The summer of 2014 will be bathed in moonlight as three perigee "supermoons" occur in consecutive months: July, August, September. The first supermoon is on July 12 at 08:28 UTC, the second on August 10 at 17:44 UTC and the third on September 9 at 03:30 UTC.
The scientific term for the phenomenon is perigee moon. Full moons vary in size because of the oval shape of the Moon's orbit. The Moon follows an elliptical path around Earth with one side - perigee - about 50 000 km closer than the other - apogee.
