Witness of an aerial phenomenon in 1975

Summary

On an evening in late summer of 1975, a witness observed an unidentified aerial phenomenon. While watching a sports match between Canada and the USSR on television, he went outside for some air and saw a bright circular object in the sky. The object was located to the east at an angle of approximately 70 degrees. Although the witness could not determine its exact altitude, he noted there were no clouds in the sky and believed the object was above ground level. He could not estimate its diameter, but observed that within 20 to 30 seconds, the green circle faded. Within minutes, several concentric green circles appeared around the object, which then disappeared without any sound or explosion. The witness had no opinion on the nature of the phenomenon and could not provide further details.
