Comet C/2025 K1 ATLAS fragmentation: a new image – 9 Dec. 2025.
We imaged comet C/2025 K1 ATLAS and its fragments again under good sky conditions, as part of our follow-up program on this object.
Comet C/2025 K1 ATLAS: 09 Dec. 2025.
The image above comes from the sigma-clipping combination of 19, 60-second unfiltered exposures, remotely taken with the Celestron C14+Paramount ME+SBIG ST-10XME robotic unit available as part of the Virtual Telescope Project in Manciano, Italy. Sky conditions were very good.
Our image shows something very similar to what was seen on 6 Dec. via the Gemini North 8.1-meter telescope. We spotted two fainter, leading fragments on the West and a bright, trailing one on the East, with what looks like a cloud of debris between them. While C/2025 K1 ATLAS is significantly fading, it remain a truly intriguing target.
We will continue monitoring this comet.
