The first super moon of the year is almost here, and this year it will coincide with the last full moon of the winter. This is expected to be the biggest and brightest moon all year, and will reach its peak around 1:48 pm EDT on Monday, March 9.
A supermoon occurs when the full moon is closest to Earth in its elliptical orbit which ends up making the moon appear larger and brighter than it usually does.
Something called a "Worm Moon" will appear the day before and after the super moon as well.
According to NASA, the full moon in March was named the Worm Moon by the indigenous tribes of the northern and eastern US after the earthworm casts, which is fertilizer produced by worms. Worm Moon is the most commonly used name for the March moon, but it also goes by Sap Moon, Crow Moon, Crust Moon, Sugar Moon, and Lenten Moon.
The Old Farmer’s Almanac says that, “At this time of the year, the ground begins to soften enough for earthworm casts to reappear, inviting robins and other birds to feed — a true sign of spring.”
The name supermoon was coined by astrologer Richard Nolle in 1979, in Dell Horoscope magazine. He came up with the name while reading “Strategic Role Of Perigean Spring Tides in Nautical History and Coastal Flooding” published in 1976 by NOAA Hydrologist Fergus Wood.
The real association of the Moon with both oceanic and crustal tides has led to claims that the supermoon phenomenon may be associated with increased risk of events like earthquakes and volcanic eruptions, but no scientifically proven link has been found.
Out of the possible 12 or 13 full moons each year, usually only about three or four fit the classifications of a supermoon. This year, supermoons will come again in both April and May.
