Comet C/2023 A3 (Tsuchinshan-ATLAS) is the comet on everyone’s lips at the moment, and over the past weekend photographers and comet-chasers were out in force capturing amazing images of it.
For those of us who’ve been eagerly awaiting the appearance of Comet A3 all year, October 2024 is the month when we’ll finally get to see whether it becomes a glorious naked-eye object.
And over the weekend of 27-29 September, many comet-chasers back on Earth were out catching a glimpse of the comet and photographing it.
Comet C/2023 reached perihelion on 27 September, which is the point in its orbit when it’s closest to the Sun.
The comet is now very close to the Sun in the sky, but will reemerge and become easier to observe mid-October, its separation from the Sun increasing as the month goes on.

The comet’s closest approach to Earth occurs on 12 October, and the days following this date will be some of our best chances to see it.
While we wait for that time, we’re continuing to receive amazing images of Comet C/2023 A3 Tsuchinshan-ATLAS from photographers around the world.
Below is a gallery of some of the best we’ve received so far.
If you’ve been out and captured an image of comet A3, don’t forget to send us your images, and we’ll include our favourites in this very gallery.

The comet shows a certain greenish hue in this image obtained remotely from the southern hemisphere, from where it will still be observable for a few more weeks before it plunges into the twilight and won’t be observable again until October.”

Comet C/2023 A3 (Tsuchinshan-ATLAS) captured by José J. Chambó on 2 May 2024 from Vallés, Valencia, Spain. Equipment: Atik 383L camera, TS-Photon 8-inch f/3.6, Sky-Watcher EQ6R-Pro mount. Exposure” 47 min. (L=44×60 bin1 RGB=1×60 bin2)José says: Comet C/2023 A3 shows a brightness that has remained at magnitude 10.5, the same as I recorded three weeks ago. However, the angular length of its tail has doubled, from 2.5′ to 5′, probably due to the increase in the phase angle, which implies that we now observe it more from the side. In the image, the comet’s tail can be clearly seen extending to the left, with a bright and well-defined coma. This pause in the increase of brightness is common in comets visiting the inner Solar System for the first time. Hopefully, it will soon resume its brightening trend.”Credit: José J.
