At perigee, the Moon approaches the Earth from a distance as close as 225,623 miles (363,104km).
At its farthest point, at apogee, the Moon sits roughly 252,088 miles (405,696km) from Earth.
Supermoons, like the one next week, are best seen around the time of moonrise or moonset.
Mr Masi said observing the Full Moon around the time of twilight is a particularly splendid opportunity to see the Moon in action.
