The two green comets continue to shine brightly in twilight each evening for lucky skywatchers with binoculars in the Northern Hemisphere. For observers on Friday, Oct. 24, the bright Comet Lemmon (C/2025 A6) continues to travel westward through the constellation Boötes in the northwestern sky while the dimmer Comet SWAN (C/2025 R2 (SWAN)) hangs below the Summer Triangle stars in the southwest. It’s the best remaining night to see them because they’re now receding from Earth — and the 10%-lit waxing crescent moon will brighten later in the week, bleaching the night sky and making the comets harder to see.
