A close-up shot of Comet C/2025 A6 (Lemmon) captured by Petr Horálek on Oct 18, from the shore of Seč Lake, Czech Republic.
The G2 geomagnetic storm that day, caused by a CME ejected by the Sun few days earlier, disrupted the comet's long wispy ion tail, but not the shorter and thicker white dust tail.
