The Super Moon phenomenon already registered this year to July 12 and will return to repitir to September 9, but Lisbon Astronomical Observatory said that the Super Moon of tomorrow will be the most significant of all.
On Sunday, the Moon will be closer to the earth at 18h43 from mainland Portugal and reaches the stage of Full Moon at 19h09. The Super Moon can be observed between 20h16 August 10 and 6:22 a.m. to August 11.
There are several initiatives marked to indicate the phenomenon, including a 30-minute session in the Planetarium Calouste Gulbenkian in Lisbon, which will be followed by external observation.
A Super Moon occurs every year, always during the full moon, and is marked by the instant of Full Moon when the Moon is at a distance from Earth of less than 110% of the perigee (point of orbit closest to the Earth) of its orbit.

According to the Astronomical Observatory of Lisbon, with the Moon near the horizon, an extra magnification effect occurs, but that is only an illusion produced for reasons not fully understood by astronomers and psychologists.
The average distance between Earth and the Moon is 384,400 kilometers but during the perigee is reduced to 363 100 kilometers on average. During the Super Moon natural satellite will be 356,895 miles from Earth.
The Super Moon combines up this year with the most famous meteor shower, the Perseids, which will take place between 11 and 13 August, helping to illuminate the sky while this is bad news for who enjoy watching shooting stars, since the brightness of the Super Moon will help overshadow Perseides.
The phenomenon can be seen worldwide, since Heaven remains free of clouds.
NASA prepared a video, which we reproduce here, which explains the Perseides and also their combination with the Super Moon.
