Norway Bathed In Northern Light Display

The Northern lights have put on a dramatic display in the skies above Norway as a result of a massive solar storm.

The lights - also known as the aurora borealis - were filmed near the Norwegian city of Tromsoe.
The display comes just days after Scotland and northern England witnessed the spectacle.
Although the general public has revelled in the natural phenomena, technical workers have been concerned about the display.
The Northern lights are known to disrupt communication systems, damage satellites and cause power blackouts at high latitudes because of intense solar radiation.

The solar storm has also caused havoc for some aviation companies.
US airline Delta diverted flights on routes across the polar regions as the radiation from the massive storm battered the Earth's atmosphere.
The event started late on Sunday with a moderate-sized solar flare that erupted near the centre of the sun, Doug Biesecker, a physicist with the National Oceanic and Atmospheric Administration Space Weather Prediction Centre said.
