The Northern Lights, a natural phenomenon painting the sky with shades of green, pink, and purple, may be visible on Monday night, August 18, 2025, across 16 U.S. states, according to the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center. The celestial display, driven by a G1-level geomagnetic storm, is expected between 11 p.m. and 5 a.m. local time in northern states like Alaska, Montana, and Maine. Visibility will be enhanced by dark skies, as the moon rises in the early morning hours, creating ideal viewing conditions.
The chance to see the Northern Lights stems from a solar wind stream originating from a coronal hole on the Sun, interacting with Earth’s magnetic field. This event marks the start of the aurora season in the Northern Hemisphere, which intensifies between August and September.
For those eager to witness the phenomenon, NOAA advises seeking locations with low light pollution and an unobstructed northern horizon.
- States with viewing potential: Alaska, Washington, Idaho, Montana, Wyoming, North Dakota, South Dakota, Minnesota, Wisconsin, Iowa, northern Illinois, Michigan, New York, Vermont, New Hampshire, and Maine.
- Best time: Between 11 p.m. and 5 a.m., with peak activity from midnight to 2 a.m.
- Ideal conditions: Clear skies and areas away from urban lights.
What causes the Northern Lights spectacle
The Northern Lights occur when charged particles from the Sun, carried by the solar wind, collide with atmospheric gases. This interaction causes atoms in the atmosphere to emit light, creating the iconic colorful curtains in the sky. On August 18, NOAA forecastspun intended

collide with atmospheric gases. This interaction causes atoms in the atmosphere to emit light, creating the iconic colorful curtains in the sky. On August 18, NOAA predicts a G1-level geomagnetic storm, classified as minor on a scale up to G5. Though a low-intensity event, the strength of the solar wind from a coronal hole may produce auroras visible at lower latitudes than usual, reaching states like Iowa and Illinois.
The Kp index, which measures geomagnetic activity on a scale of 0 to 9, is expected to reach level 5 on Monday night. This indicates a moderate aurora, bright enough to be seen with the naked eye under favorable conditions. Forecasts also suggest possible geomagnetic storms on Tuesday, August 19, due to a coronal mass ejection (CME) that may indirectly impact Earth.
How to enjoy the Northern Lights in the US
To maximize chances of seeing the Northern Lights, choosing the right location is key, as city light pollution can obscure the phenomenon. Rural areas, mountains, or national parks with unobstructed northern views are ideal.
- Recommended locations: National parks like Glacier (Montana), Acadia (Maine), or Denali (Alaska).
- Useful equipment: Smartphones with night mode or cameras with long exposure to capture vibrant colors.
- Observation tips: Arrive early and stay alert, as auroras may appear in waves.
- Helpful apps: My Aurora Forecast and Space Weather Live for real-time predictions.
Aurora visibility depends on factors like weather and solar wind intensity, so checking NOAA updates or specialized apps is advised.
Why 2025 is a special year for auroras
The year 2025 coincides with the peak of the 11-year solar cycle, known as solar maximum, when the Sun’s magnetic activity is at its height. This increased solar activity leads to more geomagnetic storms, boosting aurora occurrences. Although the peak likely occurred in late 2024, the coming years, especially 2025 and 2026, promise frequent displays.
Last year, notable solar events, like the X9.0 flare in October 2024, produced auroras visible as far south as Florida and Texas. This week’s forecast suggests less intense conditions but still sufficient for a spectacle in northern areas.
- Factors amplifying auroras: Increased sunspots and coronal mass ejections.
- Current solar cycle: The 25th solar cycle, peaking in 2024 with a gradual decline until 2026.
- Visibility impact: Auroras may be seen at lower latitudes during stronger storms.
Tips for photographing the Northern Lights
Capturing the Northern Lights in photos is a way to preserve the moment, and modern technology makes it accessible even for amateurs. Smartphones with night mode can capture vibrant colors, often more vivid in images than to the naked eye. For best results, use a tripod to stabilize the camera and adjust exposure settings.
Professional photographers recommend wide-angle lenses and low shutter speeds to capture the lights’ movement. Patience is key, as auroras can vary in intensity throughout the night.
- Smartphone settings: Enable night mode and use a tripod.
- Professional cameras: Use high ISO (800-3200) and 5-15 second exposures.
- Strategic locations: Avoid areas with artificial light for better results.
- Support apps: Apps like PhotoPills aid in planning photography sessions.
Regions with the highest likelihood of sightings
States with the best chances of seeing the Northern Lights tonight include Alaska, which leads due to its proximity to the Arctic Circle, followed by Montana, North Dakota, and Minnesota. More southern regions, like Iowa and northern Illinois, are on the visibility threshold, where the aurora may appear only on the northern horizon.
NOAA uses the OVATION model to predict aurora location and intensity based on geomagnetic activity. The “viewline” indicates the southernmost areas where the phenomenon may be visible. On Monday, this line covers 16 states, with potential expansion if the geomagnetic storm exceeds predictions.
- High-probability states: Alaska, Montana, North Dakota, Minnesota, Wisconsin, Michigan, Maine.
- Moderate visibility states: Washington, Idaho, South Dakota, Vermont, New Hampshire.
- Threshold states: Wyoming, Iowa, New York, northern Illinois.
Preparing for the aurora season
The aurora season in the Northern Hemisphere, from August to April, features longer, darker nights ideal for viewing. NOAA’s forecast suggests elevated solar activity in the coming months, offering more aurora sighting opportunities.
For enthusiasts, platforms like Aurorasaurus, which collects real-time sighting reports, are valuable tools. Choosing locations with clear skies and low light pollution significantly boosts success rates.
- Ideal months for auroras: August to April, peaking between September and March.
- Monitoring tools: Platforms like Aurorasaurus and NOAA maps.
- Popular destinations: National parks and rural areas in the northern US.
The Northern Lights are an unpredictable phenomenon, but current conditions favor a memorable spectacle for residents of the listed states. The combination of a moderate geomagnetic storm and dark skies creates a unique opportunity to witness one of nature’s most fascinating events.
