The northern lights, or aurora borealis, are a breathtaking natural phenomenon that captivates many. Recently, they were visible across parts of the UK, sparking curiosity about their causes and how to best view them. This page answers common questions about the northern lights, including their scientific background and tips for optimal viewing.
-
What causes the northern lights?
The northern lights are caused by charged particles from the Sun colliding with gases in Earth's atmosphere. This interaction creates stunning displays of light, primarily in the polar regions. A recent coronal mass ejection from the Sun has increased the chances of seeing these lights even in lower latitudes, such as the UK.

When is the best time to see the aurora borealis?
The best time to see the aurora borealis is during the winter months when nights are longer and skies are darker. However, recent solar activity can lead to sightings at other times, as seen on the nights of September 12 and 13, 2024, when the lights were visible across the UK.

How can I view the northern lights in the UK?
To view the northern lights in the UK, find a location with low light pollution and clear skies. Areas in Scotland, Northern Ireland, and northern England are ideal. It's also recommended to check local forecasts for solar activity and weather conditions to increase your chances of witnessing this spectacular event.
-
What are the scientific explanations behind auroras?
Auroras occur when charged particles from the Sun interact with Earth's magnetic field and atmosphere. These particles excite gas molecules, causing them to emit light. The colors of the aurora depend on the type of gas involved; for example, oxygen produces green and red hues, while nitrogen can create blue and purple shades.
-
Why are the northern lights visible in lower latitudes now?
The visibility of the northern lights in lower latitudes, such as the UK, is often due to increased solar activity, including coronal mass ejections. These events can send a surge of charged particles toward Earth, enhancing the likelihood of auroras appearing further south than usual.
-
What should I bring to see the northern lights?
When planning to see the northern lights, bring warm clothing, a camera with a tripod for long exposure shots, and possibly binoculars or a telescope for a closer view. Snacks and hot drinks can also make your viewing experience more enjoyable while you wait for the lights to appear.
