The Northern Lights Will Be Visible This Week — How to Watch the Stunning Spectacle
If you're a fellow stargazer and skywatcher, you're in luck!With March's action-packed skies and the spring season approaching, it's shaping up to be one of the best months of the year for catching a glimpse of the northern lights. Northern lights, or Aurora Borealis, occur when solar activity — such as solar flares or coronal mass ejections — causes magnetic storms. These storms trigger interactions between the Earth's magnetic field and charged particles from the sun, resulting in the stunning colors that light up the sky. According to NASA solar physicist David Hathaway's 75-year study reveals that March has more geomagnetically active days than any other month. With six days of high geomagnetic activity, compared to just three in December, March offers a prime window for spotting the northern lights. Becoming an aurora chaser this spring wouldn't be unusual, thanks to heightened solar activity as we reach solar maximum — the peak of the sun's approximately 11-year solar cycle. Here's everything you need to know about this month's stellar skies.

You'll also want to wait for clear skies; too many clouds can block your view of the colorful display on any given is key, and allowing extra time in your "aurora season" itinerary for unpredictable weather doesn't hurt.

Look for the Northern Lights Tonight: Aurora Borealis Has a Season, and It Just Started
Aurora borealis is one of the coolest astronomical events that we can see with the naked eye. It makes the sky glow beautiful colors, and auroras are just random enough to be exciting occurrences. But they may not be as random as we all think: Historical data suggests that aurora borealis has seasons where they are more likely to occur than other times of the year. The spring equinox is one of those times, and it's right around the corner. Read more: Spring Equinox Is Almost Here: Have You Heard the Egg-Balancing Myth? The idea that aurora borealis has "seasons" comes from data compiled by NASA astrophysicist, Dr. David Hathaway. According to the data, the northern lights are more likely to show up in March, April, September, and October. Those are the months closest to the spring and autumn equinoxes -- the time of year when the sun crosses the equator and delivers almost equal amounts of daylight to the entire planet. Hathaway's data is the latest, but it's not the first. Per Earth Sky, Aloysius Cortie, an English Jesuit astronomer, published research on the link between equinoxes and auroras in 1912. Later, Sydney Chapman and Julius Bartels included the idea of a twice-yearly aurora borealis season in their book Geomagnetism, which was the de facto textbook on the topic for decades.

The key to the whole thing seems to be how equinoxes work. During the winter and summer months, half of the Earth is tilted away from the sun, therefore making aurora borealis less likely (unless the geomagnetic storm is particularly strong). "The equinoxes are the transition points between which hemisphere is tilted toward the Sun," Shannon Schmoll, director of the Abrams Planetarium, told CNET in an email. "At this point, the Earth's magnetic field is at a more favorable angle, closer to perpendicular, that allows easier interaction of the charged solar particles with the Earth's magnetic field and atmosphere." Read more: Why Is The Aurora Borealis More Frequent All of a Sudden? According to Dr. Schmoll, the Earth's magnetic field has a north and south pole, just like any magnet. The sun does as well. Dr. Schmoll says that science is still figuring out the specifics, but in short, the poles of the sun and Earth line up better during the equinox, which is conducive to more frequent auroras. "The relative positions of all the magnetic field lines around this time make it easier for Earth to interact with the sun's charged solar wind, resulting in aurora," Schmoll says. The equinox effect -- also known as the Russell-McPherron effect -- is also entirely separate from the 11-year solar cycle that the sun runs through. Currently, the sun is at its maximum for this cycle, which increases the odds of aurora borealis showing up even more. The sun's increased activity and the equinox effect have already been observed recently. Late in 2024, aurora borealis lit up the night sky for much of September and October, with some being visible way further into the US than is typical. 'Tis the season, as they say, and aurora borealis is already making its presence known. Per the Space Weather Prediction Center, an aurora is happening Tuesday, March 4, for one night only. It won't reach down as far as Texas like some of the more epic auroras did last year, but it should be a pretty good display for folks in the northern US. The aurora is predicted to reach as far south as Iowa, with people in Montana, North Dakota, and Minnesota getting the best views. It'll also be partially visible in Wyoming, South Dakota, Wisconsin, Maine, Michigan and parts of New York, New Hampshire and Vermont.
