What's happened
Multiple sources report a rare geomagnetic storm causing the Aurora Borealis to be visible as far south as Norfolk, UK, on March 21, 2026. Forecasters expect the lights to be visible again tonight, driven by recent solar activity and coronal mass ejections, with optimal viewing conditions in dark, clear skies.
What's behind the headline?
The recent surge in geomagnetic activity is primarily driven by a significant coronal mass ejection from the sun, which has caused a strong geomagnetic storm. This storm has temporarily extended the visibility of the Northern Lights into southern UK regions, an event that is both rare and scientifically predictable given current space weather forecasts. The occurrence around the spring equinox is consistent with the Russell-McPherron effect, which enhances auroral activity during this period. The forecast indicates that the geomagnetic activity will persist, making further sightings likely tonight, especially in areas with clear, dark skies. This event underscores the direct impact of solar activity on Earth's atmosphere and technological systems, as well as the importance of space weather monitoring for both scientific and public interest.
How we got here
The Aurora Borealis occurs when charged particles from the sun, ejected during coronal mass ejections, interact with Earth's magnetic field and atmosphere. This phenomenon is typically seen near the Arctic but can be visible further south during strong geomagnetic storms. The recent solar activity, including a G2 storm and the spring equinox, has increased the likelihood of such displays in the UK and beyond.
Our analysis
The Independent, Sky News, BBC News, and SBS all report on the recent geomagnetic storm and aurora sightings. The Independent emphasizes the rarity of the event and the role of coronal mass ejections, while Sky News highlights the spectacular visual display and the influence of solar activity. BBC News notes the connection to the spring equinox and the potential for further sightings tonight, providing a comprehensive overview. SBS discusses the impact of solar storms on technology and migratory animals, adding depth to the understanding of space weather effects. The consensus across sources confirms the event's significance and scientific basis, with some variation in focus from visual spectacle to technological impact.

coronal mass ejection - Significant release of plasma and magnetic field from the solar corona
A coronal mass ejection (CME) is a significant ejection of plasma mass from the Sun's corona into the heliosphere. CMEs are often associated with solar flares and other forms of solar activity, but a broadly accepted theoretical understanding of these relationships has not been established. If a CME enters interplanetary space, it is sometimes referred to as an interplanetary coronal mass ejection (ICME). ICMEs are capable of reaching and colliding with Earth's magnetosphere, where they can cause geomagnetic storms, aurorae, and in rare cases damage to electrical power grids. The largest recorded geomagnetic perturbation, resulting presumably from a CME, was the solar storm of 1859. Also known as the Carrington Event, it disabled parts of the newly created United States telegraph network, starting fires and electrically shocking some telegraph operators. Near the time in the Sun's eleven-year solar cycle known as solar maxima, the Sun produces about three CMEs daily, whereas near solar minima, there is about one CME every five days.
