The next Supermoon is on 2 January 2018
The full Moon is at 02:24 at 11˚ 37" Cancer. She will rise at 16:54 and set at 08:05 (London times).
The Moon will look really big and bright on both nights of the 1/2 January. Even though she is about 7% bigger than a usual full Moon this won’t be very noticeable - however the brightness will be!
So wrap up warm and get out and bathe in the Super Moonlight! Look out at sunset when the full Moon rises as she looks even bigger and more magnificent when she's on the horizon. Enjoy!
This is the first and closest Supermoon of 2018.
What happens on a Supermoon?
The Supermoon occurs when the Moon is full at the same time as her orbit is closest to the Earth.
The combination of a full Moon and the close approach will mean that the Moon will appear bigger and brighter than usual. Supermoons occur roughly every 13 months.
The Supermoon may look 7% larger than our usual full Moon and can be about 16% brighter. The Supermoon is especially bigger and brighter in the winter* when the Earth is closer to the Sun and the gravitational pull of the Sun pulls the Moon closer to Earth. Thus, the winter Supermoons look bigger and brighter than the summer ones*.
The opposite of the Supermoon is the Micromoon or Minimoon - when the Moon is at her furthest point from the Earth - she may look 7% smaller than the usual full Moon.
Supermoon's also bring high tides over the few days arround the Full Moon.
