If you’re yet to see Comet Lemmon (C/2025 A6) and Comet SWAN (C/2025 R2), here comes a final easy chance before they get drowned out by strong moonlight. With the moon approaching its half-lit, first quarter phase on Wednesday, Oct. 28, 2025, these icy visitors from the edge of the solar system will become harder to find with binoculars and transition to telescopic objects. Visible in the northeast and south, respectively, Lemmon and SWAN are now in their post-closest approach phase and drifting farther from Earth, with Lemmon closing in on its perihelion on Nov. 8, when it will swing closest to the sun.
