Aurora forecast: Northern Lights set to dazzle 20 US states — Here’s when and how to watch

A fresh Northern Lights forecast has raised hopes for skywatchers across the United States, with more than 20 states expected to witness the dazzling natural phenomenon this week. According to the National Oceanic and Atmospheric Administration (NOAA), favourable conditions could make the aurora visible as far south as parts of the Midwest, depending on weather and light conditions.

The latest aurora forecast suggests heightened geomagnetic activity, offering a rare chance for residents in lower-latitude regions to catch a glimpse of the shimmering lights.

Northern Lights Forecast: What the Data Shows

The National Oceanic and Atmospheric Administration has issued a Kp index of four for the current viewing window. This level indicates moderate geomagnetic activity, which experts say can produce auroras that are “quite pleasing to look at” under the right conditions.


The aurora forecast places the viewing line stretching as far south as southern Iowa by Wednesday, significantly expanding visibility beyond the usual northern states. However, the intensity is expected to fluctuate, with Tuesday’s chances slightly lower before improving again midweek.

Where the Aurora Borealis May Be Visible

The aurora borealis is most likely to be visible in northern regions, but this week’s forecast extends opportunities to a broader area. States within the visibility zone include Alaska, Washington, Idaho, Montana, North Dakota, South Dakota, Minnesota, Wisconsin, Michigan, New York, and parts of Pennsylvania and New England, as per a report by Forbes.

The highest chances remain concentrated in Alaska and the northernmost parts of the continental US, particularly Montana, North Dakota, and Minnesota. Observers located closer to the northern border are more likely to experience brighter and more vivid displays.

Best Time and Conditions for Viewing

Experts recommend heading outdoors between 10 p.m. and 2 a.m., when auroral activity is typically at its peak. A dark sky free from light pollution is essential for optimal viewing.

Clear weather conditions and minimal moonlight can significantly enhance visibility. Higher vantage points, such as hills or open landscapes, are also ideal for spotting the lights.

Tips to Photograph the Northern Lights

Capturing the Northern Lights requires some preparation. Photographers are advised to use a tripod to stabilise the camera and enable night mode or long-exposure settings.

Avoid using flash, as it can wash out the natural colours of the aurora. Instead, shooting with a low aperture and allowing more light into the lens can help produce clearer and more vibrant images.

Why Aurora Activity Is Increasing

Scientists attribute the recent surge in aurora forecast activity to the Sun’s ongoing 11-year solar cycle. The cycle reached a peak phase in late 2024 and is expected to continue influencing geomagnetic activity through 2026.

During this period, increased solar storms and charged particles interact with Earth’s magnetic field, creating the glowing patterns known as the aurora borealis.

Recent weekends have already seen similar activity, with multiple states reporting visible auroras during minor geomagnetic storms.

A Rare Opportunity for Skywatchers

While the Northern Lights is typically associated with polar regions, this week’s expanded aurora forecast provides a rare opportunity for millions of people in the US to witness the spectacle closer to home.

Experts caution, however, that visibility ultimately depends on local weather conditions and solar activity, both of which can change rapidly.
