Northern Lights to Put on Spectacular Show Across the US Tonight

A severe geomagnetic storm is expected to hit the United States tonight, potentially producing spectacular displays of the Northern Lights (Aurora Borealis) visible from almost every state. This phenomenon is caused by a coronal mass ejection (CME) from the Sun, which is expected to interact with Earth's magnetic field and create the dazzling light show.

According to the National Oceanic and Atmospheric Administration (NOAA), the storm has been classified as a G4 severe geomagnetic storm, which is the second-highest level on the scale. This means that the Northern Lights could be seen as far south as Alabama and northern California, and potentially even farther south into states like Texas and Louisiana.

The Space Weather Prediction Center (SWPC), a division of NOAA, has issued a warning about the potential disruption to power grids and satellite communication. During geomagnetic storms, the heat created by the solar activity can increase the density and distribution of particles in the upper atmosphere, causing extra drag on satellites in low-earth orbit. This can also modify the path of radio signals and create errors in GPS positioning information.

Residents in various parts of the country are advised to look northward for the best viewing opportunities. The Northern Lights are best seen in areas with minimal light pollution, such as national parks or remote locations. For those in urban areas, using a camera with low shutter speeds and night mode can help capture the event.

While the exact timing and intensity of the storm are subject to change, forecasters predict that the best viewing times will be between 10 PM and 2 AM. This is because the storm's effects are expected to peak during this period, making it an ideal time for aurora enthusiasts to witness the spectacle.

The current solar cycle is approaching its peak phase, which is expected to bring more frequent and intense solar flares and CMEs. This increased activity has led to a higher likelihood of geomagnetic storms and subsequent aurora displays. As the Sun continues to be active, there will be numerous opportunities for people across the US to witness this natural phenomenon.

For those who miss the current display, there will be plenty of chances to see the Northern Lights in the coming months. The Sun's solar maximum cycle is expected to continue through next July, providing multiple opportunities for aurora sightings.

Where to See the Northern Lights Tonight

The Northern Lights are expected to be visible in a wide range of states, including southern states like South Carolina, Georgia, Alabama, Mississippi, Louisiana, Texas, New Mexico, and Arizona. Even though the lights may be fainter in these regions, they can still be captured with the right equipment.

Residents in northern states have a higher likelihood of seeing the aurora borealis with the naked eye. However, those in central Texas and other southern areas may still be able to capture the event on camera or smartphone if they are in areas with minimal light pollution.

Tips for Viewing the Northern Lights

To increase your chances of viewing the Northern Lights, it is recommended to get away from city lights and any obstructions like buildings or trees. Getting higher in altitude will also improve your chances in lower latitudes.

The best time to view the Northern Lights is between 10 PM and 2 AM. Using low shutter speeds and night mode on your camera can help capture the event, especially if you are using a smartphone.

If you miss the current display, there will be plenty of chances to see the Northern Lights in the coming months. The Sun's solar maximum cycle is expected to continue through next July, providing multiple opportunities for aurora sightings.

Potential Disruptions from the Storm

The severe geomagnetic storm could disrupt power grids and satellite communication. The local heat created by the storm can modify the path of radio signals and create errors in GPS positioning information. Satellite navigation (GPS) may be degraded or inoperable for hours, and radio HF (high frequency) radio propagation may be sporadic or blacked out.

The power grid may also be affected by possible widespread voltage control problems. Some protective systems may mistakenly trip out key assets from the grid, leading to potential disruptions in electrical services.

Spacecraft operations may experience surface charging and tracking problems, requiring corrections for orientation issues. Induced pipeline currents could affect preventive measures, and HF radio propagation may be sporadic.

The official G4 scale projected effects include possible widespread voltage control problems, surface charging issues for spacecraft, induced pipeline currents, and disruptions in HF radio propagation and satellite navigation.
