A spectacular display of the aurora borealis – often called the Northern Lights – could be visible across a wide swath of North America Monday night. The potential for vibrant auroras follows a significant disruption in the Earth’s magnetic field, according to a forecast issued by the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center.
Geomagnetic Storms and Their Impact
The current forecast comes as intense geomagnetic and solar radiation storms are underway. Shawn Dahl, service coordinator at the Space Weather Prediction Center, indicated the storm is not expected to diminish in intensity until sometime Tuesday.
While the aurora is a beautiful phenomenon, geomagnetic storms can have practical consequences. The U.S. Geological Survey notes these storms have the potential to interfere with satellite operations, GPS communications, and other critical infrastructure.
Potential for Disruption
The effects of these storms aren’t limited to Earth. Solar radiation storms can also impact objects in space and certain communication systems. However, according to Dahl, astronauts currently stationed at the International Space Station are not considered to be at risk.
If the storm continues on its current trajectory, it could lead to further disruptions in satellite and communication systems. It is also possible the aurora will remain visible across a broad geographic area throughout Tuesday. However, the storm’s intensity is expected to decrease at some point, which may limit the extent and duration of both the auroral display and any potential disruptions.
Frequently Asked Questions
What causes the aurora?
The aurora is caused by disturbances in the Earth’s magnetic field, resulting from solar activity.
Could this storm affect my GPS?
Geomagnetic storms can interfere with GPS communications, according to the U.S. Geological Survey.
Are astronauts in danger?
Shawn Dahl said astronauts at the International Space Station are currently not at risk.
Considering the potential for both stunning natural displays and possible technological impacts, how will you prepare for and observe this unique space weather event?
