This weekend offers the last best chance to see the two green comets before they’re lost in a brightening moon. On Saturday, Oct. 25, Comet Lemmon (C/2025 A6) continues westward, entering the constellation Serpens in the northwestern sky, while Comet SWAN (C/2025 R2) hangs below the Summer Triangle stars in the south, near Saturn. It’s the best remaining night to catch them before they fade and the 16 %-lit waxing crescent moon begins to bleach the twilight sky.
