The National Astronomical Research Institute of Thailand (NARIT) is recommending that people take the opportunity to view the first of only two super full moons of this year, visible from 7pm tonight.

The moon can appear up to 14% larger and 30% brighter than when it is at its farthest point from Earth, because it is the moon’s arrival at its perigee, its closest orbital point to Earth.

The moon will be about 384,400 km from Earth, which is about 8% closer than average distance for a full moon. This fluctuation in the moon’s distance is caused by its orbit around the Earth not being perfectly circular, but very slightly elliptical.

More information about this celestial phenomenon and about techniques for of taking pictures of the event can be found at NARIT’s website.
