Citizen Astronomers with the Unistellar & SETI Institute Network have been watching #CometA3 since mid-2023 to help astronomers track and predict its activity. Cometary Activity program lead Dr. Ariel Graykowski used their data to create models that suggested Comet A3 would shine as brightly as the North Star when it approached. But it did much more than that! At its most luminous, Comet A3 reached a magnitude of -5… 25 times brighter than the brightest star, Sirius!

#PPOD: Comet C/2023 A3 (Tsuchinshan-ATLAS) passes over NASA’s Michoud Assembly Facility in New Orleans in this Oct. 13, 2024, image. This comet comes from the Oort Cloud, far beyond Pluto and the most distant edges of the Kuiper Belt. Though Comet C/2023 A3 will be visible through early November, the best time to observe is between now and Oct. 24. Credit: NASA/Eric Bordelon

Sky is finally looking clear enough to go C/2023 A3 spotting tonight 🤞🏻

Last night, I managed to finally have a view of Comet A3 (Tsuchinshan-ATLAS). ☄️

There was too much city light to see it with the naked eye, but easy enough to take a photo of. I'm in Central London after so was quite happy to be able to still see it.

In fact, I caught it my first shot of the evening, without realising it!

I then later took some more close up shots, but I kindof like the first one best.

Struggled some more with photographing the comet... can now be seen from my backyard... it's huge but also eerily faint and wispy

A photo of Comet A3 this evening. It was impossible to see with the naked eye, but pointing my camera in the general direction of the comet paid off quickly for me. I used a 6 second exposure to capture as much detail as possible. #cometA3 #comet

Started on the roof of my house, then the front yard, best few is from the corner of the street.
#CometA3. Pixel 8 Pro camera.
See ya in 80,000 years buddy.

And keeping up with my theme of astronomical images being photobombed by aeroplanes.... #astrophotography 🔭 I love that the water was so calm this evening that the aeroplanes lights are even reflected in the sea! #cometA3

The A3 comet will soon be visible in the night sky, but the clock is ticking on its ideal viewing time. Known officially as Comet Tsuchinshan-ATLAS, the celestial object reached a state known as its "perihelion" on Sept. 27, meaning the point at which it's closest to the sun. It'll reach the point closest to Earth in mid-October, and until then, eager stargazers will have a few opportunities to try to get a look at it.
