Aurora Comet Lemmon

Last night was incredible. I have just moved to Sweden, where I organize astrophotography workshop for a group, and this is the view of nature offered over Suotojärvi Lake. The comet C/2025 A6 Lemmon was seemingly swimming in bright Aurora Borealis. The comet was so bright that we could see it with our naked eyes, even very low over the horizon. Captured after 20:30 UTC.
