NOAA Predicts Northern Lights Visibility Due to Geomagnetic Storm Impacting Northern U.S.
A significant geomagnetic storm, triggered by a full-halo coronal mass ejection (CME) from the sun, is expected to impact Earth early to midday on Tuesday. This event may make the Northern Lights visible across large portions of the northern United States. The National Oceanic and Atmospheric Administration (NOAA) Space Weather Prediction Center (SWPC) announced the event following an M8.1-class solar flare, indicating that periods of G3 geomagnetic storming are likely. The storm coincides with heightened solar activity at the peak of the sun's 11-year cycle. Residents in Alaska and the northernmost sections of Washington, Idaho, Montana, Wyoming, North Dakota, South Dakota, Minnesota, Wisconsin, Michigan, New York, Maine, Vermont, and New Hampshire may have the best chances to witness the aurora. Sightings are most likely in dark, rural areas far from city lights, best viewed facing the northern horizon after sunset and before sunrise.
