Many visitors to Finland come with hopes of seeing the Finland Northern Lights, which is a natural phenomenon that is also known as the Finland Aurora Borealis. The best place to see the Northern Lights in Finland is in the northern Lapland region, which is almost entirely located within the realm of the Arctic Circle. During the dark winter months here, when the sun rarely peaks its head over the horizon, you can expect to see the Finland Northern Lights with regularity, and other peak seasons include February through March and September through October. If you have never seen the Northern Lights wherever they commonly occur in the world, then chances are good that you will be amazed the first time that you lay eyes on them. Swirling shades of blue, green, and red are most common when it comes to the Finland Northern Lights, and as one might expect, clear nights are best for viewing them.
For those who are wondering what causes the Northern Lights in Finland, solar flares are largely responsible. These flares effectively cause solar winds and solar storms, which create lingering atmospheric particles or matter upon colliding with the earth’s atmosphere. As such, scientists can often accurately predict when the best times are for viewing the Northern Lights in Finland by keeping an eye out for solar flares. As mentioned, Lapland is the best place to see the Finland Aurora Borealis, with the Kilpisjarvi area offering the most abundant opportunities. The best time of the day to see the Finland Northern Lights is between 9 p.m. and 11:30 p.m., though they are certainly not restricted to this time frame. - in: http://www.destination360.com/europe/finland/northern-lights
