Northern Lights: Coming to a Sky Near You?

The massive flare that erupted from the sun on Tuesday could bring beautiful displays of the Northern Lights as far south as Colorado late on Thursday night and early Friday morning.

It was associated with a huge eruption of material called a coronal mass ejection. Now, that material is racing toward Earth and is expected to trigger a strong geomagnetic storm — a disturbance to Earth’s protective magnetic bubble called the magnetosphere. It’s that kind of disturbance that triggers the Northern Lights.

The University of Alaska’s Geophysical Institute predicts that auroral activity will be high on Thursday:

Weather permitting, highly active auroral displays will be visible overhead from Inuvik, Yellowknife, Rankin and Igaluit to Juneau, Edmonton, Winnipeg, Thunder Bay and Sept-Iles, and visible low on the horizon from Seattle, Des Moines, Chicago, Cleveland, Boston, and Halifax.

The Denver Post is reporting that displays of the aurora could even reach where I live near Boulder, Colorado. “This is very rare, especially for as far south as Denver and Boulder,” Joe Kunches, a forecaster with the federal Space Weather Prediction Center, told the Post.

There are no guarantees, of course. Clouds could obscure the view, city lights could wash it out, the solar material could arrive earlier or later than forecast, affecting visibility, etc. For the latest updates on what might happen, check the Space Weather Prediction Center here.

Happy viewing!

    Aurorae are the most visible effect of the Sun’s activity on the Earth’s
    atmosphere, and are evidence that the Sun and Earth are connected by
    more than just sunlight. The occurrence and frequency of the Northern
    Lights depends on the activity of the Sun, which has an eleven year
    cycle. The displays are linked with the solar wind, a continuous flow of
    electrically charged particles from the Sun. These particles travel
    through space and if they reach the Earth’s magnetic field they travel
    towards the magnetic poles (the North and South Poles) colliding with
    oxygen and nitrogen molecules along the way. When a large number of
    these fast-moving collisions occur, it produces enough light for the eye
    to detect, and appear as coloured dancing streaks or arcs of light
    across the sky.

    How does this rate against the Carrington event?

    Where I live in Montana, we only get the Northern Lights occasionally. I will be peering northward–if the clouds allow–tonight!

      Where I live in New Mexico, we never get the Northern lights. Enjoy the fact that you get to see them at all. I guess we do get lots of extremely nice sunsets and sunrises. You probably get those too though…
