Astronomers are telling people to be especially watchful this evening, as a rare event could be making a very special appearance. The release of energised particles from the sun, coupled with particularly helpful overnight conditions, is predicted to make the Northern Lights (Aurora Borealis) visible much further south than normal. Interviewed earlier today by Chris Ross, Channel Sixs science correspondent, Derwent Universitys Professor Andrew Higgins told her that, 'Its a once-in-a-decade opportunity that people really shouldnt miss. Thanks to several fronts of high air pressure, the skies tonight will be particularly clear. Ill be over the moon come the dawn.'
