A surge of geomagnetic activity could make the aurora borealis, or Northern Lights, visible across a wide swath of the United States, potentially reaching as far south as states like Pennsylvania, Iowa, and Oregon on June 1. A strong solar flare erupted from the sun, sending a coronal mass ejection (CME) towards Earth, increasing the likelihood of witnessing this spectacular celestial phenomenon in areas where it is rarely seen.
Northern Lights May Dance Across 24 States Tonight
The Northern Lights, typically confined to higher latitudes, may grace the skies of approximately 24 states tonight, June 1, due to an anticipated surge in geomagnetic activity. A recent solar flare has propelled a coronal mass ejection (CME) toward Earth, creating conditions ripe for the aurora borealis to be visible much further south than usual.
According to space weather forecasts, the aurora could potentially be seen in states including Washington, Idaho, Montana, Wyoming, North Dakota, South Dakota, Minnesota, Wisconsin, Michigan, New York, Vermont, New Hampshire, Maine, and potentially even further south into states like Pennsylvania, Iowa, and Oregon. The exact visibility will depend on the strength of the geomagnetic storm and local weather conditions, particularly clear skies and minimal light pollution.
“When the particles from a CME collide with the Earth’s magnetosphere, they can cause geomagnetic storms,” explained space weather experts. “These storms compress the magnetosphere, accelerating charged particles down into the atmosphere, primarily near the poles. These particles then collide with atoms and molecules in the upper atmosphere, exciting them and causing them to emit light – the aurora.”
Observers in the predicted viewing areas are advised to seek out dark locations away from city lights for the best chance to witness the aurora. The optimal viewing time is generally between 10 PM and 2 AM local time, but the lights can appear at any time during the night if the geomagnetic activity is strong enough.
Understanding the Science Behind the Aurora
The aurora borealis, also known as the Northern Lights, is a natural light display in the sky, predominantly seen in the high-latitude (Arctic and Antarctic) regions. Auroras are produced when the magnetosphere is sufficiently disturbed by the solar wind that the trajectories of charged particles in both solar wind and magnetospheric plasma, mainly in the form of electrons and protons, precipitate them from space into the upper atmosphere (thermosphere/exosphere).
The resulting ionization and excitation of atmospheric constituents emit light of varying color and complexity. The color of the aurora depends on the type of gas molecules that are excited by the charged particles. Green is the most common color, produced by oxygen molecules at lower altitudes. Red auroras are produced by oxygen at higher altitudes, while blue and purple auroras are produced by nitrogen.
Solar flares and coronal mass ejections are the primary drivers of geomagnetic storms that lead to auroral displays. Solar flares are sudden releases of energy from the sun’s surface, while coronal mass ejections are large expulsions of plasma and magnetic field from the sun’s corona. When these events reach Earth, they interact with the Earth’s magnetosphere, causing geomagnetic disturbances.
The strength of a geomagnetic storm is measured using the Kp index, which ranges from 0 to 9. A Kp index of 5 or higher indicates a geomagnetic storm, and the higher the Kp index, the stronger the storm and the further south the aurora can be seen. The current forecast suggests a Kp index that could reach levels high enough to make the aurora visible in the aforementioned states.

Detailed Explanation of Coronal Mass Ejections (CMEs)
Coronal Mass Ejections (CMEs) are one of the most significant drivers of space weather and the aurora borealis. Understanding their nature and behavior is crucial for comprehending the likelihood and intensity of auroral displays.
A CME is a massive expulsion of plasma and magnetic field from the Sun’s corona, the outermost layer of the Sun’s atmosphere. These ejections can contain billions of tons of matter and can travel at speeds ranging from a few hundred to several thousand kilometers per second.
Formation and Eruption:
CMEs are often associated with other forms of solar activity, such as solar flares and prominences. The exact mechanisms that trigger CMEs are still being researched, but it is believed that they are caused by the build-up and release of magnetic energy in the Sun’s corona.
The process typically begins with the twisting and tangling of magnetic field lines in the corona. As these field lines become more complex, they store increasing amounts of energy. Eventually, the magnetic field becomes unstable, and a rapid reconnection event occurs, releasing the stored energy and propelling the plasma and magnetic field outward into space.
Propagation and Interaction with Earth:
Once a CME is launched from the Sun, it travels through interplanetary space. The journey to Earth can take anywhere from one to several days, depending on the speed of the CME. As the CME propagates, it interacts with the solar wind, a continuous stream of charged particles flowing from the Sun.
When a CME reaches Earth, it interacts with the Earth’s magnetosphere, the protective magnetic bubble that surrounds our planet. The interaction can cause a variety of effects, including geomagnetic storms, auroras, and disruptions to radio communications and GPS navigation.
Geomagnetic Storms:
A geomagnetic storm is a temporary disturbance of the Earth’s magnetosphere caused by the solar wind. CMEs are one of the primary drivers of geomagnetic storms. When a CME impacts the magnetosphere, it can compress the magnetic field, accelerate charged particles, and induce currents in the Earth’s atmosphere and surface.
These effects can lead to a variety of impacts, including:
- Auroras: As described earlier, geomagnetic storms can cause the aurora borealis and aurora australis to become more visible and extend to lower latitudes.
- Radio Communication Disruptions: Geomagnetic storms can disrupt radio communications, particularly high-frequency (HF) radio used by aviation, maritime, and amateur radio operators.
- GPS Errors: Geomagnetic storms can cause errors in GPS positioning, which can affect navigation and surveying.
- Power Grid Disruptions: Strong geomagnetic storms can induce currents in power grids, which can overload transformers and cause blackouts.
- Satellite Damage: Geomagnetic storms can damage satellites, which can affect communications, navigation, and weather forecasting.
Forecasting CMEs:
Forecasting CMEs is a challenging but important task. Scientists use a variety of techniques to monitor the Sun and predict when CMEs are likely to occur. These techniques include:
- Solar Observations: Scientists use telescopes and other instruments to observe the Sun’s surface and corona. These observations can reveal features such as sunspots, flares, and prominences, which are often associated with CMEs.
- Space-Based Instruments: A number of satellites are equipped with instruments that can detect CMEs in space. These instruments can measure the speed, density, and magnetic field of CMEs.
- Computer Models: Scientists use computer models to simulate the behavior of the Sun and the solar wind. These models can help them predict when CMEs are likely to occur and how they will propagate through space.
The Importance of CME Research:
Continued research on CMEs is crucial for improving our understanding of space weather and protecting our technology and infrastructure from the impacts of geomagnetic storms. This research includes:
- Developing Better Forecasting Models: Improving the accuracy of CME forecasts is essential for providing timely warnings to operators of critical infrastructure.
- Studying the Physics of CMEs: Understanding the mechanisms that trigger CMEs and govern their propagation is crucial for developing better forecasting models.
- Developing Mitigation Strategies: Developing strategies for mitigating the impacts of geomagnetic storms can help to protect our technology and infrastructure.
By continuing to study CMEs and improve our understanding of space weather, we can better prepare for the challenges and opportunities that arise from the Sun’s activity. The upcoming potential aurora is a great reminder of the connection between our planet and the sun, and the constant need to study and understand these complex interactions.
