MINNEAPOLIS — The northern lights rise like glowing pillars and then unfurl to stretch across the night sky. They wave like a flag, shimmering green with purple at the fringes, below a tapestry of stars. Sometimes they transform nearly the whole sky into their dance floor, flitting north and south in hues from blue to yellow and even pink and red. The beauty is astounding; it’s almost surreal.
Or so I’ve been told.
I have never seen the celebrated, iconic aurora borealis streaming ribbons of color. Though I have lived in Minnesota most of my life and take several trips north each year, the vision I consider almost a birthright has eluded me. I expect that will change soon. Tired of friends marveling at their sighting and of being relegated myself to viewings via photographs, I made a plan to increase my odds that includes trips to points north and weather forecasts — on both the sun and the Earth.

Good thing I decided to get serious in my search this year. The aurora borealis — and its southern counterpart, the aurora australis — starts when the sun has a solar flare or coronal mass ejection and hurls charged particles across the heavens. Given the right trajectory, those particles can get trapped by Earth’s magnetic field and collide with gases in the upper atmosphere as they zoom toward the poles. It’s such energetic collisions that give the night sky its luminous glow. The sun has its own cycles, akin to our seasons, and is currently in the midst of heightened solar flare activity. Another such period won’t return for nine to 14 years.
Nonscientific translation: This is the year of aurora borealis. I hope.
Seeing the northern lights can be a tricky thing. Particle storms from solar flares take 48 hours to arrive at our humble place in the universe. There are some 90 million miles between the sun and the Earth, affording opportunities for the storms to lose energy or veer off course. Even if they stay on track, they can arrive during daylight hours, when the high-energy, high-altitude show carries on unseen by human eyes. Or a storm can arrive at night, only to have its otherworldly displays masked by worldly clouds.
Early detection of solar flares, though, is my ticket to the night sky show because it allows scientists to predict the occurrence of northern lights.
Travis Novitsky, a worker at Grand Portage State Park, just 500 feet south of the Canadian border, has been an avid northern lights viewer and photographer for 20 years. He follows spaceweather.com, a site that will also send “space weather alerts” to smartphones for $4.95. The Space Weather Prediction Center at www.swpc.noaa.gov offers forecasts for auroras and will send email alerts for free. Novitsky suggested I follow one of the sites, but warns that it is not an exact science.
“We had a promising forecast just a few days ago. Space weather forecasters were saying there was a 90 percent chance, but it never materialized — and we actually had clear skies,” he said. It was the case of an “empty cloud.” The sun had emitted a plasma, but it didn’t contain the stuff of colorful shows.
Novitsky, who has been known to hold all-night viewing parties when conditions are ripe, said that he always heads north of any town. Even the lights from a town as small as Grand Marais, Minn. — one of my favorite Up North perches — can wash out all but the brightest aurora display.
He situates himself on the south shore of a lake or an open meadow or any place with a wide-open view to the north.
