Northern lights may be visible in these 18 US states tonight and over the weekend
## Chasing the Aurora: Northern Lights Could Dance Across 18 US States This Weekend!
The aurora borealis, also known as the Northern Lights, is one of nature's most breathtaking displays. For many, witnessing this celestial ballet is a bucket-list item. And this weekend, that dream might be closer to reality than you think! Thanks to a powerful solar storm, the aurora is predicted to be visible in a much wider swathe of the United States than usual, potentially reaching as far south as states not normally associated with aurora viewing.
So, where and when can you catch this spectacular show? Let's break it down:
The Trigger: A Powerful Geomagnetic Storm
The aurora borealis is caused by electrically charged particles from the sun colliding with atoms and molecules in the Earth's upper atmosphere. These collisions excite the atmospheric gases, causing them to emit light of various colors – most commonly green, but also red, pink, purple, and yellow.
These particles are often ejected from the sun during solar flares and coronal mass ejections (CMEs). A particularly strong CME is currently hurtling towards Earth, and NOAA's Space Weather Prediction Center (SWPC) has issued a G4 (Severe) Geomagnetic Storm Watch. This means a significant disturbance in the Earth's magnetic field is expected, pushing the aurora further south than its usual polar latitudes.
The 18 States in the Potential Viewing Zone:
While predicting the exact location and intensity of the aurora is notoriously difficult, forecasters believe these 18 states have a chance of witnessing the Northern Lights tonight (date) and over the weekend:
Northern Tier States:
Alaska: (Of course! Always a prime viewing location)
Washington:
Idaho:
Montana:
North Dakota:
South Dakota:
Minnesota:
Wisconsin:
Michigan:
Maine:
Further South, Depending on Geomagnetic Activity:
Oregon:
Wyoming:
Nebraska:
Iowa:
Illinois:
Indiana:
Pennsylvania:
New York:
Important Note: The further south you are, the weaker the aurora is likely to be. Those in the northern tier states have a much higher chance of a vibrant display. Even in the southern states, a strong geomagnetic storm is needed for visibility, and the aurora may appear as a faint glow or shimmering on the northern horizon.
Tips for Maximizing Your Aurora Viewing Chances:
1. Find a Dark Location: This is crucial. Light pollution from cities and towns will significantly diminish your ability to see the aurora. Escape to rural areas away from artificial light. Parks, open fields, and even high-elevation areas are ideal.
2. Check the Space Weather Forecast: The SWPC ([https://www.swpc.noaa.gov/](https://www.swpc.noaa.gov/)) is your best resource. Pay attention to:
Kp Index: This measures the strength of geomagnetic activity on a scale of 0-9. A higher Kp index indicates a stronger aurora and greater visibility at lower latitudes. Look for a Kp index of 7 or higher for a good chance of seeing the aurora in the southern states listed.
Ovulation (OVATION) Aurora Forecast: This model provides a real-time prediction of aurora location based on current geomagnetic conditions. It can help you estimate the likelihood of seeing the aurora from your specific location.
3. Look North: The aurora typically appears on the northern horizon. Use a compass app on your phone if you're unsure of your orientation.
4. Be Patient: Aurora displays can be sporadic. You might see a brilliant show one minute and nothing the next. Be prepared to spend a few hours observing the sky.
5. Time Your Viewing: The best time to view the aurora is usually between 10 PM and 2 AM local time, although activity can occur at any time of night.
6. Use Your Camera: Even if the aurora appears faint to the naked eye, your camera might be able to capture it more clearly. Use a long exposure (several seconds) and a wide aperture (low f-number like f/2.8 or lower) to gather as much light as possible. A tripod is essential for steady shots.
7. Download Aurora Alert Apps: Many apps are available that track space weather and send alerts when aurora activity is high. Some popular options include Aurora Forecast, My Aurora Forecast, and SpaceWeatherLive.
8. Cloud Cover is the Enemy: Check the weather forecast! Clear skies are essential for aurora viewing.
What if You're Too Far South or the Aurora is Weak?
Even if you're not in one of the 18 states or the aurora is not as strong as predicted, you can still experience the wonder of the Northern Lights. Here are a few alternative options:
Livestream the Aurora: Many live streams capture the aurora from locations in the Arctic Circle. Search for "aurora borealis live stream" on YouTube or other video platforms.
Explore Aurora Photography: Admire stunning images of the aurora taken by talented photographers around the world. This can be a great source of inspiration and a reminder of the beauty of our planet.
Plan a Future Trip: If seeing the aurora is a lifelong dream, consider planning a trip to a prime viewing location like Iceland, Norway, or Alaska during the winter months.
Don't Miss This Opportunity!
This weekend presents a unique opportunity to witness the magic of the Northern Lights from a wider area than usual. While there are no guarantees, following the tips above can significantly increase your chances of catching this spectacular celestial display. Good luck, and happy aurora hunting!
