Stargazers get rare glimpse of the Northern Lights

The Northern Lights has lit up the night sky with rare sightings across Gloucestershire.

The visibility of the aurora borealis was increased because of an "extreme" geomagnetic storm, according to the US National Oceanic and Atmospheric Administration (NOAA).

The NOAA said the G5 geomagnetic storm, which is considered extreme and is the strongest level of geomagnetic storm, hit earth on Thursday and could affect communications, GPS and power grids.

The cause of this storm is a "large, complex" sunspot cluster and is 17 times the diameter of earth, with the last storm with a G5 rating hitting earth in October 2003, causing power outages in Sweden.

The NOAA said the lights could be seen as far south as Alabama and southern California in the US.

Met Office spokesman Stephen Dixon said on Friday there was a good chance for the Northern Lights to be seen.

He said: "Although the shorter nights will limit the visibility window, there's a good chance to see the aurora, particularly on Friday night and especially in Scotland, Ireland and parts of northern England and Wales.

"There could even be visibility further south if you have the right equipment."

Mr Dixon said the combination of clear skies and enhanced activity from the sun reaching Earth would improve the chances of seeing the display.

Aurora displays occur when charged particles collide with gases in the Earth's atmosphere around the magnetic poles.
