The Super Moon that will shine on the night of June 23 will be the most super moon of 2013 because it will mark the time that the Earth and the Moon will be at their closest this year, and until August 2014.
The most recent occasion when the Earth and Moon were this close was on March 19 2011. The closest full moon last year was on May 6 2012.
In technical terms, the perigree – the point at which the Moon is closest to the earth within a month – and the peak of the full moon phase will be within just an hour of each other.
At the perigree, the Moon will be 357 313km from the Earth.
In the Bulgarian capital Sofia, moonrise will be about 9.02pm and moonset at 6.57am on June 24.
According to astronomers, the moon will appear just as full on June 22 as it does on June 23.
