A vivid aurora curtain stretches across the night sky

There’s a reason to look up tonight. Right now, the alignment of the Sun and Earth is working a little magic, and around the spring equinox, the chances of seeing the northern lights at lower latitudes than usual are significantly higher. The latest models from weather agencies indicate a moderate to strong geomagnetic storm is expected from March 20 to 21. That means, from Scandinavia and Canada to—if you’re lucky—even your own neighbourhood, that ethereal celestial curtain might just make an appearance.

Why Are Auroras Special Around the Spring Equinox?

Long-time skywatchers have a saying: “The equinoxes are prime time for auroras.” And there’s solid science behind it. As someone who’s followed the relationship between Earth’s magnetosphere and solar wind for years, I can tell you it’s a phenomenon known as the Russell-McPherron effect. During the spring and autumn equinoxes, the orientation of the solar wind relative to Earth’s rotational axis becomes nearly perpendicular. This makes it easier for energy to build up in our magnetosphere, essentially allowing particles from the Sun to be “funnelled” into Earth’s magnetic field with far greater efficiency than usual. That’s the mechanism that can supercharge the aurora borealis.

This year, the conditions for the spring equinox are aligning almost perfectly. The effects of a coronal hole that was recently active on the Sun’s surface are reaching Earth right at this moment. Forecasts for geomagnetic storm activity have been upgraded from “G2 (Moderate)” to “G3 (Strong),” and experts are buzzing with excitement, calling this “the most promising night in years.”

Prime Viewing Time: Two Consecutive Nights—Tonight and Tomorrow

The main event is expected to unfold from sunset tonight, Friday, March 20, 2026, into the late-night hours. If forecasts hold, activity could continue during the same timeframe on Saturday, March 21. The peak of geomagnetic disturbance is predicted between 11:00 PM and 2:00 AM local time.

Of course, the biggest obstacles for aurora viewing are clouds and light pollution. Fortunately, a high-pressure system is expected to cover much of the region from the Sea of Japan side to the Pacific side this weekend, offering clear skies across wide areas. In places like Hokkaido, the Sea of Japan coast of Tohoku, or higher-elevation spots, there’s a strong chance you’ll see faint pink or green ribbons with the naked eye. Even if you usually think of the northern lights as something you only see on TV, tonight it’s worth taking a moment to scan the northern horizon.

If you want to maximize your chances tonight, keep these three essentials in mind.

  • Find a dark spot with a clear northern view: An unlit coastline or a parking lot in the highlands is ideal.
  • Put your camera on a tripod and let it work: Even if the aurora is faint to the naked eye, a long exposure can reveal a world of colour. With your smartphone, try using night mode on a steady surface—you might be surprised by what you capture.
  • Dress for deep winter: Late March nights can be deceivingly cold. A thermos of hot coffee and a hand warmer are essentials.

The Romance Behind the Name “Aurora”

In Nordic countries and Russia, this natural phenomenon is called “Aurora,” a name that not only sounds beautiful but carries the meaning of “dawn.” It comes from the Roman goddess of the dawn, perfectly symbolizing that moment when darkness gives way to light. If you catch a faint glow in the northern sky tonight, it’s more than just a light show—it could be the universe’s own “dawn announcement.”

It reminds me of a night spent waiting in an Icelandic fjord, enduring minus 15-degree cold. Just as everyone was about to give up and head back to the car, the entire sky began to ripple like a silk curtain. That kind of awe is more profound than any technology can capture. Data and forecasts are helpful, but in the end, it comes down to your own eyes and a little luck. May the goddess of the dawn dance across your sky tonight.

So, charge up your camera batteries, fill your thermos with coffee, and get ready. It’s almost time to begin.
