The coma and long tail of comet Tsuchinshan-ATLAS, also called C/2023 A3 (Tsuchinshan–ATLAS), is currently shining at magnitude +0.5. That's well within the grasp of the human eye. It's likely now past its best, but only just, and will likely remain a naked-eye object after sunset in the west until, and possibly through, the weekend.

The ancient comet—dubbed the "comet of the century"—returns to the inner solar system only once every 80,000 years.

The best comet of the year is starting to fade in brightness, but it’s still an easy naked-eye object in the evening sky.
