The Wandering Tail of Comet C/2025 A6 (Lemmon): View from Spain

The Wandering Tail of Comet C/2025 A6 (Lemmon): View from Spain

What has happened to Comet Lemmon's tail? 

The answer is blowing in the wind—the wind from the Sun in this case. This continuous outflow of charged particles from the Sun has been quite variable of late. As the Sun emits bursts of energy via what are called coronal mass ejections (CMEs), this pushes out and deflects charged particles emitted by the comet itself. The result is a blue hued ion tail for Comet C/2025 A6 (Lemmon) that is impressively intricate.

This long-duration composite image was taken from Alfacar, Spain last month. Comet Lemmon is now fading as it heads out away from the Earth and Sun and back into the outer Solar System. Comet Lemmon was discovered early this year. It rounded the Sun on November 8, 2025. Comet Lemmon passed nearest to the Earth—about half the Earth-Sun distance—on October 21.

Image Description: A starfield is shown above a mountain peak. Just above the mountain and extending up toward the upper right is a blue-tinted tail of a comet. The comet's head is just to the left of the peak.
