### Northern Lights Alert: A Celestial Spectacle Across the U.S. This Weekend This weekend, a rare opportunity to witness the Aurora Borealis, or Northern Lights, is expected as geomagnetic storms sweep across the northern United States. Forecasters predict that up to **18 states** may experience this stunning natural phenomenon, particularly on the night of June 15, 2025. The geomagnetic activity is classified as "minor" to "moderate," which enhances the chances of seeing the auroras, especially in states like Idaho, Montana, and New York. This event is particularly notable as it occurs during a time when auroral displays are less common due to seasonal changes in solar activity [https://www.forbes.com/sites/tylerroush/2025/06/15/northern-lights-forecast-10-states-may-see-aurora-borealis-tonight-amid-geomagnetic-storms]. ### Understanding the Aurora Borealis Forecast 1. **Geomagnetic Storms**: The auroras are caused by solar storms that interact with the Earth's magnetic field. This weekend's storms are expected to be of "minor" to "moderate" intensity, which is conducive to auroral visibility [https://www.moneycontrol.com/science/aurora-borealis-rare-sight-expected-this-weekend-when-and-where-to-watch-article-13123586.html]. 2. **Visibility Across States**: The Northern Lights may be visible in **up to 18 states**, including Idaho, Montana, and New York. This broad visibility is due to the strength of the geomagnetic storms [https://indianexpress.com/article/technology/science/aurora-borealis-geomagnetic-storm-visible-in-us-10066318]. 3. **Timing and Conditions**: The best time to view the auroras is expected to be on the night of June 15, with optimal viewing conditions likely occurring after sunset. Clear skies will enhance visibility [https://www.forbes.com/sites/conormurray/2025/06/13/northern-lights-forecast-these-10-states-could-see-aurora-borealis-tonight]. ### Supporting Data on Aurora Visibility - **States Likely to See Auroras**: - Idaho - Montana - New York - Other northern states (totaling up to 18) [https://www.usatoday.com/story/news/nation/2025/06/12/northern-lights-forecast/84177612007]. - **Geomagnetic Storm Ratings**: - Minor to Moderate (G1-G2) storms are expected, which typically allow for auroras to be seen further south than usual [https://www.forbes.com/sites/tylerroush/2025/06/12/northern-lights-forecast-aurora-borealis-may-appear-in-these-states-tonight-as-minor-geomagnetic-storms-near]. ### Conclusion: A Unique Opportunity to Witness the Northern Lights In summary, the upcoming weekend presents a **unique opportunity** for residents in the northern U.S. to witness the Aurora Borealis due to expected geomagnetic storms. 1. **Geomagnetic Activity**: Minor to moderate storms will enhance visibility. 2. **Widespread Visibility**: Up to 18 states may experience the auroras, particularly on June 15. 3. **Optimal Viewing Conditions**: Clear skies post-sunset will provide the best chances for viewing.
