Overview

• Overnight into Tuesday, striking displays were observed across Schleswig-Holstein and Mecklenburg-Vorpommern, especially in coastal spots like Dagebüll and Zingst.
• Regional forecasts and current measurements had flagged a high probability for northern viewers before the show began.
• Witnesses reported red skies with yellow and green tones and noted bright, dancing arcs over the North and Baltic Seas.
• Spaceweather.com and other coverage reported no solar storm and pointed to equinox coupling as the driver, while a separate outlet attributed the lights to a solar storm.
• The spectacle comes during an active phase of Solar Cycle 25 that has produced more frequent geomagnetic disturbances in Europe.
