Title: Did the radio signal BCL1 come from Proxima b?
Post by: alfa015 on 25/12/2020 15:42:45

Hello,

Merry Christmas to everbody!

At The Exoplanets Channel in YouTube we made a video-analysis at about the possible origin of BLC1. Basically:

-BLC1 has a frequency of 982 MHz, which does not seem to be used by any of the satellites orbiting the Earth.
-In Australia, the frequencies from 960 to 1,164 MHz are reserved for aeronautical mobile and radio navigation.
-The frequencies from 979 to1024 MHz are employed in military systems such as the Joint Tactical Information Distribution System and the Multifunctional Information Distribution System.

We basically conclude that the radio signal could have been produced by a military aircraft, but more information is needed to confirm this.

What's your opinion about BLC1? Human interference or alien origin?

It's possible for radio-communication signals to be reflected, & (doppler) shifted,
by the metal body of fast-moving aircraft, (inadvertent radar),
