Unlike our quasi-moon 2025 PN7, this one is actually bound to Earth, for now.
Its orbit is pure chaos. Enjoy it while it lasts. It’ll probably be demoted to space junk.

It was observed through the LASCO-C3 coronagraph aboard the SOHO solar space telescope, and I think it went largely unnoticed.

For this one I used my mono camera with red, green and blue filters to capture colour data, which I added to the main mono image to create an LRGB colour image.
Scope was a 550mm focal length Esprit 100.

C/1639 U1
1639 Oct 25: Seen only over three days and recorded from Korea, China and Italy. Close perigee on Oct 26 at only 0.08 au while exhibiting a "fluffy shape"! The comet was not very bright but rather large, typical for comets close to Earth.
