A bright comet discovered in publicly released images from the Solar Wind Anisotropies (SWAN) camera on the orbiting Solar and Heliospheric Observatory (SOHO) is expected to make observations exciting for amateur astronomers. The comet, designated C/2025 F2 (SWAN), was first reported by Vladimir Bezugly of Ukraine on March 29th and independently confirmed by Michael Mattiazzo of Victoria, Australia.
The comet’s magnitude has been measured at around 9.5, making it visible low in the eastern sky before dawn. Despite its early hour, observers are eager to spot it. The comet is predicted to brighten significantly over the next month, with some predictions suggesting a peak magnitude of 3.6.
Amateur astronomers can observe the comet from locations with an unobstructed view to the northeast. It will be visible in the morning sky until around April 25th, and then move into the evening sky. The best viewing time is expected to be during twilight, when it’s up higher and less affected by the atmosphere.
Comet SWAN has a high northerly declination, making observers in mid-northern latitudes favored. It will pass about 2° north of the Pleiades cluster on May 1st, its perihelion. The comet is expected to make extended appearances for observers in both hemispheres, with the best viewing opportunities in the northern hemisphere until April 25th.
For those interested in tracking the comet, orbital elements are available for download from the Minor Planet Center’s website. Amateur astronomers can use these elements to follow the comet’s movement and plan their observations accordingly.
