Nature’s beautiful offering and gift – not forced – an amazing grace of natural living love.
Let it BE y/our LIFE…

Aurorae are the most visible on northern and southern Polar Regions due to the form of the Earth’s magnetic field. In Finland, aurora borealis can be most often viewed in the northernmost Lapland, approximately on 200 nights a year, whereas in southern Finland the phenomenon is rare with about two dozen sightings annually. In 2000 and 2001, a very powerful aurora borealis storm occurred, when bright bands of aurora borealis were seen on the northern hemisphere all the way down to southern Europe. Most commonly, aurora borealis can be seen as steady arch but many kinds of forms can be seen from time to time.
Electric particles from the sun, such as protons and electrons, are carried by the solar wind to the Earth’s magnetic field that reaches as far as 100 000 km above the atmosphere. Due to the influence of the solar wind, this field, i.e. magnetosphere, stretches forming a tale of millions of kilometres on the night side of the Earth. Part of the electric particles drift to the Earth’s magnetic field to form the so-called Van Allen zone. Part of the particles are stored in the tale of the magnetic field and carried from there along force currents to the proximity of the poles of the Earth. These particles are pushed into the atmosphere of the Earth, colliding with the molecules of different matter 80 to 300 km above the ground and exciting the atoms. When the excitation is released, the extra energy is released as light. Depending on the variety of the excited atom, the released light can have different wavelengths that are visible to the eye in different colours.
Aurora borealis cannot be seen at all times. The best time of the day is during the magnetic midnight, which occurs approximately an hour before the actual midnight. The difference is caused by the 11º-difference between the North Pole on top of the axis of the Earth and the magnetic North Pole. According to observers, the aurora borealis is the most commonly seen during Equinoxes, but also on other bright winter nights viewing is possible.
