The sun is the author!
Thanks to its charged particles if we can admire the bright dancing lights known as aurora or northern lights. These lights are seen above the magnetic poles but exactly best seen in an irregularly shaped oval centred over each magnetic pole.
Auroral displays appear in many colours, green and pink are more common. Variations are due to the type of gas particles that are colliding with atmosphere, this process occurs about 60 miles above the earth. Red auroras, that can reach lower latitudes, are reported to be located up to 200 miles from earth.
The lights appear in many forms in incredibles spectacles.
Some studies explaine a connection between the Northern Lights and sunspot activity, well known as 'solar wind'. Researchers have discovered that auroral activity is cyclic, peaking roughly every 11 years. 2013 was at the top of this cycle.
Areas that are not subject to 'light pollution' are the best places to watch for the lights. The long periods of darkness and the frequency of clear nights provide many good opportunities to watch the auroral displays, so winter of 2013 was the right year!
