Stargazers across the northern United States are in for a treat as a "G1 (Minor)" geomagnetic storm is expected to bring the Northern Lights (Aurora Borealis) to lower latitudes. NOAA’s Space Weather Prediction Center has issued a watch for March 6 and 7, 2026. The phenomenon is caused by a high-speed solar wind interacting with Earth’s magnetic field.
States near the Canadian border, including Washington, Idaho, Montana, North Dakota, Minnesota, and Maine, have the best chance of seeing the display. If the storm intensifies, the aurora could be visible as far south as New York or South Dakota. Experts recommend finding a dark location away from city lights for the best viewing experience.
The timing of this solar event is fortuitous for astronomers, following a total lunar eclipse earlier in the week. We are currently just past the peak of a solar cycle, which explains why there have been frequent and vibrant aurora displays over the last two years.
Scientists use the "Kp-index" to measure geomagnetic activity, and forecasters expect it to reach a level of 4.67 tonight. At this level, the aurora usually appears as a faint green glow on the northern horizon, though it can sometimes burst into vibrant colors and pillars of light.
For those unable to see it in person, several online observatories and photographers will be livestreaming the event. Space weather experts remind the public that while minor storms like this are harmless, they can occasionally cause slight fluctuations in power grids or satellite communications.
SUMMARY
G1 geomagnetic storm to bring Northern Lights to the northern U.S. this weekend.
Best viewing expected in states near the Canadian border, such as Minnesota and Maine.
High-speed solar wind from the Sun’s current peak cycle is the cause.
Stargazers encouraged to find dark locations away from urban light pollution.
Minor storm poses no threat but may cause slight satellite fluctuations.
HISTORY
The last two years have been exceptionally active for solar events, as the Sun moved through "Solar Maximum" in its 11-year cycle. This has led to numerous aurora displays visible much further south than usual.
May 2024: One of the strongest solar storms in decades makes aurora visible in Florida.
October 2025: Vibrant "crimson" aurora seen across the Midwest.
January 2026: A series of solar flares triggers multiple geomagnetic storm watches.
March 3, 2026: A total lunar eclipse provides a backdrop for recent solar activity.
March 6, 2026: New G1 watch issued for the first weekend of the month.
