HD 164595 - Wikipedia
On 15 May 2015, a brief, single radio signal at 11 GHz (2.7 cm wavelength) was observed in the direction of HD 164595 by a team led by N. N. Bursov involving Claudio Maccone at the RATAN-600 radio observatory. The signal may be due to terrestrial radio-frequency interference or gravitational lensing from a more distant source. ...
