For Philippine observers, the biggest full moon will exactly occur on March 20, 2011 at 2:10am PST (5:00am Manila, Philippines time).
“The ‘supermoon’ will be closest to the Earth in 18 years today and will appear to be the biggest and brightest of 2011, Director of Science Popularisation Association of Communicators and Educators (SPACE) C B Devgun told PTI.
Saturday’s full moon will be around 10 per cent bigger and 30 per cent brighter as compared to other full moons during the year, he said.
The term ‘Supermoon’ was first coined by Astrologer Richard Nolle in 1979. According to him, it is a situation when the moon is slightly closer to the Earth in its orbit than average, which is 90 per cent or more of its closest orbit, and the moon is a full or new moon.
Today, the moon will be only 3,56,577 kms away from the Earth, the closest while at the full moon phase in 18 years.
Earlier, there were supermoons in 1955, 1974, 1992 and 2005.
