In Grundarfjordur, Iceland the biggest landmark is Mount Kirkjufell. Mount Kirkjufell is about 1,500 feet above sea level.Kirkjufell stands on a little peninsula of its own, a stunning backdrop for the northern lights(aurora borealis).

Aurora Borealis (Northern lights) explained- The sun acts as an enormous power plant. Energy is created deep inside the core of the sun. In the core of the sun the temperature is over an astounding 14 million degrees . The pressure is so enormous that hydrogen atoms are squeezed together into another element which is helium. This nuclear reaction releases energy and the light radiates outward from the core of the sun.The heat moves to the surface in convection cells. These electrical currents of charged gas create magnetic fields inside the sun. In some places strong magnetic fields push their way up through the surface and slow down the hot gas. The surface cools and darker sun spots appear. The electrically charged gas (plasma) drags the magnetic field further outward. The magnetic field stretches and pulls until it breaks. This results in several billions tons of plasma being hurled out from the sun (solar storm). After 18 hours the solar storm reaches earth. When the solar storm reaches our planet earths magnetic field deflects the storm. The magnetic fields couple together and create a funnel for the gas streams down on the daylight side of the pole resulting in the daylight aurora. The magnetic fields stretches further back and couples together and the magnetic rubber bands breaks and gas from the solar storm stream along the magnetic lines towards the poles on the night side  resulting in the night time aurora.
