Are you ready to spot two green comets? Visible in the pre-dawn hours for some weeks, the brightest of two comets now in the night sky — Comet Lemmon — on Sunday, Oct. 12, 2025, should become easier to see. A diffuse fuzzy patch in the northwestern sky in binoculars, Lemmon is joined by the slightly less bright Comet SWAN in the southwest in the post-sunset night sky. Both comets will likely brighten through the week as the moon recedes from the evening sky, reaching their brightest around Oct. 20-21 as the Orionid meteor shower peaks. Here’s how to find C/2025 A6 (Lemmon) — and perhaps C/2025 R2 (SWAN) — on Sunday, Oct. 12, 2025.
