When you go to you-tube and look at all the videos of this, something isn't right. All sorts of different angles and colors are to be seen. Flying across the sky and flying directly down.

The mere fact that no respectable explanation of what it was has been disclosed other than it could of been space debris is ludicrous considering the amount of ... well you get the gist.

________ Media says______

Sightings of bright objects passing through the night air were made across many parts of Scotland and Northern Ireland.
They were reportedly also spotted in parts of the West Midlands and Norfolk - but experts can't pinpoint what the phenomenon was.
Brian Guthrie, from Grangemouth, Scotland, told the BBC it looked like something: "pretty large breaking up in the atmosphere.
"I've seen shooting stars and meteor showers before, but this was much larger and much more colourful."
There were several meteor showers expected to happen in September, but astronomers say last night's spectacle was not one of those.
Colin Johnston, from Armagh Planetarium told the BBC: "There are actually several small, faint, meteor showers scheduled across September but they're so unspectacular, not many people actually bother looking for them.
"I think that actually this spectacle tonight might not be associated with that.
"I think it's something just by chance has happened to come in tonight, some piece of actual space junk floating around the universe for billions of years has just picked tonight to fall in across our skies or some satellite that's been up for some years has decided to burn up."

There are many more videos on this. Sorry if this has already been posted.

Interesting. A Green or Blue colour represents a high Magnesium content.
Goddamnit, why do I always miss these things.

METEORS: Meteors are better known as "shooting stars": startling streaks of light that suddenly appear in the sky when a dust particle from outer space evaporates high in the Earth's atmosphere. We call the light phenomenon in the atmosphere a "meteor", while the dust particle is called a "meteoroid".

Size: Most visible Leonids are between 1 mm and 1 cm in diameter. For example, a Leonid meteor of magnitude +5, which is barely visible with the naked eye in a dark sky, is caused by a meteoroid of 0.5 mm in diameter and weights only 0.00006 gram.
Speed That tiny particle can cause a light so bright that it can be seen over distances of hundreds of kilometers. The reason is the astronomical speed of the meteoroids. Just before they enter the Earth's atmosphere, Leonid meteoroids travel at 71 kilometers per second, or some 2,663 times as fast as a fast pitch in baseball, or, if you want, around the Earth in 3.8 minutes!
Source of light When meteoroids enter the Earth's atmosphere, they collide with numerous air molecules. Those collisions sputter away the outer layers of the particle, creating a vapor of sodium, iron and magnesium atoms. In subsequent collisions, electrons are knocked into orbits at larger mean distances from the nucleus of the atoms. When the electrons fall back to their rest positions, light is emitted. This is the same process as in gas discharge lamps.


Colors of meteors The color of many Leonids is caused by light emitted from metal atoms from the meteoroid (blue, green, and yellow) and light emitted by atoms and molecules of the air (red). The metal atoms emit light much like in our sodium discharge lamps: sodium (Na) atoms give an orange-yellow light, iron (Fe) atoms a yellow light, magnesium (Mg) a blue-green light, ionized calcium (Ca+) atoms may add a violet hue, while molecules of atmospheric nitrogen (N2) and oxygen atoms (O) give a red light. The meteor color depends on whether the metal atom emissions or the air plasma emissions dominate.
Sounds Meteors do not normally cause audible sounds. Hence, they will pass by unnoticed if not seen. But watch out for hissing sounds that have been reported for very bright meteors. These sounds are thought to be due to very low frequency (VLF) radio waves interacting with the local environment. A sonic boom is sometimes heard for very bright Leonid meteors, called fireballs, that appear near your own observing site high in the sky. If the particle is larger than the mean free path of the air molecules, a high Mach number shock wave forms in front of the meteoroid. Very rarely, this shock wave penetrates deep enough in the atmosphere that it can be heard. It sounds like the sonic boom of an airplane, but as a distant rumble.

Mods can you merge again. I think this threads title has a better description. my thoughts
