Northern Lights – Autumn Equinox
The coming of the Autumn Equinox 2022 is on Friday 23 September. It brings the start of the astronomical autumn in the northern hemisphere, a season known for red and yellow colors in the forest. But did you know it can also color the night sky green? As the month continues you’ll slowly start to notice colder weather and shorter days. But what exactly is the Earth doing to cause these seasonal changes? It’s all in our planets tilt.
Our planet turns around the sun at a slight angle of about 23.5 degrees . This little lean is responsible for all of our seasons. So when the Northern Hemisphere is tilted away from the sun it’s winter up here. But it’s summer for everyone down in the Southern Hemisphere. The Spring equinox is a transitional period when the Northern Hemisphere begins to lean towards the sun, ushering in spring.
One strange side effect of the equinox is a dramatically increased likelihood of Northern Lights – Aurora Borealis. The magnetic storms that flare like ghostly fire in our atmosphere. For Northern Lights to happen, the Earth’s magnetic field and the magnetic field of the solar wind have to connect. Earth’s tilt at the equinoxes appears to orient the planet’s magnetic field in a position that’s ideal for the solar wind to create these illuminating electron collisions.
To increase your change to see this natural phenomena we offer Northern Lights tours from September to April from Luleå in the most northern part of Sweden. Both by car and a more active variant by snowshoes. Together with an experienced guide you will go on a hunt for searching the magical Northern Lights and learn more about this natural wonder.
