Northern Lights UK Tonight — 30 June 2026: A CME Arrival Could Bring a G1 Storm (Chance of G2) — Best Aurora Chance This Week
The aurora is back on the watchlist. A cloud of solar material (a CME) that left the Sun on 26 June is grazing Earth today, and forecasters say it could lift geomagnetic activity to G1 (Minor) storm levels tonight (30 June), with an outside chance of G2 (Moderate). Northern Scotland and the Northern Isles are the prime spots, with a camera-only chance further south if it peaks. The catch this time is the calendar: late June means barely any darkness, so the window is short. Here's exactly when and where to look.
