Aurora Forecast for Tonight: Northern Lights Expected Across the US
Tonight, the northern lights, or auroras, could light up the skies across parts of the US. Following a recent intense geomagnetic storm, moderate geomagnetic activity is forecasted to continue, potentially offering a dazzling display of the aurora borealis in northern states.
What’s Happening? Understanding the Aurora Forecast
Geomagnetic storms are caused when charged particles from the sun interact with Earth’s magnetic field. Yesterday’s severe G4-class storm sent a massive cloud of magnetically charged solar plasma, known as a coronal mass ejection (CME), hurtling towards our planet. This powerful storm triggered stunning auroras worldwide, from Australia to the UK and Canada.
Today, we’re expecting a G2-class geomagnetic storm. While less intense than yesterday’s event, a G2 storm can still bring the northern lights into view across the northern US.
Where Can You See the Northern Lights Tonight?
According to the NOAA Space Weather Prediction Center (SWPC), tonight’s auroras might be visible in several northern and upper Midwest states. The likely areas include:
- Washington
- Montana
- Idaho
- North Dakota
- South Dakota
- Minnesota
- Wisconsin
- Michigan
- New York
- Maine
If you’re in these regions, keep your eyes peeled for a spectacular light show!
How Do Geomagnetic Storms Create Auroras?
Geomagnetic storms occur when a CME impacts Earth’s magnetic field. The charged particles from the CME travel along the magnetic field lines into Earth’s upper atmosphere. Here’s how it works:
- Particles from the CME slam into Earth’s atmosphere.
- Energy from these collisions excites atmospheric particles, causing them to glow.
- Different gases produce different colours: Red from high-altitude oxygen, green from lower-altitude oxygen, and purple or violet from nitrogen.
Professor Martin Connors from Athabasca University explains that this process is what creates the stunning auroral displays we see in the night sky.
Understanding the G-Scale: What Do the Ratings Mean?
Geomagnetic storms are rated on the G-scale, which ranges from G1 to G5:
- G1 (Minor): Minor disturbances with minimal effects.
- G2 (Moderate): Can cause minor voltage issues and affect satellite operations.
- G3 (Strong): May impact power grids and increase satellite drag.
- G4 (Severe): Can cause widespread voltage problems and satellite issues.
- G5 (Extreme): The most severe, rare and can cause major disruptions to power grids and satellite operations.
Yesterday’s G4 storm was particularly intense, but tonight’s G2 storm is expected to be milder. Still, it’s strong enough to potentially offer a spectacular aurora display.
Why Should You Watch? The Beauty of the Aurora Borealis
The northern lights are one of nature’s most breathtaking phenomena. Seeing them is not only a rare and beautiful experience but also a fantastic opportunity to witness the power of solar activity.
Whether you’re a seasoned aurora chaser or a curious onlooker, tonight’s display promises to be a memorable sight. Grab a camera and get outside—these lights won’t be around forever!
How to Maximise Your Viewing Experience
To get the best view of the aurora borealis, follow these tips:
- Find a Dark Spot: Get away from city lights for the best visibility.
- Check the Weather: Clear skies are essential for seeing the auroras.
- Bring a Camera: Capture the beauty of the aurora with a camera equipped for low-light photography.
- Be Patient: Auroras can be unpredictable. Be prepared to wait for the display to begin.
Conclusion
Tonight’s aurora forecast brings an exciting opportunity to witness the northern lights across parts of the US. Although the geomagnetic activity is forecasted to be moderate, it should still provide a stunning light show for those in the northern states.
Keep an eye on the skies, prepare for a night of celestial wonder, and enjoy one of nature’s most spectacular phenomena.
