A Supermoon is an astrological term for what astronomers call perigee-syzygy or perigee New/Full Moon; aka when the New or Full Moon is at its closest to Earth on its orbit. This makes the Moon look heap big and bright, supremely photogenic. Supermoons have a noticeable effect on the tides above and beyond regular New/Full Moons, at an increase of around 19% (which is either significant or insignificant, depending on who you ask, but is still tangible either way).
Astrologically, one could look at Supermoons as reduced eclipses in intensity and duration. The effects last as long as any typical New/Full Moon but man, what a punch they can pack while in effect!
Sometimes Supermoons coincide with actual eclipses, such as we’ll see in 2018. Not too soon to mark your calendar, both for dramatic sky watching and photography opportunities and for unfolding of events.
