A powerful geomagnetic storm illuminated skies across northeastern Italy on January 19, producing a rare and unusually intense aurora borealis visible at low latitudes—an event seldom seen over the country.
The phenomenon was documented in a time-lapse sequence by astrophotographer Gigliola Antonazzi of the Antares Astronomical Study Center in Trieste, who recorded the display from Basovizza under strong bora winds and freezing temperatures. According to researchers at Antares, the northern horizon was “suffused with light emitted by atomic oxygen: deep red arcs formed at altitudes above 200 kilometers, while vivid green and aquamarine bands appeared lower in the atmosphere, between 100 and 200 kilometers.”
