An event not to be missed this Monday November 14. The “super extra” moonlight will be visible today, if the weather is mild. The very rare event occurs during a quite close perigee. This will result in the largest super-moon since 1948. The next is scheduled for November 2034, according to the Mauritius Astronomical Society.
Full moons occur when the moon is on the side of the earth in front of the sun, and the three celestial bodies are aligned. Sometimes they do it very well, so we have a lunar eclipse. But today, it will not be the case. Result: a super-moon.
Nevertheless, it is interesting to note that the circular path of the moon around the earth, called its orbit, is not a perfect but slightly elongated circle. This means that sometimes the full moon in its orbit reaches a minimum distance. When it reaches a maximum distance from the earth, it is called apogee. In most cases, full moons occur when the position of the moon is somewhere between these apogees and perigee.
The full moons at the perigee are called super-moons – super moons or super extra – by amateur astronomers (and sometimes by astrologers). Super moons are slightly larger and brighter than the full moons that occur at the peak.
