What Makes The Northern Lights?


By By Steve Pool

SEATTLE - The Northern Lights are caused when the sun gives off electrically-charged particles from solar flares. The Earth's magnetic poles act like, well, a magnet to draw those particles to the polar regions. When the particles interact with the atmosphere, the give off the beautiful ribbons of purple, blue, red and green.

They're most common around the Arctic Circle, but during particularly strong solar flares, they can be seen as far south as Arizona.

Solar flares are supposed to increase over the next few months, so keep an eye to the northern sky on clear nights and maybe you'll catch them.

My lil' man Milo is an eleven year old Siamese mix that loves to watch the game with his mama (me!) I bought this t-shirt for my niece, but thought maybe he would let me take a few pics first - no problem! Modeling comes natural to my lil love bug.

This collection was taken with our Nikon D7100. On a round trip from the Bainbridge Island to Seattle. The weather was perfect to capture Mount Rainier while the Bremerton Ferry passed by. If you look closely you can see a lenticular cloud hovering above.
