On the night of September 27, the Aurora Borealis will be visible from the United States and Canada and will be repeated this week
It has been a long time since Earth’s magnetic activity was strong enough to bring the Aurora Borealis to the United States, but less than two weeks after NASA announced that the sun is moving away from its minimum and officially starting. In a new solar cycle, the people of the United States will have the opportunity to observe the Northern Lights in North America.
The Space Weather Prediction Center (SWPC) has announced G1 and G2 geomagnetic storm warnings for the nights of September 27-29, those clocks are a measure of solar activity reaching Earth’s atmosphere and warnings up to that level indicate that the aurora is too see is in the northern United States.
Current G1 l isolated geomagnetic storm conditions, classified as minor, are likely to continue through September 27-28, as explained in the SWPC advisory.
Aurora Borealis visible from the US
A much larger coronal hole is expected on September 29, further improving solar wind conditions and in parallel, a G2 storm watch has been issued under the moderate rating for September 29.
The map issued by the SWPC reveals the possible southern range of the aurora, but during the G1 warning periods it will be seen when looking south at the green line, and during the G2 warning, you must look for the aurora that is so as far south as the yellow line.
That area north of the Yellow Line includes Northern Idaho, Northern Iowa, Maine, Michigan, Minnesota, Montana, New Hampshire, New York, North Dakota, South Dakota, Vermont, Washington, and Wisconsin, plus everything. Alaska and Canada. The Aurora Borealis isn’t exactly a rare occurrence in Alaska and Northern Canada, however.
