Probable locations of extraterrestrial civilizations

The search for extraterrestrial civilizations by their continuous isotropic radioemission at the frequencies from 102 to 103 MHz is discussing. It is shown, what is a possible appearance of extraterrestrial civilization, which is accessible by modern means from the distance ∼ 20 pc at this frequency range. The search for similar radio-sources has been realized. Fortunately the such objects was displaied in the vicinities of the four solar-type stars, which are favourable for intelligence life. The probability of accidental projection of the radio-sources in vicinities of four such stars is only 2x10-4. These four stars are the promising objects for SETI
