Northern Lights may dazzle in 14 U.S. states amid geomagnetic storm

In the United States, the Northern Lights, also known as aurora borealis, are expected to be visible overnight on July 2, 2025, due to an incoming coronal mass ejection (CME) that will lead to a minor geomagnetic storm categorized as G1 on a scale from G1 to G5. This event follows a period of several aurora displays in northern states throughout late June. The National Oceanic and Atmospheric Administration’s Space Weather Prediction Center issued a forecast suggesting that the geomagnetic storm will peak during the limited hours of darkness, enhancing the visibility of the aurora across various regions, primarily in the northern parts of the country. Specific states that stand to benefit from this celestial display include Washington, northern Idaho, Montana, Wyoming, North Dakota, South Dakota, Minnesota, Wisconsin, Michigan, Iowa, New York, Vermont, New Hampshire, and Maine. Areas closest to the Canadian border will likely experience the best views, though limited nighttime darkness due to the summer solstice may impede visibility. The bright light of the waxing crescent moon will also pose a challenge, as it will be 43% illuminated on the night of the event. Consequently, individuals hoping to witness the Northern Lights are advised to find locations away from artificial light pollution. Historical trends indicate that the best chances for aurora sightings generally occur following solar maximum phase and in the months surrounding the equinox, which typically heighten geomagnetic activity. As such, the geomagnetic storm is expected to coincide with the evening hours on July 2, providing a significant opportunity for skywatchers and aurora enthusiasts alike. While predictions can always change, the increasing likelihood of auroral displays following CME events has garnered interest among both casual observers and professional aurora chasers. As the solar cycle transitions past its solar maximum, there could be more opportunities for sightings over the next couple of years. This week, excitement builds with the possibility of not just seeing the Northern Lights but also spotting the Milky Way galaxy, as its visibility peaks during early July.
