Star gazers across the world, recently witnessed a rare supermoon eclipse and a spring equinox (time of the year when day and night are of equal duration).
Supermoon is an astrolonomical alignment which occurs when the full or new moon is close to the horizon, causing it to appear bigger and brighter. During this time, the moon can appear up to 30 percent brighter and 14 percent bigger to skywatchers on Earth. In other words when the moon closely coincides with perigree – the closest point to Earth in its orbit, the Supermoon phenomenon occurs. The name Supermoon was coined by Richard Nolle, an astrologer, some 30 years ago.
While orbiting around Earth the full moon or new moon gradually comes nearer, until it reaches its closes point, making it a Supermoon.
Although the alignment causes a small increase in tectonic activity, the effects of Supermoon on Earth are minimal. Scientists claim they haven’t found anything significant that can link the supermoon to anything unusual like natural disasters.
Most of the time, there are between three to six supermoons a year. However, 2015 will have six Supermoons – three of them already occurred. Next ones would be in Aug, Sep and Oct. The full moon on Sep 28 would be the closest supermoon of the year (356,896 km).
