Northern Lights UK Tonight — 1 July 2026: A Second CME Arrival Could Bring a G1 Storm (Chance of G2) — Best Aurora Chance This Week
The aurora stays on the watchlist tonight. After a first CME grazed Earth on 30 June, a second, slower cloud of solar material that left the Sun on 27 June is arriving today, and forecasters say activity could reach G1 (Minor) storm levels tonight (1 July), 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 is still the calendar: early July means barely any darkness, so the window is short. Here's exactly when and where to look.
