WASHINGTON D.C. – April 10, 2026 – A G1 minor geomagnetic storm is impacting Earth today, April 10, 2026, potentially making the aurora borealis visible in up to 10 northern U.S. states. The storm is linked to increased solar wind activity originating from a coronal hole on the sun. This event is currently unfolding, with aurora visibility expected to continue into April 11.
The National Oceanic and Atmospheric Administration (NOAA) Space Weather Prediction Center has been closely monitoring solar activity. Experts at NOAA anticipate G1 minor storming levels for April 10-11. This activity stems from a co-rotating interaction region, where a faster solar wind stream overtakes slower background solar wind. Social media is abuzz with early reports of aurora sightings from enthusiasts in northern latitudes. Verification of these sightings is ongoing.
The phenomenon of the northern lights occurs when charged particles from the sun interact with Earth’s magnetic field. These particles are channeled along magnetic field lines towards the poles. There, they collide with oxygen and nitrogen atoms in the upper atmosphere. These collisions excite the atmospheric gases, causing them to release energy as visible light, creating the dancing aurora displays. Experts emphasize that the southward orientation of the Bz component of the interplanetary magnetic field can enhance the entry of solar energy into Earth’s magnetosphere, increasing the likelihood of visible aurora.
According to NOAA forecasts, the Kp index is expected to reach approximately 5.33. This level is generally sufficient for the aurora to be visible on the northern horizon in far northern states. U.S. states with the best chance of viewing the aurora include Alaska, and the northern parts of Washington, Idaho, Montana, North Dakota, South Dakota, Minnesota, Wisconsin, Michigan, and Maine. While a G2-class storm is not forecast, such an event could extend aurora visibility further south. The Space Weather Prediction Center’s 3-Day Forecast indicates a 55% chance for R1 (Minor) radio blackout levels, with a slight possibility of an isolated R3 (Strong) event. As of April 10, 2026, no significant geomagnetic storms above G1 levels are expected, and no major transient or recurrent solar wind features are forecast.
The potential impacts of this G1 storm are generally minor. These include weak power grid fluctuations and minor impacts on satellite operations. Aurora displays are also a common effect of such storms. NOAA’s Space Weather Prediction Center is providing real-time updates. For those seeking to witness the aurora, experts advise seeking dark skies away from urban light pollution, ideally 30 to 60 minutes outside city limits, and looking towards the northern sky. Using dim red lights can help preserve night vision. The aurora timeline viewer product is currently unavailable, but NOAA’s 3-Day Forecast and its official website, 99newse.com, offer further information.
This is a developing story. More information regarding the extent and visibility of the aurora will be available as the geomagnetic storm progresses through April 11. Future implications are minimal given the G1 classification, but ongoing monitoring by NOAA will continue to assess space weather conditions.
