Comet Tsuchinshan-ATLAS is still visible in the night sky, but not for long
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.
