EarthSky notes that 2016 Hunter’s Moon is also a supermoon, explaining:
In some months, the full moon is closer to us in orbit than others. The 2016 Hunter’s Moon does happen to be particularly close. It’s near perigee, the moon’s closest point to Earth in its monthly orbit. Perigee comes on October 16 at 23:36 UTC (translate to your time zone), about 19 hours after the crest of the moon’s full phase at 4:23 UTC on the same date. Nowadays, people call these close full moons supermoons.
Some don’t like the word supermoon … but we like it. Full moons at their closest to Earth do look brighter. They have a larger-than-usual effect on earthly tides. Although most of us can’t detect that a supermoon appears larger to the eye, very careful and experienced observers say it’s possible.
So you won’t likely see a bigger-than-usual moon (unless you see it near the horizon, an effect known as the moon illusion). But you can notice how brightly the moon is shining, especially on the nights of October 15 and 16!
Next month – in November 2016, the full moon and perigee (closest point) come even closer together to stage the largest full moon of the year on November 14. … That November 2016 full moon will feature the closest supermoon since 1948!
