A colossal 'hole' in the sun's atmosphere could supercharge Earth's auroras on March 24

A moderate aurora watch is in effect Friday (March 24) for higher latitudes of Earth due to a coronal hole, an opening in the sun's magnetic field, according to the U.S. National Oceanic and Atmospheric Administration (NOAA). When these holes open in the corona, the sun's upper atmosphere, they allow an increased flow of the charged-particle stream known as the solar wind. In similar situations, coronal holes have led to auroral displays as far south as New York and Idaho, according to spaceweather.com.  The sun has been busy in recent months as it climbs toward an expected 2025 peak of its 11-year activity cycle. For example, NASA's Solar Dynamics Observatory recently spotted a gigantic "tornado" swirling across the sun's north pole.

For three days last week, boiling plasma rose high above the sun's surface, peaking at a height of 14 Earths or about 75,000 miles (120,000 kilometers) on March 18. When the tornado collapsed, the ejected material did not fly toward our planet, however. Most solar activity is harmless, boosting auroras and causing minor radio blackouts, but NASA, NOAA and other groups keep a 24/7 watch on the sun just in case. Strong solar storms can occasionally short out satellites or affect electrical power supplies, like a blackout in Quebec, Canada that took place in 1989.
