A minor geomagnetic storm coincides with the full Strawberry Moon for a rare celestial display
Category: Arts & Culture
Skywatchers across the northern United States are in for a treat tonight as the Northern Lights, or aurora borealis, may be visible in 19 states, including Vermont. This rare opportunity arises from a minor geomagnetic storm rated G1 by the Space Weather Prediction Center, which is linked to the strongest solar flare of 2025. The event coincides with the full Strawberry Moon, promising a spectacular celestial display for those lucky enough to catch it.
The aurora borealis is caused by geomagnetic storms that occur when charged particles from the sun collide with gases in the Earth's atmosphere, creating brilliant waves of light in the sky. Tonight's display is triggered by a coronal mass ejection (CME) that left the sun on June 26, 2026. This cloud of plasma and magnetic material can disturb Earth’s magnetic field, leading to conditions favorable for auroras, especially in regions typically farther south than usual.
According to NOAA's Space Weather Prediction Center, the best chances to see the Northern Lights will be in northern states near the U.S.-Canada border, particularly in Washington, Idaho, Montana, North Dakota, South Dakota, Minnesota, Wisconsin, Michigan, and Maine. Observers in Oregon, Wyoming, Nebraska, Iowa, Illinois, Indiana, Ohio, New York, Vermont, and New Hampshire may also have a chance to glimpse the lights if the geomagnetic storm intensifies. The visibility of the auroras depends significantly on the storm's strength and local conditions.
The Northern Lights are typically most visible between 10 p.m. and 2 a.m. local time, making this timeframe ideal for skywatchers. Skies are expected to be mostly clear tonight, enhancing the potential for viewing. "We typically suggest getting away from cities and finding an open field or hilltop to lay out under the stars and wait for the show to really peak at the late evening or early morning hours," said Tim Brothers, a Technical Instructor and Observatory Manager at the Massachusetts Institute of Technology, in a past interview.
The full Strawberry Moon will rise tonight, which could create a dramatic backdrop for the aurora display. Nevertheless, its brightness might make it harder to see the auroras, particularly if they are faint. The moonlight can reduce the visibility of weaker auroras, so finding a dark location away from urban light pollution is key. Allowing your eyes to adjust to the darkness for about 20 minutes is also recommended, as this can help improve night vision.
The forecast predicts geomagnetic storm conditions to reach G1 (minor) and possibly G2 (moderate) levels. The Kp index, which measures geomagnetic activity on a scale from 0 to 9, is expected to peak at 5. This means that the auroras could potentially extend farther south than usual, depending on the storm's intensity and the interaction with Earth's magnetic field. If the storm strengthens, observers in southern states might also be able to see the lights low on the northern horizon.
For the best chance of witnessing the Northern Lights, skywatchers should seek out dark locations with a clear view of the northern horizon. Rural areas, open fields, and elevated viewpoints are ideal. It's also helpful to monitor real-time tools and apps such as Space Weather Live and My Aurora Forecast to keep track of aurora activity. Cell phone cameras can be particularly useful, as they are often more capable of capturing the colors of the auroras than the naked eye can see. Observers should be patient, as the auroras can vary in intensity and visibility throughout the night.
Tonight's potential display of the Northern Lights offers a unique opportunity for millions across the United States to experience a phenomenon usually reserved for polar regions. Even a minor geomagnetic storm can create an awe-inspiring spectacle that captivates amateur astronomers and casual observers alike. This event showcases the beauty of the auroras and highlights the Sun's influence on Earth's environment. As conditions evolve, skywatchers should remain hopeful yet realistic, as visibility will depend on a combination of solar activity, magnetic field interactions, and local weather conditions.
As anticipation builds for this celestial event, skywatchers across the northern United States should prepare for a night of wonder. Whether or not the Northern Lights make an appearance, the combination of the full Strawberry Moon and the potential for auroras promises a memorable evening under the stars.
