, as the usual suspects for such signals, like pulsars or magnetars, are absent in this region. Although Astron has yet to publish its full research on the signal, speculation is that they may be waiting for SETI to make an announcement. Problem is SETI has traditionally been cautious about reporting signals that haven't repeated. Still there is a possibility that Astron has detected additional data on this signal that hasn't yet been shared.
The fact is this, Astron, a highly respected institution backed by the European Space Agency chose to share more detailed analysis with Simon Holland. Why?? Why would they risk that? Also why are they not denying his claims? Also rumors are the Chinese are reportedly conducting their own research on the signal, which may prompt SETI to move quickly to avoid being overtaken. Either way take note because something will shake out from this.
