The signal had come from the same direction as the star system HD164595, which sits in the Hercules constellation and has a star that’s comparable to our Sun. But Shostak’s SETI colleagues were unable to detect the signal, and in an update to his original blog post, Shostak says that both Russian news agencies and the Russian Academy of Sciences have concluded that the signal “is, indeed, terrestrial interference.”…

A report by the Russian news agency Tass suggests that the signal might have come from a Russian military satellite.

Without directly connecting the signal to that satellite or providing details about it, Tass quotes Alexander Ipatov, the director of the Institute of Applied Astronomy at the Russian Academy of Sciences, as saying that during the Soviet era, “We, indeed, discovered an unusual signal. However, an additional check showed that it was emanating from a Soviet military satellite, which had not been entered into any of the catalogs of celestial bodies.”
