Does solar minimum mean less space weather? The Sun may be heading towards solar minimum, but space weather isn't going quiet just yet🌞⚡ Discover why space weather events can still occur even as solar activity declines metoffice.gov.uk/blog/2026/d…

We welcome the UK Space Strategy and its recognition of space weather as a key resilience challenge. The Met Office Space Weather Operations Centre delivers trusted space weather services that help organisations prepare for and respond to potential impacts from solar activity
Space might feel far away, but it plays a big part in everyday life, from the satellites that power our phones and sat-nav, to keeping trains and rural areas connected. It’s also crucial for defence, research and innovation. That’s why we’ve launched a new Space Strategy backed by £7.8bn of funding up to 2030.

Congratulations to @eumetsat on the successful launch of MTG-I2, which will provide more rapid observations over Europe and aid weather monitoring and emergency responses. Reaction from our Head of Space Applications Simon Keogh below 👇
MTG-I2 is safely in orbit! 🚀 Launched on Ariane 6, the satellite has deployed its solar panels and is now powered up. Once operational it will refresh imagery over Europe every 2.5 minutes giving forecasters faster views of severe storms and wildfires. bit.ly/4zJhUfm
