Scientists estimate the "supermoon" rose in the east at sunset appeared 14 percent bigger and 30 percent brighter at its peak.
Full moons vary in size because of the oval shape of its orbit, with one end closer to Earth. On Saturday, the moon will be 221,565 miles away — the closest to Earth since March 1993.
While Saturday's full moon was brighter than normal, it won't be as luminous as the near-supermoon of 2008 when it was higher in the sky.
This type of full moon tends to bring a range of high and low tides, but experts say that's nothing to worry about. Nor is there any truth to the superstition that supermoons cause natural disasters.
