Location: Moscow, Russia.

Time: 15:17.

A woman was ironing some linen next to a window when she casually glanced outside. She was astounded to see right outside the hovering in the air the image of a woman wearing a Greek dress with her hair combed back. She called her husband. Both now saw the profiles of a man and a child near the woman. The images appeared to be volumetric. Unexpectedly from the head of the woman a symbol resembling a semi-circle and an arrow pointed directly upwards appeared. Also the letter D from the Russian alphabet also appeared, and under the image of the child what appeared to be the Greek alphabet. The children now appeared and excitedly exclaimed that it was an animated cartoon. Having regained his composure the husband began to open the window slowly and the images suddenly turned pale, dimmed and vanished. Soon after this peculiar incident others in the area reported a series of observations of UFOs and other phenomena.

I've been researching this topic for some time, collecting over 30 cases like this one. This ancient aerial phenomenon gradually disappeared over time, though it was very active in Russia between 1990 and 2000.

For those asking, yes, there is evidence of these apparitions; only one is publicly available, the rest belongs to the Russian Ufological Group Kosmopoisk.
