Impressive 'supermoon' to shine Saturday

A bigger and brighter ''supermoon'' will appear Saturday as the moon makes its closest approach to Earth in nearly 20 years.

The full moon, or supermoon, rising in the east at sunset on March 19 will appear 14 percent bigger and 30 percent brighter at its peak. The moon will be more than 221,960 miles away- the closest it has been to earth since March 1993.

"No correlation at all between the proximity of a full moon to the earth other than a slight rise and decrease in high and low tide. That is it. The best time will be after the moon rises," ABC7 Meteorologist Mike Caplan said Friday.
