>BLC1 is a candidate SETI radio signal announced in December 2020, possibly coming from the star Proxima Centauri.[1][2] The signal has a frequency of 982.002 MHz[3] and an apparent shift in its frequency is consistent with the Doppler effect caused by the movement of Proxima b, a planet of Proxima Centauri.[4]
>The radio signal was detected during 30 hours of observations conducted by Breakthrough Listen through the Parkes Observatory in Australia in April and May 2019.[5] As of December 2020, follow-up observations have failed to detect the signal again, a step necessary to confirm that the signal was a technosignature.
