Comet C/2025 A6 (Lemmon): View from Italy

Astrophotographer Alessandro Carrozzi: "Visible low on the northwestern horizon just after sunset, Comet Lemmon appears quite bright, easily observable with a simple pair of binoculars. In the image, in addition to the long ion tail, a beautiful dust tail is now also evident. The long exposure results in a slightly limited level of fine detail, but still allows for a clear appreciation of the comet’s overall structure."

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, but first it will pass its nearest to the Earth—at about half the Earth-Sun distance—on October 21.
