As the earth passes through the trail of the remains of a comet, the burning of meteorites in the atmosphere will result in the sparkling display in the night sky over Sweden.

The phenomenon, known as the Perseids, occurs in August every year, when the earth moves through the solar orbit of the Swift-Tuttle comet.

The meteor shower – actually meteorites and dust burning up on entering the earth’s atmosphere – can be up to 90 shooting stars per hour.

The best views of the Perseids in Sweden will be in the south of the country, according to website Populär Astronomi. While visibility will be better in the countryside, the meteor shower will also be observable from towns and cities.

Between 1am and 2am, when the sky is darkest, will be the best time to spot the cosmic event.

Weather could present a problem for spectators in Sweden, however, with cloud cover in many parts of the country forecast by meteorological institute SMHI.

Large areas between Östersund and Luleå, as well as in western Skåne, are forecast to have clear skies.

Although the meteor shower is likely to be most easy to spot from earth on Sunday night, it has been visible since the end of July and will remain so for a further two weeks.

The Perseids take their name from the constellation Perseus, the constellation from which they are thought to have originated.

NORTHERN LIGHTS

Why the northern lights might be visible in more of Norway than usual

Current atmospheric conditions mean there's a good chance the aurora borealis will be visible across much more of Norway than normal on Friday.

Normally, the northern lights are only visible in northern Norway, typically between April and September.

According to the Geophysical Institute of Alaska the KP index, which is a system of measuring aurora strength, will reach Kp 5 out of a possible 9.

Anything Kp 5 and above is classed as a geomagnetic storm. This means you will be able to see the green lady a lot further south than you usually would.

The reason for this high forecast is “corona holes” (no relation to the pandemic). These are holes in the Sun’s atmosphere, where solar wind is thrown out at high speeds.

The northern lights occur when the protons and electrons from solar wind hit the particles in the Earths atmosphere and release energy.  

“You can see it down towards eastern Norway as an arc on the horizon, while in central Norway and in Trøndelag it will be right over your head.” Pål Brekke, head of space research at the Norwegian Space Center, told newspaper VG.

While there will be strong northern lights activity over large parts of the country, it does not necessarily mean that everyone will get to see it.

“It doesn’t look too promising in Nordland and Troms”, state meteorologist, Sjur Wergerland told VG.

However, he also added that the forecast looks much better further south.

Even then though there is no guarantee you will see the northern lights, according to Brekke.

“It is not certain that the northern lights will move as far south as we think, but I recommend people to follow forecasts on websites to stay up to date,” he said.

In order to see the northern lights, the weather will also have to be on your side. Clear skies are best and going to areas with no or low light pollution is important too.

If you are lucky enough to see the lights make sure you don’t wave at them. Doing so will cause the lights to lift you up and take you away according to Norwegian folklore.
