In Pictures: Webcam captures stunning Northern Lights in Sweden

The Northern Lights were captured by tour company Lights over Lapland's aurora webcams.

“Believe it or not, the auroras started quite early this season and we have already had more than a month of powerful displays. Which has got us all excited about the upcoming winter,” said Abisko-based photographer and tour guide Chad Blakley, who shared the sequence of images with The Local.

The Northern Lights or Aurora Borealis are a natural phenomenon caused by solar winds clashing with the Earth's atmosphere, creating a green-tinged appearance in the sky.

The colourful displays can appear from the beginning of October to the end of March in large parts of northern Scandinavia, as long as the sky is clear.

“In addition, we have just entered the new solar cycle, which means that we should see more and more activity as we approach solar maximum,” said Blakley.

The solar cycle is the sun's approximately 11-year cycle during which solar storms build up and eventually settle back down. Scientists expect that solar activity will now increase and peak in 2025, according to Nasa.
