A goodbye glimpse of Comet A3

Comet A3 Tsuchinshan-ATLAS made a great evening appearance for us in October, becoming visible with the eye alone. The comet is now headed away from Earth, but the Virtual Telescope Project is letting you get a goodbye glimpse this Christmas. Join in at 17:00 UTC (11:00 a.m. CST) on December 23, 2024, at the Virtual Telescope site to watch a live view of the departing comet.

And you can see the comet in the pics below. People around the globe captured fantastic images of Comet A3 just after sunset. Check out some of the great images from our EarthSky community here. And see even more pics in this video.

Comet A3 in the evening sky

Starry sky. Comet with a long, thin tail to the right. A wide, glowing, cloudy band of stars to the left.
View at EarthSky Community Photos. | Dean Balosie from Flamingo, Florida, shared this image of Comet A3 he captured on October 21, 2024. He wrote: “First clear night in months, I was in luck with about a 2 hour window before the clouds rolled back in. Very grateful I got to witness this comet before it leaves us. I think it looked spectacular parting the black sky!” Thank you, Dean.
A seacoast with tall pointy rocks. Pink-to-blue sky. The comet, and a cloudy band of stars.
View at EarthSky Community Photos. | Abhijit Patil from San Mateo, California, captured the comet, the Milky Way and Venus on October 19, 2024, and wrote: “As an astrophotographer, this is the first time I am capturing a comet with the Milky Way. I am sure this is the case with many night owls like me. I would like to term this as a rare occurrence and a very beautiful one. Earlier I have shot Jupiter along the MW but photographing Venus and the Comet was truly a surreal experience.” Thank you!

View at EarthSky Community Photos. | Petr Horálek from Spišská Belá, Slovakia, captured this image of Comet A3 on October 16, 2024. Pietr wrote: “Today the moon appears in the sky as the brightest full moon of the year since it is a perigee moon. However, Comet C/2023 A3 Tsuchinshan-ATLAS made another record as it was visible despite the bright moon. In the highest visible summit in the image, right from the comet’s head, you can spot a small shining pearl, the Lomnicky Stit Observatory, where Czechoslovakian astronomers in 50s of last century discovered several other comets (including 45P/Honda-Mrkos-Pajdusakova).” Thank you, Petr!
