A significant solar storm is on its way to Earth, promising a captivating display of auroras, stretching the possibilities for viewing across more U.S. states than normal. This anticipated event is expected to reach its peak on Tuesday night.
In recent days, the sun has released powerful bursts of energy, known as coronal mass ejections. This has prompted scientists to alert the public with a geomagnetic storm watch. Regions like Alaska, Washington, Oregon, Montana, North Dakota, South Dakota, Minnesota, Michigan, Wisconsin, Vermont, New Hampshire, and Maine could witness the stunning northern lights. Additionally, parts of northern Idaho, Wyoming, Nebraska, Iowa, Illinois, New York, and Pennsylvania may also enjoy the spectacle.
The intensity of the visible auroras will largely depend on how the solar bursts interact with Earth’s magnetic field. Shawn Dahl from NOAA’s Space Weather Prediction Center highlighted that we can expect more opportunities to see these incredible displays throughout the year.
Currently, our sun is in a phase called the solar cycle, which occurs every 11 years. This cycle significantly increases the chances of witnessing colorful displays in unusual areas. Experts anticipate that this period of enhanced solar activity will continue, allowing for many more auroras to light up our skies.
The last significant geomagnetic storm, occurring last spring, was the most powerful in two decades, dazzling viewers across the Northern Hemisphere. Previously, in the fall, another intense solar storm surprised many by bringing auroras to places far from the Arctic Circle, including cities like New York and regions in Germany and the UK.
Typically, the northern and southern lights can be seen near the Earth’s poles, where solar particles collide with our atmosphere. Thanks to the current increased solar activity, sightings of these beautiful lights have made their way deeper into the United States and Europe. Every 11 years, the sun undergoes changes that affect its magnetic field, which leads to these extraordinary light displays.
However, it’s important to remember that solar storms can disrupt communications, including GPS and radio systems crucial for air traffic control. Historically, severe solar storms have caused significant disruptions, such as the 1859 event that ignited telegraph lines and disruptive activities in the coastal waters during the Vietnam War.
While scientists can’t predict solar storms months in advance, they do provide warnings a few days ahead of these powerful events to help people and businesses prepare.
If you’re hoping to catch a glimpse of the northern lights, it’s best to head to a dark location away from city lights, such as a local or national park. Make sure to check local weather conditions, as clouds can obscure the view. Interestingly, even smartphone cameras can sometimes capture the auroras in ways that the human eye cannot.
As Kelly Korreck from NASA puts it, “Enjoy it. It’s this great show… from the sun to you.”
