A significant geomagnetic storm is currently impacting Earth, raising the possibility of spectacular aurora displays – commonly known as the Northern Lights – across a wider swath of the United States than typically observed. The event, triggered by recent solar activity, could make the aurora borealis visible as far south as Illinois and Oregon, offering a rare opportunity for millions to witness this natural phenomenon. Understanding the science behind these displays and knowing where to look are key to maximizing your chances of seeing the lights.
The current display is a result of coronal mass ejections (CMEs) – eruptions of solar energy – impacting Earth’s magnetic field. According to the National Oceanic and Atmospheric Administration (NOAA), This represents a powerful geomagnetic storm, prompting a “severe” geomagnetic storm watch for Tuesday, November 12th and Wednesday, November 13th, 2025. While solar storms aren’t uncommon, the intensity of these recent bursts is considered rare, creating conditions ripe for widespread aurora visibility. The Space Weather Prediction Center is actively tracking the situation and providing updated forecasts.
What Causes the Northern Lights?
The aurora borealis and its southern counterpart the aurora australis, are created when charged particles from the sun collide with atoms and molecules in Earth’s atmosphere. These collisions release energy in the form of light, resulting in the vibrant colors often seen – predominantly greens and reds, but sometimes similarly purples. The intensity and visibility of the aurora are directly linked to the strength of the solar activity and the resulting disturbances in Earth’s magnetic field. The Planetary K Index, currently being monitored by NOAA, is a key indicator of geomagnetic activity; a higher Kp index suggests a greater chance of seeing the aurora.
According to the NOAA’s Aurora Dashboard, as of today, February 18, 2026, the Solar Wind Speed is 691 km/sec. While specific values for Bt and Bz are currently unavailable, these magnetic field components play a crucial role in determining the aurora’s intensity and location. The Noon 10.7cm Radio Flux is currently at 118 sfu, another indicator of solar activity.
Which States Could See the Aurora?
While predicting aurora visibility is inherently challenging, current forecasts suggest that the following states have the highest potential for seeing the Northern Lights on Tuesday night and Wednesday night: Washington, Oregon, Montana, Idaho, Wyoming, North Dakota, South Dakota, Minnesota, Wisconsin, and Illinois. But, even states further south may experience a faint glow on the northern horizon under optimal conditions. Light pollution is a significant factor, so escaping to darker, rural areas will greatly increase your chances of a successful viewing.
Potential Disruptions from the Geomagnetic Storm
While the aurora provides a stunning visual display, powerful geomagnetic storms can also have disruptive effects on technology. Intense solar storms can threaten power grids and communication systems, as highlighted by recent events. In December 2025, the BBC reported that approximately 6,000 planes were grounded by Airbus due to potential interference from intense solar radiation, requiring a software update after one aircraft experienced a “sudden drop in altitude.” This underscores the potential impact of space weather on air travel. The Carrington Event of 1859, the most intense geomagnetic storm in recorded history, caused electricity to be generated in telegraph wires, resulting in shocks for operators and sparking pylons.
The Independent reported on a large solar radiation storm in over two decades, which could trigger the aurora. The potential for disruption to GPS signals and orbital infrastructure is also a concern.
How to Best View the Aurora
To maximize your chances of seeing the Northern Lights, discover a location away from city lights with a clear view of the northern horizon. Check the aurora forecast from resources like LightsWatch for real-time updates on the KP index and solar wind data. Allow your eyes to adjust to the darkness for at least 20-30 minutes. Patience is key, as the aurora can be unpredictable. Dress warmly, as viewing often involves spending time outdoors in cold temperatures.
The current geomagnetic activity presents a unique opportunity to witness a breathtaking natural display. While the potential for technological disruptions exists, the chance to see the Northern Lights from a wider range of locations makes this a particularly exciting event for aurora enthusiasts and casual observers alike.
Looking ahead, increased solar activity is expected to continue throughout 2025 and beyond, suggesting further opportunities to observe the aurora. Continued monitoring of space weather conditions by NOAA and other agencies will be crucial for both appreciating the beauty of the aurora and mitigating potential risks to our technological infrastructure.
