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!

IN THE SKY THIS WEEK - Comet A3 continues to shrink and fade as it recedes into the inky murk, Venus is in conjunction with orange Antares low in twilight on Friday, Halloween evening is moonless, but it offers three bright planets. Venus is very low and after dark, Saturn is the brightest little dot high toward the south-southeast. By about 10, Jupiter has climbed up to dominate the east. If you're very lucky you may catch some fireballs from the Taurids.

#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

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

IN THE SKY THIS UPCOMING WEEK: Comet A3 fades back into the abyss but before the Moon rises, you may still be able to catch dim naked eye glimpses of the dirty ice ball. Cameras, telescopes and binoculars will be best now. Stay up late for the Orionid meteor shower, but the bright Moon will quash all but the brightest. Standing nearly 30° high in the southeast an hour after sunset, Saturn is the brightest point of light in this region of the sky, Mars is brightening, and the Moon has a cuddle with bright Jupiter Monday morning.

Expect a clear and cool night for the WAS Weekly Wednesday Star Party this evening 10/16. We are going to open early at 7 pm tonight so you can see Comet C/2023 A3. We will have the telescopes looking at the comet but it does look best with binoculars and the naked eye. Just becoming visible, it's high up at 20 degrees and in the West. The nearly Full Hunter's Supermoon - the biggest of the year - will light up the night. https://was-ct.org/events/the-was-weekly-wednesday-star-party/

Started on the roof of my house, then the front yard, best few is from the corner of the street.

See ya in 80,000 years buddy. -
Comet A3 is just spectacular now and visible about 45 minutes after sunset. It has a massive tail and very easy to see naked eye. Shannon Calvert caught it setting above the observatory tonight 10/14. It is quickly getting higher every night.You can actually see the anti-tail in front of the comet. They appear when Earth passes through a comet's orbital plane.

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

COMET TSUCHINSHAN-ATLAS HAS AN 'ANTI-TAIL': Today is a special day for Comet Tsuchinshan-ATLAS. Earth is passing through the comet's orbital plane, and this is causing the comet to sprout a rare 'anti-tail.' It's a gorgeous sight in the evening sky, so bright that you can photograph it using ordinary smartphones. From many locations around the planet the comet is a naked eye object but looks really great through cameras and binoculars. https://Spaceweather.com for more.

October '24 has already been a month many of us will never forget, but it's about to get even better with the arrival of Comet A3. Appearing just after sunset, the comet will quickly rise moving away from the glare of the sun and glide to the South as it retreats back into the outer solar system. However, over the next week or so, we could be rewarded with some gorgeous naked eye and binocular views. Here's how to see C/2023 A3: https://skyandtelescope.org/astronomy-news/get-ready-for-comet-tsuchinshan-atlas-the-best-is-yet-to-come

SEVERE GEOMAGNETIC STORM WATCH: An X-class solar flare on Oct. 8th hurled a fast-moving CME directly toward Earth. NOAA and NASA models agree that it could arrive as early as Oct. 10th, with NOAA forecasters warning of a possibly severe geomagnetic storm. This movie from SOHO shows not only the CME, but also Comet Tsuchinshan-ATLAS passing close to the sun. The CME will hit the comet before it hits Earth and could rip off the comet's tail. https://Spaceweather.com

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. -
