On 2019 April 29, the Breakthrough Listen SETI project observed Proxima Centauri with the Parkes ‘Murriyang’ radio telescope. These data contained a narrowband signal with characteristics broadly consistent with a techno signature near 982 MHz (‘blc1’)
The signal appears to have originated from the direction of Proxima Centauri. It has been given the name Breakthrough Listen Candidate 1 (BLC1). As of December 2020, the researchers were still working to rule out terrestrial interference. One researcher called it "on par" with the Wow! signal.
