'Supermoon' lights up sky

A "supermoon" is expected to hail the skies tonight, with the satellite expected to appear in its biggest and brightest form this year.

At this time it could appear up to 14 per cent larger and 30 per cent brighter than when it is farthest from the planet, experts said. But skywatchers will need a keen eye and clear weather to notice a significant difference - and they may have to stay up late.
