Get ready to witness a supermoon eclipse on September 27. Skywatchers from South America, eastern Pacific Ocean region, North America, Europe and western Asia will be among those lucky people who will be able to see the rare event.

According to experts, the rare event is taking place due to oval orbit of the earth’s natural satellite. When a partial eclipse occurs, only an expert can observe it. During that event, the moon’s brightness gets reduced. When the moon is closer to earth, it is called ‘perigee’, while the opposite of it is ‘apogee’.

This month’s total lunar eclipse is very special as it is occurring with a supermoon. According to experts on the matter, the supermoon eclipse of this month is the first since 1982. There will be no such event until 2033, they said. A supermoon is a phenomenon when a full moon is at the perigee. On September 27, people from South America, eastern Pacific Ocean region, North America, Europe and western Asia will be able to get a glimpse of a total eclipse.

Noah Petro, deputy project scientist for the Lunar Reconnaissance Orbiter at NASA's Goddard Space Flight Center in Greenbelt, said, “When the moon is farthest away, it's known as apogee, and when it’s closest, it's known as perigee. On September 27, we're going to have a perigee full moon — the closest full moon of the year”.
