Increased Visibility of the Aurora Borealis

The aurora borealis, or Northern Lights, has been unusually visible in recent months, with sightings reported much further south than usual, including parts of the UK, Germany, and even New Mexico.

Cause of the phenomenon: The aurora borealis is caused by interactions between charged particles from the sun and the Earth's magnetic field and atmosphere.

Solar maximum: The increased aurora activity is attributed to the current period of heightened solar activity, known as solar maximum. This period is expected to last until mid-2025, potentially extending into 2026.

Potential impact of solar storms: While the aurora borealis is a beautiful spectacle, the strong solar storms responsible for it can also cause disruptions to power grids, radio signals, and satellite communications

Solar cycle: The sun goes through an 11-year cycle of activity, with periods of high activity (solar maximum) and low activity (solar minimum).

Coronal mass ejections (CMEs): These are large bursts of energy and charged particles ejected from the sun's corona. When directed towards Earth, CMEs can cause geomagnetic storms.

Geomagnetic storms: These are disturbances in Earth's magnetic field caused by interactions with the solar wind, particularly during periods of high solar activity.

Aurora formation: The colourful lights of the aurora borealis are produced when charged particles from the sun collide with gases in Earth's upper atmosphere.

Viewing tips: The best time to see the aurora borealis is during the night, away from city lights. Clear skies and periods around the spring and fall equinoxes are generally considered ideal for viewing.

The increased visibility of the aurora borealis in recent months is a direct result of heightened solar activity. While this provides a unique opportunity to witness a spectacular natural phenomenon, it also highlights the potential impact of solar storms on our technological infrastructure. It is important to stay informed about space weather forecasts and potential disruptions, especially during the remaining period of solar maximum.
