Green meteor seen over the UK

[Black Monk]

People across the UK reported seeing a large greenish light streak across the sky on Sunday evening.

The source is likely to be a meteor – space matter disintegrating as it enters the Earth's atmosphere.

the colour is caused by the elements present in the meteor, there is nothing weird about it.

I saw a green one that split in two pieces one night, whole thing lasted 5 seconds or so, and was really cool.

As a simple element then Barium burns with a green hue. Barium is a common component in many different propulsion systems. This could have been part of a satellite re-entry or indeed, less prosaically, a meteor with a Barium component.

Actually the green colour is produced by nickel present in metallic meteoroids, meaning this was unlikely to be a piece of a satellite re-entering,

From the American Meteor Society:

The dominant composition of a meteoroid can play an important part in the observed colors of a fireball, with certain elements displaying signature colors when vaporized. For example, sodium produces a bright yellow color, nickel shows as green, and magnesium as blue-white.

May "also" be due to the presence of nickel in a meteoroid. Either interpretation of this event may be correct in the absence of definitive information. Either way it looks to have been something skimming the outer atmosphere

There was nothing in the opening post that stated it was unusual.
