The great borealis Hunt

There are strong predictions that the Northern Lights might be visible over large parts of Britain tonight. So good luck to all Cranfieldians in the great  Borealis Hunt. Check it out in the 

Daily Telegraph







The scientific name for the Northern Lights is aurora borealis, named after the Roman goddess of the dawn. Northern Lights are essentially created by the interaction of the Earth’s magnetism and solar wind.
The light displays occur when solar particles enter the Earth’s atmosphere in an oval area above the magnetic pole – the aurora belt. These particles emit burning gases upon impact, which produce different coloured lights: oxygen produces green and yellow; nitrogen produces blue…
The best displays occur in the northern parts of Sweden, Norway and Finland, Greenland and Svalbard, Alaska, Canada and Russia. The best months to see them are in February and March and then in late October and November.
