Comet C/2025 A6 (Lemmon) Dazzles over Arizona
Astrophotographer Chris Schur: "This is my best shot of the Comet Lemmon A6 so far with the RASA8. While there were no significant knots in the tail on this evening, the gas tail was brilliant and structured. Comet C/2025 A6 Lemmon, October 24, starting at 7:00pm MST (2:00UT 10/25)."
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.
Arizona is a landlocked state in the Southwestern region of the United States, sharing the Four Corners region of the western United States with Colorado, New Mexico, and Utah. It also borders Nevada to the northwest and California to the west, and shares an international border with the Mexican states of Sonora and Baja California to the south and southwest.
