Occasionally, you may have the opportunity to witness the Northern Lights from your home in the UK or US. Tonight (Wednesday, July 24) presents a moderate chance of seeing these mesmerizing lights.
Typically, the Northern Lights are only visible in countries like Canada, Russia, and Sweden, but they have been spotted from as far as Penzance in Cornwall earlier this year.
While it’s rare for the lights to reach Cornwall, seeing the Northern Lights from the UK is not uncommon, although it requires a severe geomagnetic storm, which is a rare occurrence.
When can I see the Aurora tonight?
The Space Weather Forecast suggests that a solar storm may hit the Earth this week, potentially making the Northern Lights visible in parts of the UK on Wednesday, July 24.
Unfortunately, the Northern Lights can only be seen in certain parts of the UK, such as the north of England and Northern Ireland.
In the United States, it may be visible across several northern and upper Midwestern states from New York to Idaho.
However, due to the season, the window for viewing the Northern Lights is limited.

How to increase your chances of seeing the Aurora
To enhance your chances of witnessing the Northern Lights, it is advisable to move away from urban areas with clear skies and minimal light pollution.
Locate a north-facing shoreline for the best viewing experience with fewer obstructions and less light pollution.
What Causes the Northern Lights?
The Aurora Borealis occurs when high-energy particles from the Sun collide with lower-energy particles in the Earth’s atmosphere.
Geomagnetic storms can push the Aurora further south, making them visible in regions where they are not usually seen.
These storms are more likely to occur during the waning stages of a solar cycle, when coronal holes generate high-speed solar wind that disrupts Earth’s magnetic field.
Why do the auroras have different colors?
The color of the Northern Lights can vary based on the atoms in Earth’s atmosphere reacting with the Sun’s energy.
Green auroras are produced by high-altitude oxygen atoms, while blue, yellow, or red auroras indicate lower-altitude oxygen or nitrogen atoms colliding with solar particles.
What does “Aurora” mean?
The term “Aurora Borealis” roughly translates to “North Wind Dawn” and is a nickname for the Northern Lights. Boreas is the god of the north wind in ancient Greek mythology.
The Southern Lights are also known as “Aurora Australis”, translating to “southern wind dawn”. These lights can be influenced by geomagnetic storms and have been seen in locations like New Zealand and Australia.
