Although the term is anything but scientific, with the super Luna expression means the coincidence of the full moon with the moment of closest approach to Earth (perigee).
It is not a rare event (happens about once a year) and even nefarious (as many conspiracy theorists tend to believe). But November 14, 2016, when the Moon will enter the phase of the full moon
around a couple of hours after perigee, lovers of night sky will witness a super moon more "super".
WHEN. At 12:24 Italian time, in fact, the Moon will be located at the minimum distance from Earth 356,511 km. Just under two and a half hours later, at 14:52 Italian time, our satellite will reach the peak of the full moon phase.
Not only it will be the closest full moon to the Earth in 2016, but will also be the largest full moon visible from 70 years: so the last occurred in 1948, and the next will come Nov. 25, 2034.
WHAT WE WILL SEE? A full moon at perigee can be 14% bigger and 30% brighter than a full Moon in apogee, but it is not always easy to tell the difference. The brightness can be shielded by clouds or canceled by the city lights; and no real references to heaven to "take steps", the advantage in terms of angular diameter (that is, the measure of its diameter than the distance from the observer) is likely to get lost. A Moon very near the horizon and ground reference points (such as trees or houses), for example, is apparently very large although in apogee, as you can see in these photos of Super Moons some time ago.
