Northern Lights - Aurora Borealis Tan Hill North Yorkshire Yorkshire Dales Kind permission granted by talented photographer Joe Burn - Freelance Photographer and Short Film Maker Tan Hill North Yorkshire - The aurora borealis (or northern lights) is a spectacular natural phenomenon which can occasionally be seen in the night sky over Britain. Once seen, it is never forgotten. AuroraWatch UK allows you to monitor geomagnetic activity in real time, and will let you know when aurora may be visible from the UK. We offer free alerts to notify you whenever aurora is likely to be seen from the UK. These alerts can be forwarded to your phone as a text message, so you will know when to look out for aurora wherever you are. From Wikipedia, the free encyclopedia See also Aurora (disambiguation), Aurora Australis (disambiguation), or Aurora Borealis (disambiguation). Pictures of the aurora australis Images of the aurora australis and aurora borealis from around the world, including those with rarer red and blue lights An aurora is a natural light display in the sky, predominantly seen in the high latitude (Arctic and Antarctic) regions.[nb 1] Auroras are produced when the magnetosphere is sufficiently disturbed by the solar wind that the trajectories of charged particles in both solar wind and magnetospheric plasma, mainly in the form of electrons and protons, precipitate them into the upper atmosphere (thermosphere/exosphere), where their energy is lost. The resulting ionization and excitation of atmospheric constituents emits light of varying colour and complexity. The form of the aurora, occurring within bands around both polar regions, is also dependent on the amount of acceleration imparted to the precipitating particles. Precipitating protons generally produce optical emissions as incident hydrogen atoms after gaining electrons from the atmosphere. Proton auroras are usually observed at lower latitudes.
