A Beginners Guide to the Northern Lights – What are the Northern Lights?
The Northern Lights, or Aurora Borealis, are a stunning natural phenomenon that occurs in the Earth’s polar regions. They are caused by collisions between charged particles from the sun and the Earth’s atmosphere. The resulting display of light can be seen in various colours, including green, purple, pink, and blue.
The KP Index
The KP Index is a measure of geomagnetic activity, which is influenced by solar flares. A higher KP index indicates a greater chance of seeing the Northern Lights. The scale ranges from 0 to 9, with 0 being the least active and 9 being the most active.
Solar Flares and the Northern Lights
Solar flares are powerful bursts of energy that occur on the sun’s surface. These flares release charged particles, known as solar wind, into space. When the solar wind reaches Earth, it interacts with the planet’s magnetic field. This interaction causes the charged particles to be diverted towards the poles, where they collide with the Earth’s atmosphere. The collisions create the dazzling display of light that we know as the Northern Lights.
Why Do the Colors Change?
The colours of the Northern Lights vary depending on the type of gas that the charged particles collide with. Oxygen atoms produce green and red hues, while nitrogen atoms create blue and purple colours. The altitude of the collisions also plays a role in determining the colour.
Where Can You See the Northern Lights?
The Northern Lights are most commonly seen in high-latitude regions, such as Alaska, Canada, Iceland, Norway, Sweden, and Finland. These areas are known as the “Aurora Zones.” However, it’s possible to see the Northern Lights from lower latitudes during periods of intense solar activity.
When Can You See the Northern Lights?
The best time to see the Northern Lights is during the dark winter months. The lack of daylight provides ideal conditions for viewing the aurora. However, it’s important to note that the Northern Lights can be seen at any time of year, provided there is enough solar activity and the sky is clear.
