Northern Lights UK Tonight — G2 Geomagnetic Storm Watch for 28 August 2026 as Earth-Directed CMEs Arrive
The northern horizon is live again tonight. NOAA has a G2 (Moderate) geomagnetic storm watch running for 28–29 August after an M6.9 solar flare from region AR4513 fired Earth-directed coronal mass ejections our way, with a coronal hole stream adding to the mix. The Met Office says aurora may be visible over Scotland — especially the north — with a chance for parts of northern England and Northern Ireland if skies stay clear. It's a decent, northern-leaning event rather than a nationwide spectacle, but here's the good news the summer alerts didn't have: with late August, proper darkness has returned to the UK, so if the storm times its arrival with a clear night you've got a real chance. Here's when and where to look.
