Leningradskaya oblast

Alexander Tomashevsky writes to the Commission on AI:

I was prompted to write this letter by the article "Exactly at 4-10", published in the newspaper Trud for 30.01.85.

The incident that happened to me and my friend at that time did not attach importance.

They served in the Leningrad region in the village of Vaganovo. In April 1982, we had to carry out the commander's task. We went at night to the village of Kokoreva (I can't remember the exact time now, something around 11-30 - 01-30) located on the shore of Lake Ladoga. Coming out of the forest, we noticed a large green-blue spot in the sky. It stood out clearly against the dark sky. The spot smoothly changed shape, now bulging out in the form of an ellipse, then taking the shape of a circle, barely noticeably moving.

We walked for 15-20 minutes, during which time the spot shifted by about 20-25 degrees. We returned about 40-45 minutes later, we observed it again, but it began to fade. I assumed it was a reflection of the lake.

What happened to the stain then, I do not know. but I remember him well.


List of versions containing features matching the eyewitness descriptions or material evidence

Light sources on clouds

Lasers, searchlights, car headlights and other light sources of sufficient power can form a column of light in a dusty or foggy atmosphere, various patterns on low clouds, fog or haze. Also, the rays can highlight parts of the cloud, objects or birds, giving them bizarre shapes.

Searchlights can shine with one beam, several. They can be stationary, move, and also form spinning carousels on the clouds, which can change shape and color.

It often seems that the light source is located at the point where the beam hits the cloud, and not vice versa.

Booster, the rocket and tracks

For UFOs often take stages of rockets, parts of space ships burning in the atmosphere, the launches of various missile technology for military purposes, etc., and traces from them. They attract attention mostly in the dark, but in the day time have a greater aura of mystery.

Formation of the track of the launch vehicle occurs in the tropopause (the layer between the troposphere and stratosphere), which sharply reduced the vertical temperature gradient. The emergence of the so-called "jellyfish" influenced by water vapor, which are subject to enhanced condensation.
