Add Missing apostrophes- Astronomers are telling people to be especially watchful this evening, as a rare event could be making a very special appearance. The release of particles from the sun, coupled with particularly helpful overnight conditions, is predicted to make the Northern Lights visible much further south than normal. Interviewed earlier today by Chris Ross, Channel Sixs science correspondent, Derwent Professor Andrew Higgins told her that, " a once in a decade opportunity that people really shouldn't miss. Thanks to several fronts of air pressure, the skies tonight will be particularly clear. The moon come the dawn."
