Yet another outstanding image of Comet C/2025 A6 (Lemmon) by Petr Horálek taken on October 18, from the shore of Seč Lake, Czech Republic.

The pic also captures the aurora caused by a G2 geomagnetic storm that day and the storm's effect on the comet's long ion tail.
☄️
Also, watch the reflections.

Camera: Canon Ra, Sigma Art 50mm, f 1.4, ISO 4000, 43x8s.

Instagram post by Petr:
SOLAR WIND IN COMET'S TAIL AND EARTH'S SKY: Yesterday evening, a truly unusual view was possible to capture from Seč Lake, Czech Republic. CME from the Sun hit the Earth, producing a G2 geomagnetic storm, including faint auroras even in mid-latitudes. As the comet C/2025 A6 Lemmon approaches Earth (in 2 days), the same cloud from the sun affected even the complicated ion tail of the comet. I succeeded with deeper imaging to reveal that moment in the tail as well as the aurora itself. It doesn't happen every day to capture the invisible solar wind in two sky phenomena at the same moment!
