Comet Lemmon (C/2025 A6) may soon make a play for the title of “comet of the year” for Northern Hemisphere observers. Discovered in January 2025 and initially thought to be an asteroid, it’s now forecast to be easily visible in binoculars, and possibly to the naked eye, during mid-October. Comet Lemmon will make its closest approach to Earth on Oct. 20–21, coinciding with the dark skies of a new moon and the peak of the Orionid meteor shower. October is also a great month for displays of the Northern Lights, making it a potentially exciting month for skywatchers.
