If the conditions are right, comets can leave debris trails that cause meteor showers if Earth’s orbit encounters their path, such as the October Orionids, which are particles from the famous Halley’s comet.

The next meteor shower, the Southern Taurids, is expected to peak on the night of November 4 into the early morning of November 5 and also has a comet for a parent body called Comet Encke.

"However, any debris from C/2023 Tsuchinshan–ATLAS or C/2024 S1 will not pass near enough to Earth to produce a meteor shower," Cooke said.

"How often comets are visible in our skies is variable, with some years offering up a handful of the icy bodies that sky-gazers can spot and others not so fruitful," Battams said.

“Historically, comets have always been a source of fascination to people, in part due to the fact that they are such infrequent occurrences,” he added.

“I’m sure back in pre-industrial times when light pollution was no concern, some of the comets that people saw must have been equally awe-inspiring and terrifying!”

THE SUN JUST SWALLOWED A COMET: The solar system has one less comet. Comet ATLAS (C/2024 S1) melted away today when it passed within 0.008 AU of the sun. Coronagraphs onboard the Solar and Heliospheric Observatory witnessed the final moments.

In the movie, an opaque disk covers the sun, blocking its glare to produce an artificial eclipse. This allowed SOHO's digital cameras to see the comet only 550,000 km from the surface of the sun.

Comet ATLAS is a Kreutz sungrazer, a family of comets which are fragments from the breakup of a single giant comet ~1000 years ago. SOHO has discovered thousands of them, almost all disintegrating near the sun.

The end of Comet ATLAS is a disapointment. When it first appeared in September, an outburst brightened the comet, making it appear larger than average Kreutz fragments. Many astronomers hoped it would survive the sun and put on a magnificent display like Kreutz Comet Ikeya-Seki did in 1965. Maybe next time :)

Five Bright Comets from SOHO Image Compilation Credit: Tunc Tezel (TWAN)

Explanation: Five bright comets are compared in these panels, recorded by a coronograph on board the long-lived, sun-staring SOHO spacecraft. Arranged chronologically all are recognizable by their tails streaming away from the Sun at the center of each field of view, where a direct view of the overwhelmingly bright Sun is blocked by the coronagraph's occulting disk. Each comet was memorable for earthbound skygazers, starting at top left with Comet McNaught, the 21st century's brightest comet (so far). C/2023 A3 Tsuchinshan-Atlas, approaching its perihelion with the active Sun at bottom center, has most recently grabbed the attention of comet watchers around the globe. By the end of October 2024, the blank 6th panel may be filled with bright sungrazer comet C/2024 S1 Atlas. ... or not.

[boccher]

now that c/2023 A3 tsuchinshan-atlas is fading from visibility let's look at what c/2024 S1 atlas is doing

over the past week there been reports that the comet's nucleus was becoming diffuse and elongated, possibly disintegrating, which got covered by some news sites. but since then most observations have found a tight nucleus again. so a disintegration event is not solidly confirmed

observations from yesterday and today show that the comet is undergoing a dramatic outburst, brightening by 2-3 magnitudes. this increase activity could also indicate fragmentation, but in lieu of other convincing evidence, it could just be highly reactive to the solar wind which would be a positive indicator for its future brightness

since this comet is unique as a kreutz sungrazer and is exhibiting such erratic behaviour, we can't really predict what's going to happen to it or how bright it will get as it crosses the sun in 10 days. the most we can do is compare it to its analogue c/2011 W3 lovejoy. if it acts the same way (partially or totally disintegrating after it passes the sun) then there's a possibility that it becomes bright and visible. it's also possible that it doesn't become visible at all. but we cant assign any numerical probability to any outcome, we can only wait and see

2024 April 17

The totally eclipsed Sun from 2024 April 8 is shown in the center. Two comets and two planets are also visible, and labeled as 12P, Mercury, SOHO-5008, and Venus. The two comets are shown in expanded form at the top in two inset images.

Please see the explanation for more detailed information.

Total Eclipse and Comets

Image Credit & Copyright: Lin Zixuan (Tsinghua U.)

Explanation: Not one, but two comets appeared near the Sun during last week's total solar eclipse. The expected comet was Comet 12P/Pons-Brooks, but it was disappointingly dimmer than many had hoped. However, relatively unknown Comet SOHO-5008 also appeared in long duration camera exposures. This comet was the 5008th comet identified on images taken by ESA & NASA's Sun-orbiting SOHO spacecraft. Likely much smaller, Comet SOHO-5008 was a sungrazer which disintegrated within hours as it passed too near the Sun. The featured image is not only unusual for capturing two comets during an eclipse, but one of the rare times that a sungrazing comet has been photographed from the Earth's surface. Also visible in the image is the sprawling corona of our Sun and the planets Mercury (left) and Venus (right). Of these planets and comets, only Venus was easily visible to millions of people in the dark shadow of the Moon that crossed North America on April 8.

Hello! There's this one fic i read some years ago i can't manage to find right now, it would be SO great if you guys could help me 🥲 So basically it's about Draco cursing his family name (Malfoy) because he wants to feel pain each time someone says it to it. So i think the fic starts with Draco working as a cafe barista in the human world and harry walks into the shop and calls him Malfoy, so the curse is kinda unlocked and Draco gets sick so he has to stay under surveillance in Harry's house

The Sungrazing Comet by Snappy_Snippets, SzmaragDrac (35k, E)

[alascene]

They just found a fresh kreutz sungrazer comet, which are fragments of a giant ancient comet that gets really close to the sun at their perihelion. Not only are we getting Tsuchinshan mid October, we'll also get this new boy which could potentially outshine the moon during the day as it gets close to the sun. COMET SEASON BABYYYYY

[spacenutspod]

A surprise appearance of a new comet made the April 8th total solar eclipse all the more memorable. Any dedicated ‘umbraphile’ will tell you: no two eclipses are exactly the same. Weather, solar activity, and the just plain expeditionary nature of reaching and standing in the shadow of the Moon for those brief moments during totality assures a unique experience, every time out. The same can be said for catching a brief glimpse of what’s going on near the Sun, from prominences and the pearly white corona to the configuration of bright planets… and just maybe, a new comet. The Discovery While many planned to try and spy periodic Comet 12P Pons-Brooks during totality, astronomer Karl Battams at the U.S. Naval Observatory alerted us to another possibility. A new sungrazing comet, spotted just hours prior. The Kreutz family comet was seen by Worachate Boonplod in the field of view of the joint NASA/ESA Solar Heliospheric Observatory’s (SOHO) LASCO C3 and C2 imagers. These are equipped with Sun-covering coronagraphs that allow it to see the near solar environment. The mission was launched over a quarter of a century ago in 1995. SOHO was deployed to the sunward L1 Earth-Sun Lagrange point nearly a million miles distant. SOHO has since proven itself to be a crucial workhorse in solar heliophysics. Doomed SOHO-5008 (lower left). Credit: NASA/ESA/SOHO The comet soon received the formal designation of SOHO-5008. That’s right: SOHO has led to the discovery of over 5,000 comets in its career. Most of these discoveries were thanks to the efforts of dedicated online sleuths, scouring recent LASCO images. At the time, the doom’d comet was a faint object, located only a few degrees from the Sun. The icy interloper was a tough target to nab during the fleeting minutes of totality, but at least two dedicated astrophotographers managed to catch it. Lin Zixuan saw it imaging from northern New Hampshire. Petr Horálek from the Institute of Physics in Opava Czechia (Czech Republic) was imaging from Mexico as he caught the object. Like so many other sungrazers, the comet met its demise shortly after discovery (less than 12 hours, in fact), like a sundiving spaceship at a Disaster Area concert right out of Douglas Adam’s Hitchhiker’s Guide to the Galaxy. A Brief History of Sungrazers This sort of SOHO versus comet, versus eclipse discovery has only occurred twice: once in 2008 and again in 2020). SOHO wasn’t designed per se to find comets, but its prolific nature as a comet hunter has become an essential part of the legacy of the mission. SOHO has defined whole new families of Kreutz, Marsden and Kracht sungrazing comets. And to think, prior to the mission, only sixteen sungrazing comets were even known of. One similar case was the Great Comet of 1948, which was also discovered by stunned observers during a total solar eclipse. Another was C/1965 Ikeya-Seki, which went on to become one of the truly great comets of the 20th century. More recently, C/2011 W3 Lovejoy surprised everyone by surviving its perihelion passage 140,000 kilometers from the surface of the Sun. Just one year later, however, 2012 S1 ISON didn’t. It was a thrilling celestial spectacle, with an added treat. The post There Was a Doomed Comet Near the Sun During the Eclipse appeared first on Universe Today.

The 'Halloween Comet' Appears to Be Disintegrating in Space

Michelle Starr for ScienceAlert:

A comet that was predicted to become bright enough to see with the naked eye at Halloween seems to be disintegrating right before our eyes.

It's called C/2024 S1, discovered on September 27, a rare Kreutz sungrazer comet whose trajectory is due to bring it within just 1.2 million kilometers (750,000 miles) of the Sun on 28 October 2024.

Alas, it seems that C/2024 S1 has, after billions of years, disintegrated. Images of the object taken over the course of October show it brightening with outburst activity before dimming, its nucleus appearing to vanish, leaving behind a tail of dust and gas, and, maybe, a cloud of cometary debris.

I'm also disintegrating, so relatable
