The Aurora Borealis, also known as the Northern Lights, has been visible at high latitudes over the last few nights.

This optical phenomenon results from the interaction between charged particles streaming away from the Sun upon the solar wind, and gas atoms in the upper part of the Earth’s atmosphere.

The Aurora is more likely to be visible during a period of high solar activity. 2013 sees a peak in the Sun’s  11 year solar cycle, although activity has been relatively low, so far.
