Northern lights return to Vancouver
The aurora borealis are not normally spotted so far south
The northern lights were spotted over Vancouver's North Shore Mountains on Sunday by photographer Rick Etkin, who posted a video on Twitter.
The northern lights are not normally visible this far south, but in June they were also spotted from many southerly locations around the world, because of the unusually strong solar storm on the surface of the sun.
Also known as aurora borealis, they are created by solar flares on the sun's surface that create gusts of solar winds that pass through the Earth's atmosphere causing particles to emit the brilliant colours.
