On Tuesday, there will be a solar eclipse in Norway, which will at most cover 73 percent of the solar disk. Last year there was a solar eclipse in this country, but this time it will be bigger. The last time there was a total solar eclipse in Norway was in 2015, and it took place on Svalbard. Astrophysicist Tor Einar Aslesen of the Norwegian Astronomical Society was himself present during that solar eclipse. This time he will stay at home in Eastern Norway. – It is a relatively large part of the sun that will be covered throughout Norway. But Longyearbyen can only barely see it this time.

A total eclipse occurs when the sun is completely covered by the moon. The intensely bright sun disc is replaced by the dark invisible moon disc. The sun’s corona, which is otherwise far too faint to be seen, now becomes visible as a luminous ring. Totality is only visible from a very narrow strip on the earth’s surface. An annular eclipse occurs when the Sun and Moon are exactly aligned as seen from Earth, but the Moon is too far from Earth to cover the entire solar disk. The sun will then be seen as a very bright ring around the moon. A partial eclipse occurs when the sun and moon are not exactly aligned. The moon will then only partially shade the sun. This is what can be seen during all three other types of eclipses in locations off the central line. This can also occur even if the central line does not hit the earth at all. Source: Wikipedia – Don’t look at the sun without protection Although there won’t be a total solar eclipse this time, the conditions in Norway are basically good, he says. – Eastern Finnmark receives the greatest coverage of the sun. In Kirkenes, there will be more than 62 per cent of the sun. It is also quite good in Tromsø, which gets 56 percent coverage. – For Oslo’s part, there will be around 40 per cent coverage in the middle of the day, and roughly the same in Western Norway. You can read about the weather conditions further down in the case. Aslesen goes on to say that there are currently sunspots, and these can be seen with a good camera, for example. The time at which the solar eclipse is greatest varies slightly from place to place. It will be greatest in Siberia, but there will not be a total eclipse there either.

Neither with eyes, with a camera or telescope. You must have a filter. Solar eclipse filters are the best, regardless of field of application. – And you shouldn’t wear ordinary sunglasses either, he adds. Looking at the sun during a solar eclipse is no more dangerous than otherwise, but you should generally not open your eyes to the sun over time. The reason is ultraviolet rays, which can be harmful to the eyes. – Solar eclipse glasses can be used, but you should check that they are approved. If you have a telescope, you can see that the moon has a slightly jagged edge when it passes in front of the sun, because of the mountains and craters there, he explains. People went completely “bananas” when they experienced a total solar eclipse on Svalbard in 2015. Make your own projector If you don’t have suitable glasses or filters lying around, Aslesen says that you can easily make a smart projector from a simple cardboard sheet. – Then you make a small hole in the cardboard, aim it at the sun, and then you actually get a small picture of the solar eclipse on the wall. It is an optical phenomenon, he explains. The hole must be very small, no bigger than the tip of a ballpoint pen, says the astrophysicist. He believes the solar eclipse is something you should catch if you get the chance. – It makes you feel like part of the cosmos. Watching one globe go before another is always fascinating. If you want to look directly at the sun, you should wear protective glasses.

So how are the conditions? – It is probably Nordmøre, Trøndelag and parts of northern Norway that will get the best conditions as it looks now, says meteorologist Trond Robertsen. Regarding the latter, he says that it is the area from Bodø and north to the Nordkapp that has the best forecasts. Western Norway and Eastern Norway do not have equally good prospects. This is what a total solar eclipse looks like from space. But whether it becomes equally visible from the ground depends on the weather. Photo: CNES/JEAN-PIERRE HAIGNERE / AFP – Western Norway south of Stad, as well as Sunnmøre and Romsdal, can probably expect quite a lot of rain, according to the forecasts. There is also some gray weather and rain in Southern and Eastern Norway. But don’t give up hope, is the meteorologist’s advice. The two low pressure systems that threaten the possibilities may change direction. And there can always be holes in the cloud cover. – We cannot predict that, says Robertsen.
