Supermoon?

"Supermoon".  OK, so it's not a scientific term coined by astronomers but more of a descriptive term used by observers.  This phenomenon is the coincidental occurrence of a full moon and perigee, the point at which the moon  is at 90% or greater of its mean closest approach to earth.  It is at the perigee that the moon appears largest.   By the way, apogee is the furthest earth to moon distance.  From what I understand the supermoon may appear 14% larger and 30% brighter than lesser full moons but to the casual observer it may be hard to tell any difference.  When the moon is at perigee, the closest distance from earth, there is much more gravitational pull which contributes to higher tides or greater variation in the high and low tide.  All very interesting but not exactly "earth shaking".
