If you have an interest in Astronomy - or just enjoy seeing unusual sights in the sky - when the Moon rises tonight it will be in the Earth's shadow and appear dark red in colour. The Moon, of course, doesn't itself give off light, but 'shines' by reflecting sunlight. During a lunar eclipse the only light it receives is red, having first been scattered through the Earth's atmosphere.
Ironically, the weather forecast for Norfolk at 9.10pm tonight (when the Moon rises) is for heavy showers or thunderstorms - the first in weeks! Still: fingers crossed that the clouds stay away long enough for a glimpse of the event: if you've never seen a lunar eclipse, this will be the longest this century!
