Earlier it was reported a telescope possibly registered a signal from an extraterrestrial civilization sent from a stellar system in the constellation Hercules
ST. PETERSBURG, August 30. /TASS/. An unusual signal registered by the Ratan-600 radio telescope at the Zelenchukskaya observatory in the North Caucasus Republic of Karachay-Cherkessia is a terrestrial disturbance rather than a sound from an unearthly civilization, telescope researcher Yulia Sotnikova told TASS on Tuesday.

“Last and this year, the telescope’s work has focused on searching for sun-like stars,” Sotnikova said.
“There have been no scientific results within the framework of this research so far. Some time ago, in the spring of this year, an unusual signal was received but its analysis showed that it was most likely a terrestrial disturbance,” she noted, adding that the observatory was preparing the text of an official disclaimer to dismiss media reports on the discovery of a signal from an unearthly civilization.
Director of the Institute of Applied Astronomy at the Russian Academy of Sciences Alexander Ipatov told TASS that back at the Soviet period he had been part of a group of young astronomers at the special astrophysical observatory searching for signals from extraterrestrial civilizations.
“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,” Ipatov said…. READ FULL ARTICLE
Here is the official comment from SAO RAS regarding the radio signal associated with HD 164595:
On August 30, 2016 there appeared a number of reports in different mass media on possible detection of a radio signal at RATAN-600 associated with the activity of an extraterrestrial civilization; in this connection, we consider it necessary to make official comments.
In the last few years, the astronomers of the Skobeltsyn Institute of Nuclear Physics of Lomonosov Moscow State University together with their colleagues from the Special Astrophysical Observatory of the Russian Academy of Sciences (SAO RAS) have been conducting a survey of astronomical objects in the framework of the SETI (Search for Extraterrestrial Intelligence) program. SETI is the common name for projects and activities for the scientific search for activity of extraterrestrial civilizations. The program is oriented towards searching for radiation of possible artificial origin. The studies are carried out with RATAN-600 using wide-range continuum radiometers in the frequency range of 1-22.7 GHz. Such observations at RATAN-600 are made possible owing to its large collecting area of thousands of square meters, and this high sensibility of the telescope allows us to search for extremely weak signals in the Universe, to which SETI objects also refer. The objects of research within this program are solar-like stars with planets and solar-like stars with possible non-detected planets.
In the framework of this program, an interesting radio signal at a wavelength of 2.7 cm was detected in the direction of one of the objects (star system HD164595 in Hercules) in 2015. Subsequent processing and analysis of the signal revealed its most probable terrestrial origin.
As for the other objects of the RATAN-600 survey, it is too early to claim about any reliable scientific results. Using the obtained measurements, we are only able to estimate the upper limit of the detection of the studied areas. It can be said with confidence that no sought-for signal has been detected yet.
