Lunar Perigee & Apogee

Nick Anthony Fiorenza

The Lunar Perigee is when the Moon is closest to the Earth during its monthly orbit. The Lunar Apogee is when the Moon is furthest from Earth. Generally, the Moon looks about 14% larger and 30% brighter at its perigee compared to its apogee. The Moon looks additionally larger when it is on the horizon due to atmospheric distortion. Thus when a Full Moon occurs during a Lunar Perigee, the Full Moon will look spectacular when it rises on the eastern horizon at sunset, especially with the right atmospheric conditions.

The New Moons occurring in February and March 2015 synchronize with the Lunar Perigees. The Full Moons in August, September and October 2015 synchronize with the Lunar Perigees. Thus they will look extra large and will produce an increase in gravitational and tidal forces.

Both New Moons and Full Moons that occur near Lunar Perigees can produce an increase in the potential for seismic activity, and even more so when there is an eclipse, due to the direct alignment of the Sun, Earth and Moon.
