Biggest, brightest ‘Supermoon' expected tonight



PITTSBURGH - Get your cameras ready! The year’s largest and brightest full moon will rise Sunday night.

The “Supermoon” will begin Sunday afternoon and will appear as night falls.

The phenomenon happens when the full moon coincides with the moon’s closest approach to the Earth during its elliptical orbit around us.

The last “Supermoon” happened in July, but this one will mark the moon’s closest encounter with Earth for all of 2014.
