Employees of LINPO "Paint and varnish coating" write to the Commission for the AIA of the USSR:

We would like to inform you that on December 6, 1985, at about 19-00, at the Svetlana plant in our city, we observed an unusual phenomenon: against the background of a dark sky - a huge glowing disk of a pale greenish hue, surrounded by a rainbow of colors around the entire diameter.

We watched it for about 5-6 minutes, after which the disk slowly crumbled and disappeared. Please let us know if a similar phenomenon has been observed anywhere else, what the causes of its occurrence may be, and also find out if this phenomenon may be related to your article "Exactly at 4.10".

The Aurora (Northern lights)

Glow (luminescence) of the upper layers of the atmospheres of the planets with the magnetosphere due to their interaction with charged particles of the solar wind.

In a very limited area of the top of atmosphere radiance can be caused by low energy charged particles of solar wind entering the polar ionosphere over the North and South polar Caspi. In the Northern hemisphere, the cusp auroras can be observed over Svalbard caribou watch.

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.
