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.

A rare celestial event is lighting up the night sky this month as Comet Tsuchinshan-Atlas makes its closest approach to Earth for the first time in roughly 80,000 years.

October will feature yet another rare celestial treat. Look to the night sky to see the biggest supermoon of the year along with Comet Tsuchinshan-ATLAS.
