Jednak to ziemskie pochodzenie mogło mieć związek z częścią widma radiowego wykorzystywanego do komunikacji między stacjami naziemnymi a militarnymi satelitami.
Ars contacted Nick Suntzeff, a Texas A&M University astronomer, for insight into what this signal at 11Ghz might be if it were not of alien origin. "If this were a real astronomical source, it would be rather strange," Suntzeff told Ars. Although there are mysterious, high-energy astrophysical phenomenon called “fast radio bursts” that are seen at a few gigahertz, they last only 10 milliseconds or so (this event lasted longer). Unfortunately, he said, there is no information given about the strength of the signal as a function of frequency.
Suntzeff added that he would not be surprised if the signal was due to a terrestrial origin, because it was observed in part of the radio spectrum used by the military. "God knows who or what broadcasts at 11Ghz, and it would not be out of the question that some sort of bursting communication is done between ground stations and satellites," he said. "I would follow it if I were the astronomers, but I would also not hype the fact that it may be at SETI signal given the significant chance it could be something military."
