Overview
- The comet made its closest pass to Earth on October 21 at roughly 101 million kilometers, with the best evening views expected from October 25–31 and continuing into early November in some locations.
- Recent observations show two distinct tails—a blue ion tail and a yellowish dust tail—accompanied by a greenish coma characteristic of diatomic carbon.
- Viewing is favorable across northern latitudes, including Spain, Mexico and much of Central America, while conditions improve for the Southern Hemisphere in November.
- Smartphone photography guidance includes using a tripod or stable surface, enabling night or astrophotography modes, setting ISO to 1600–3200, using 5–10 second exposures and selecting the lowest available aperture.
- Another comet, SWAN (C/2025 R2), may be visible around the same period in some skies, offering a rare opportunity to observe two comets on the same evening.
