Comet C/2025 A6 (Lemmon) and Aurora Borealis: New View from Sweden

Astrophotographer Peter Rosen: "It’s not often you swear at the northern lights. But tonight I wanted to photograph Comet Lemmon—and then a damn aurora showed up and ruined the shot. Still, maybe it turned out alright after all. Abisko tonight."😄

Comet Lemmon is brightening and moving into morning northern skies. Besides Comet SWAN25B and Comet ATLAS, Comet C/2025 A6 (Lemmon) is now the third comet currently visible with binoculars and on long camera exposures. Comet Lemmon was discovered early this year and is still headed into the inner Solar System. The comet will round the Sun on November 8, 2025. It passed nearest to the Earth—about half of the Earth-Sun distance—on October 21.

Earth auroras have different names depending on the pole they occur at. Aurora Borealis, or the northern lights, is the name given to auroras around the north pole and Aurora Australis, or the southern lights, is the name given for auroras around the south pole.

Abisko is a village in Sápmi (Lapland), in northern Sweden, roughly 200 km north of the Arctic Circle. Sweden, formally the Kingdom of Sweden, is a Nordic country located on the Scandinavian Peninsula in Northern Europe. It borders Norway to the west and north, and Finland to the east.
