Overview

• Comet C/2025 F2 (SWAN) was officially designated on April 8, 2025, after its discovery in late March using imagery from the SWAN instrument aboard the SOHO spacecraft.
• The comet is currently visible in the early morning sky near the Great Square of Pegasus at a magnitude of +8, requiring binoculars or a telescope to observe.
• It displays a distinctive green hue and a slender tail, with long-exposure images revealing more detail than is visible through telescopes alone.
• The comet is on a trajectory toward the Sun, with its closest approach, or perihelion, expected on May 1, 2025, when it may brighten significantly if it survives solar heating.
• This discovery highlights the collaboration between amateur astronomers, like Michael Mattiazzo, and professional observatories in tracking and studying celestial phenomena.
