The case in summary: Comet C/2023 A3 Tsuchinshan-ATLAS, which was last seen 80,000 years ago, will be visible to the naked eye this weekend and in the month ahead. The comet is very bright and is expected to be the brightest for many years. The comet was visible in the southern hemisphere in early October with a tail 30 times larger than the full moon. The comet will be visible to us from Friday 11 October, and it is best to look to the west where the sun sets. The chances of seeing the comet are good in the East, Southern and inner parts of Troms on Friday evening, while the weather will be finer in Troms and Finnmark and in inner Nordland on Saturday evening. The summary is made by an AI service from OpenAI. The content is quality assured by news’s journalists before publication. – This is very large because this comet is very bright. There are many comets in the sky all the time, but this one will be the strongest for many years. Joakim Martin in the association Deep Sky Exploration.

The comet, which has been given the sounding name C/2023 A3 Tsuchinshan-Atlas, was last seen 80,000 years ago, in the Neanderthal era, and will most likely not swing by the earth again until 80,000 new years have passed, according to the astronomers. – Many people probably remember the comet Hale-Bopp from 1997, it was very powerful. We know this comet is even stronger, so it will be exciting to see how bright it will be, says Martin. Note the tail At the beginning of October, the comet was visible in the southern hemisphere in the morning, with a tail that extended around 15 degrees across the sky as seen from Earth. By comparison, the full moon is 0.5 degrees in the night sky, so the tail of the comet was 30 times as large as the full moon. The tail of the comet is much larger than the full moon. Photo: Per-Kåre Sandbakk / news – In the southern hemisphere it had a long, beautiful line of a tail. In some places the tail was also blue in colour. Now the tail is affected by the sun, so when we first get to see him we don’t know how spectacular the tail will be. It can be huge, says Martin. Dirty snowballs Alexander Sandtorv is all of Norway’s National Chemist. He thinks comets are pretty cool, because they have been given a cute nickname in the scientific community. Chemist Alexander Sandtorv. Photo: Emil W. Breistein – They are called dirty snowballs, and I think that’s so cute. Comets consist of gas, snow, ice and water frozen into ice. There are several types of comets that vary in size from around 100 meters to 30 km. Comets’ journey through the universe varies from a few years to hundreds of thousands of years. – Many of them come past our outermost planet, Neptune, and rush into the solar system. Then they go around the sun, and then they travel back again. They are like torments in the universe, only that they take a long time, laughs Sandtorv. How to see it best The comet will first be visible to us on Friday 11 October. Then the comet descends an hour and a quarter after sunset. Look to the west, then you can see the comet best. Photo: Håkon Mosvold Larsen / NTB – It’s just a matter of gearing up. Look to the west where the sun sets. It is wise to go somewhere where it is as dark as possible, and where there are no street lights, buildings or mountains that disturb the view, says Joakim Martin. On Monday 14 October, the comet can be observed for two and a half hours after the sun has set. But that of course provided that there is sun and no clouds. Meteorologist Charalampos Sarchosidis.

On Saturday evening, the weather will be fine in Troms and Finnmark and in the interior of Nordland. On Sunday evening, it is Rogaland, Hordaland and parts of Southern Norway that get away with the best weather. – On Monday evening, when the comet appears to be at its furthest, it will clear up again on Austlandet and the coast of Western Norway. In addition, it will be great in Aust-Finnmark and on the Finnmarksvidda, says the meteorologist. Hi Thank you for reading.
