A powerful surge from the Sun struck Earth’s magnetic field on January 19, 2026, igniting a vivid display of auroral light over Lublin, Poland. During intense geomagnetic storms, charged particles guided by Earth’s magnetosphere spiral into the upper atmosphere, colliding with oxygen and nitrogen atoms. The dominant green glow seen here is produced by excited atomic oxygen roughly 100 to 300 kilometers above the surface, a signature wavelength that often defines strong auroral events at mid latitudes.

In this upward looking composition, bare winter trees encircle the sky like dark filaments, emphasizing the luminous river of plasma flowing overhead. The contrast between the stark silhouettes and the soft, shifting auroral curtain captures both the violence of solar activity and the quiet stillness of the forest below. Events of this magnitude push the auroral oval far south of its usual polar confines, turning the Polish sky into a temporary canvas painted by space weather.
