Basically the most restless the sun, the more chances to see the aurora.
We know there is a so-called 11-year cycle for auroral displays. Chances peak around 10 pm, which is why most tour operators start their hunt at around 6 - 6:30 pm. The best time to see the northern lights is from 6 pm to 4 am. We saw the northern lights in Norway on the 1st of October. The northern lights can be observed from late August until mid-April, although for maximum chances you should probably expect to see them from late September until late March. When is the best time to see the Northern Lights Once you see the northern lights once, you become addicted to this incredible natural phenomena and you'll want to hunt them all across the globe. So you see, every aurora dance is unique and special in its own way. The blue or purple aurora is produced by nitrogen molecules.
The very rare all-red aurora is produced by high altitude oxygen molecules located at 300 km above Earth. For example, the common greenish aurora is produced by oxygen molecules located at around 100 km above the Earth. Here's a really interesting fact: the colour of the aurora is determined by the type of gaseous particles which collide between our planet's atmosphere and the charged particles from the sun. Those eerie glows can also take many forms like small patches, clouds of colour, rippling curtains and dynamic rays. The aurora display can appear like a celestial dancing spectacle in shades of red, yellow, green, blue and violet. In the southern hemisphere, they are called the southern lights or Aurora australis. In the northern hemisphere, they are called the northern lights or Aurora borealis. These lights can be seen above the magnetic poles in the northern or southern hemisphere.
The northern lights are created from a collision between electrically charged particles from the sun that enter the atmosphere of the earth.
