COLUMBUS (WCMH) — Late tonight (Feb. 18-19), the full moon will be our second and brightest supermoon of the year — the one time you should really take in a view of the moon, if feasible. The moon will be at its closest point to Earth during 2019 and receive maximum illumination (from the sun).
Peak brightness should be in the hours before dawn, illuminating the Full Snow Moon.
A supermoon, which usually occurs several times in a year, is a full or new moon that coincides with the point when the moon is closest to Earth in its orbit (perigee).
Because the moon will be fully illuminated by reflected sunlight and unusually close to Earth at a distance of 221,681 miles, the moon will appear 7 percent larger and 15 percent brighter than normal.
The modern definition of a supermoon is a full or new moon coming within 90 percent of its closest position relative to Earth during the year.
At perigee, the moon is about 30,000 miles closer compared to the farthest point in the year, or apogee.
