Overview
- Colorful displays were documented on the night of Oct. 19–20 across states including Brandenburg, Mecklenburg-Vorpommern, Schleswig-Holstein and Saxony under unusually clear skies.
- The Deutscher Wetterdienst said dry, transparent air enabled the views and noted that further sightings were only likely where skies stayed cloud-free as cloud cover increased by Tuesday, with the northwest turning too cloudy.
- NASA and astronomy groups had flagged a medium-strength solar storm and a coronal mass ejection as the drivers pushing aurora visibility farther south than usual.
- Comet C/2025 A6 (Lemmon) was visible near peak brightness around Oct. 21 and was photographed alongside the aurora, while the fainter C/2025 R2 (Swan) remained a binocular or telescope target.
- The Orionid meteor shower reaches its maximum Oct. 21–22 with roughly 10–20 meteors per hour under dark, clear skies, helped by the new moon.
