How to See Comet C/2023 A3 (Tsuchinshan-ATLAS) Tonight
Hello fellow star gazers! 🌌 As an amateur astronomer and night sky enthusiast, I’m beyond excited to share that Comet C/2023 A3 (Tsuchinshan-ATLAS)—the most talked-about comet of 2024—is already gracing our skies! Right now, observers in the Southern Hemisphere are enjoying its brilliance, and it won’t be long before us in the Northern Hemisphere can join in on the excitement. So grab your binoculars and stargazing apps, because tonight could be your chance to catch this spectacular cosmic visitor!
What Makes C/2023 A3 (Tsuchinshan-ATLAS) So Special?
Let’s dive into why this comet is capturing the imagination of so many. To begin with, C/2023 A3 is expected to be exceptionally bright. While its future brightness is still a work in progress (thanks to the unpredictable nature of comets), most sources agree that we might see it with the naked eye. If we’re lucky, it could even outshine the iconic Comet NEOWISE from the summer of 2020. Hasn’t it been a while since we’ve seen a comet this remarkable?
Additionally, C/2023 A3 is anticipated to develop an awe-inspiring cometary tail. After it swings past the Sun at a distance similar to Mercury’s orbit, the heat will cause its icy core to evaporate dramatically, leading to the formation of an impressive tail made of dust and gas. If history teaches us anything, it’s that comets heated by the Sun often exhibit the most striking tails.
For those of us in the Northern Hemisphere, this is particularly exciting! The last time we saw such a bright comet visible from northern latitudes was during the 1997 spectacle of Comet Hale-Bopp.

Is C/2023 A3 (Tsuchinshan-ATLAS) Visible Now?
Good news for those in the Southern Hemisphere! Currently, C/2023 A3 is visible in the mornings, appearing low in the eastern sky just before sunrise. With a current magnitude of about 2.6, it’s brighter than anticipated and continues to brighten daily.
If you’re in the Northern Hemisphere, the comet is a bit more challenging to see due to the Sun’s brightness; however, it’ll start becoming visible in early October.
Visibility Forecast: What Lies Ahead
Let’s paint a picture of what to expect in the coming weeks:
- September 27 – October 2: This is when the comet reaches perihelion, appearing in the early morning sky.
- October 10-12: The comet will become more visible in the evening, shortly after sunset, in the constellation Virgo. These dates are critical as it will be at its brightest around October 12, making it easier to see with the naked eye.
- October 15-31: The comet will fade but will still be visible with binoculars and telescopes.
The best time for observation is likely from October 10-12, just after sunset. So get out there—don’t miss the chance to witness this celestial wonder!
Tips for Photographing C/2023 A3 (Tsuchinshan-ATLAS)
If you’re an aspiring astrophotographer like me and you want to capture this comet on film, consider following these steps:
- Gear up: Have a DSLR or mirrorless camera, sturdy tripod, and a wide-angle or zoom lens ready.
- Camera Settings: Use manual mode with an ISO setting between 400 and 800, and a wide aperture of f/2.8 to f/4 to let in enough light.
- Location Matters: Pick a dark spot far from city lights. Star Walk 2 can help you find the comet’s exact location.
- Take Multiple Shots: For detailed images, take a series of photographs and use software like DeepSkyStacker for stacking.
- Post-processing: Tools like Photoshop will help refine your final image.
The Journey Ahead: What’s Next for C/2023 A3?
As we all wait in eager anticipation, it’s worth noting that C/2023 A3 (Tsuchinshan-ATLAS) is on a long journey. It completes one orbit around the Sun roughly every 80,660 years! If you’re wondering what the future holds, after its approach in October, this comet will slowly fade from view and won’t return until the year 26,000.
To Wrap Up
Excitement is in the air as we prepare to welcome this spectacular comet! C/2023 A3 (Tsuchinshan-ATLAS) is already putting on a show for observers in the Southern Hemisphere, and soon it will light up the skies for us in the North. As we gear up for this enchanting astronomical event, don’t forget to download the Star Walk 2 app to help you navigate the night sky like a pro.
Let’s get ready to bask in the glow of C/2023 A3—happy stargazing, everyone! 🌠
