Northern Lights UK This Week — G2 Geomagnetic Storm Watch for Friday 3 July 2026 After X-Class Solar Flare Fires a CME at Earth
The aurora watch just stepped up a gear. An X1.1 solar flare — the strongest of the summer so far — erupted on 30 June and hurled a huge cloud of solar material directly at Earth, travelling at roughly 1,500 kilometres per second. NOAA has issued a G2 (Moderate) geomagnetic storm watch for Friday 3 July, strong enough to push the aurora over Scotland and give northern England a camera chance. The catch remains the calendar: early July means barely any darkness, so the window is short. Here's exactly when and where to look.
