Kohinahavainnoilla

Kohinahavainnoilla refers to observations of the aurora borealis, commonly known as the Northern Lights, in Finnish. This phenomenon is a natural light display in the Earth's sky, predominantly seen in high-latitude regions. The aurora is caused by disturbances in the magnetosphere caused by solar wind. These disturbances accelerate charged particles in the solar wind, which then collide with atoms in the Earth's upper atmosphere. These collisions excite the atoms, causing them to emit light. The most common colors observed are green and pink, but other colors such as red, yellow, blue, and violet can also be seen.

In Finland, the best conditions for viewing kohinahavainnoilla are during the dark winter months, typically from September to March. Clear skies and minimal light pollution are essential for optimal viewing. Popular locations for aurora hunting in Finland include Lapland, which is situated within the Arctic Circle, offering a high probability of witnessing the display. Towns like Rovaniemi, Inari, and Kilpisjärvi are well-known destinations for aurora tourism. Various organized tours and activities are available to help visitors find the best viewing spots and learn more about the science behind the aurora. The intensity and frequency of the aurora are influenced by the solar cycle, with periods of higher solar activity leading to more spectacular displays.
