Skywatchers across parts of the northern United States may have a rare
opportunity to witness one of nature's most spectacular light displays tonight. A
stream of fast-moving solar wind is expected to reach Earth, creating conditions
that could make the Northern Lights, also known as the Aurora Borealis, visible
across several states near the Canadian border.
While this is not expected to become a powerful geomagnetic storm, experts say
the event could still generate beautiful green and purple curtains of light under
favorable weather and sky conditions. If you're planning to chase the aurora, now
is the perfect time to prepare your camera, check the weather forecast, and head to
a dark location far from city lights.
Whether you're an experienced photographer or simply hoping to witness the
aurora for the first time, here's everything you need to know.
Why Are the Northern Lights Appearing Tonight?
The expected aurora display is being triggered by a high-speed stream of solar
wind flowing from a large coronal hole on the sun.
Unlike a Coronal Mass Ejection (CME)—which ejects billions of tons of plasma into
space and often creates intense geomagnetic storms—this event originates from
an opening in the sun's magnetic field. Through these openings, charged solar
particles escape into space at extremely high speeds.
When these particles collide with Earth's magnetic field, they energize oxygen and
nitrogen molecules high in the atmosphere. As these gases release energy, they
produce the glowing green, red, purple, and pink lights that make the aurora
borealis so famous.
Although coronal-hole events are usually weaker than CME-driven storms, they
frequently produce impressive auroras across northern regions.
Latest Space Weather Forecast
According to space weather forecasters, geomagnetic activity is expected to
strengthen late Tuesday night and continue into Wednesday morning.
Scientists are predicting a G1 Minor Geomagnetic Storm, which is considered the
lowest level on NOAA's five-step geomagnetic storm scale.
Even though this is a relatively mild event, it may still push the aurora farther south
than normal, allowing millions of Americans an opportunity to see the display.
Forecast timing remains somewhat uncertain because solar wind streams from
coronal holes can arrive earlier or later than expected.
For that reason, skywatchers should continue monitoring real-time aurora
forecasts throughout the evening.
What Is a G1 Geomagnetic Storm?
A G1 geomagnetic storm is classified as a minor space weather event.
These storms usually have little impact on everyday life, although they can
occasionally cause:
Minor fluctuations in satellite operations
Small power grid disturbances
Slight changes in radio communications
Enhanced aurora visibility
The biggest benefit for the public is the possibility of seeing the Northern Lights
much farther south than usual.
10 U.S. States That Could See the Aurora Tonight
If conditions remain favorable, residents in the following states have the highest
chance of spotting the aurora:
Washington
Idaho
Montana
North Dakota
Minnesota
Wisconsin
Michigan
Maine
Vermont
New Hampshire
People living in northern portions of these states, especially near the Canadian
border, will enjoy the best viewing opportunities.
In rare cases, stronger geomagnetic activity may briefly allow the aurora to be seen
even farther south.
Best Time to Watch
The most favorable viewing period generally begins after full darkness and
continues through the early morning hours.
Experts recommend looking between:
10:00 PM
2:00 AM local time
The darkest hours usually provide the highest contrast between the sky and the
aurora.
Because July nights are relatively short, viewers will have a smaller observation
window compared to autumn or winter.
Weather Could Make or Break the Show
Even a strong aurora cannot be seen through thick clouds.
Before traveling, check:
Cloud cover forecasts
Local weather radar
Moon brightness
Air quality
Visibility reports
Clear skies remain the single most important factor for successful aurora viewing.
Escape City Lights
Light pollution dramatically reduces visibility.
For the best experience:
Drive outside urban areas.
Visit state parks.
Choose rural farmland.
Find lakes or mountain viewpoints.
Stay away from highways and commercial lighting.
Dark Sky Parks offer some of the finest viewing conditions and are popular
destinations for astrophotographers.
Be Patient
Many first-time viewers expect the Northern Lights to appear immediately.
In reality, auroras often begin as a faint gray glow before suddenly transforming
into bright moving curtains across the sky.
Activity may increase and decrease several times during the night.
Experienced aurora hunters often wait several hours before witnessing the
strongest displays.
Patience is one of the most valuable tools you can bring.
Check Live Aurora Forecasts
Aurora conditions change rapidly.
Several forecasting services provide updates every few minutes based on solar
wind measurements.
These forecasts track:
Solar wind speed
Magnetic field orientation
Geomagnetic activity
Aurora probability
Cloud forecasts
Monitoring live updates can significantly improve your chances of seeing the lights.
Can You See the Aurora With Your Eyes?
Yes—but the experience depends on storm intensity.
During weaker geomagnetic storms:
The aurora may appear pale green or gray.
Colors may seem faint.
Movement can be subtle.
During stronger bursts:
Bright green curtains become obvious.
Purple and red colors may appear.
Waves ripple across the sky.
Vertical light pillars become visible.
Human eyes do not always detect color as well in darkness, so cameras often reveal
a more vibrant display than what you see naturally.
How to Photograph the Northern Lights With a Smartphone
Modern smartphones have become surprisingly effective at photographing auroras.
To capture the best images:
Use Night Mode
Most recent smartphones automatically detect low-light conditions and activate
Night Mode.
Keep the Phone Steady
Even slight movement creates blurry images.
Use:
A tripod
A rock
A fence
A backpack
Anything stable helps.
Enable Long Exposure
Phones with Pro Mode allow manual exposure settings.
Longer exposures collect more light and reveal details invisible to the naked eye.
Turn Off Flash
Flash has no effect on the aurora and only wastes battery power.
Focus on the Sky
Tap the brightest part of the aurora before taking your photo.
Manual focus usually produces sharper images.
Shoot Multiple Photos
Auroras constantly change shape.
Taking many images increases your chances of capturing an unforgettable
moment.
DSLR Camera Tips
If you're using a DSLR or mirrorless camera:
Use a wide-angle lens.
Set ISO between 800–3200.
Use a tripod.
Shoot in RAW.
Try exposure times between 5–15 seconds.
Use manual focus.
These settings often produce professional-quality aurora photographs.
Why Summer Auroras Are Harder to See
Although auroras occur year-round, summer presents unique challenges.
Northern regions experience:
Short nights
Brighter twilight
Increased moonlight
Lower sky contrast
These conditions make weaker auroras harder to detect.
Nevertheless, strong solar activity can still produce breathtaking displays even
during July.
Why This Aurora Matters
Solar activity has remained elevated as the Sun approaches the peak of its current
solar cycle.
Scientists expect more frequent geomagnetic storms during this period, increasing
opportunities to witness spectacular aurora displays across North America,
Europe, and parts of Asia.
Each event also provides researchers valuable information about how Earth's
magnetic field interacts with space weather.
Travel Opportunities for Aurora Enthusiasts
For travelers interested in astronomy tourism, aurora season continues to be one
of the fastest-growing adventure travel experiences.
Popular destinations include:
Alaska
Northern Canada
Iceland
Norway
Finland
Sweden
Many visitors combine aurora viewing with luxury travel packages, winter resorts,
wildlife photography, and national park adventures, making these trips especially
attractive for premium travel audiences.
Tonight's expected G1 geomagnetic storm may not be the strongest space weather
event of the year, but it still offers an exciting opportunity for millions of people
across the northern United States to witness one of nature's greatest spectacles.
If skies remain clear and the solar wind aligns favorably with Earth's magnetic field,
residents in Washington, Idaho, Montana, North Dakota, Minnesota, Wisconsin,
Michigan, Maine, Vermont, and New Hampshire could enjoy a memorable display
of the Northern Lights.
Charge your phone, prepare your camera, travel to a dark location, and keep an eye
on the latest aurora forecasts. Even a minor geomagnetic storm can produce an
unforgettable night beneath shimmering green skies.
