G1 Geomagnetic Storm May Bring Northern Lights to Northern US This Weekend

A fast stream of solar wind originating from a large coronal hole in the sun's atmosphere is expected to trigger minor G1 geomagnetic storm conditions from May 15 through May 17, 2026. According to NOAA's Space Weather Prediction Center, this space weather event could enhance aurora visibility across parts of the northern United States, potentially extending as far south as northern Michigan and Maine. The peak activity is anticipated between 11 p.m. and 2 a.m. EDT (0300-0600 GMT) over the next few nights. While states like Alaska, North Dakota, Minnesota, Wisconsin, Michigan, and Maine have the highest probability of sightings, visibility remains dependent on local conditions such as cloud cover, darkness, and magnetic field responses. Experts caution that auroras are unpredictable, and sightings are not guaranteed even during storm conditions. This phenomenon offers stargazers in the northern U.S. a rare opportunity to witness the northern lights outside their typical high-latitude range, driven by the interaction between the solar wind and Earth's magnetic field.
