Overview

• Comet C/2025 F2 (SWAN), discovered using the SWAN instrument aboard SOHO, is currently visible in the pre-dawn sky for Northern Hemisphere observers.
• The comet, glowing green due to diatomic carbon emissions, has an apparent magnitude of +8, requiring binoculars or a telescope for viewing.
• Its perihelion, or closest approach to the Sun, is expected on May 1, 2025, potentially altering its brightness or causing its disintegration.
• Observers can track the comet as it moves from the Great Square of Pegasus toward Andromeda, with its position aiding visibility through April.
• Predictions suggest the comet might brighten to magnitude +5 post-perihelion, transitioning to evening visibility, though its fate remains uncertain.
