11-8 watch the nearest "super moon"

The night of August 10-11 (Vietnam time), the closest and brightest full moon of 2014, also known as the closest "supermoon".

According to Mr. Dang Tuan Duy - Chairman of the Ho Chi Minh City Amateur Astronomy Club (HAAC), the remarkable thing about the event on August 10 and 11 is the time when the full moon and the moon reach the most extreme position (perigee), almost at the same time (only 20 minutes apart). This extreme position is also the time when the moon reaches the closest position to the Earth in 2014, at a distance of 356,896km (according to fourmilab). Scientists say the moon will not approach the Earth at a similar distance until September 28, 2015.

This is an interesting astronomical phenomenon because according to some scientists, during a "supermoon" the Moon can appear 12-14% larger and 30% brighter than usual. However, it is difficult for us to detect this difference with the naked eye without measuring tools (the best way to distinguish is to take a photo of the normal Moon and the Moon during a "supermoon" with the same focal length of the camera and then compare).

In 2014, the Moon also had several full moons (June 13 and September 9) and were also called "supermoons", but the distance between the Moon and Earth was greater and the time between the perigee and the full moon was also quite far apart, not at the same time compared to August 10 and 11.
