Partial solar eclipse seen across southern UK

What's happened

A partial solar eclipse has been observed across southern parts of the UK as the Moon covers around 90% of the Sun in London and nearby areas. Observers are advised to use ISO-certified eclipse glasses and consider indirect viewing methods for safety. The event marks the greatest coverage in the UK since 1999, with the next deep partial eclipse not expected until 2050.

What's behind the headline?

Key considerations

• The UK is witnessing its most substantial solar eclipse coverage since 1999, with roughly 90% of the Sun obscured for southern observers.
• Viewing safety is emphasised by health authorities, with recommendations to use certified eclipse glasses and avoid looking directly at the Sun without protection.
• This event provides an opportunity to engage the public in science literacy, particularly around astronomical phenomena and safe observing practices.

What this means now

• The event is unfolding in real time, with observers across London and southern England prepared for peak coverage in the early evening. This will create notable changes in light and temperature locally, underscoring public interest in astronomical events.

Longer-term context

• The next UK-visible total solar eclipse will not occur until 2090, leaving a 64-year gap before the next major alignment is observable from the UK. Educational and safety messaging will likely persist in future celestial events.

How we got here

The upcoming eclipse is the latest in a string of celestial events attracting public attention. Royal Museums Greenwich has issued guidance on safe viewing and eye protection, including the use of eclipse glasses and pinhole viewers. Local residents have prepared viewing spots and educational outreach has increased awareness of solar observation.
