Spring buds are silhouetted against the rising full moon in Washington, March 19, 2011. Saturday saw the rise of a full moon called a "Super Moon" when it arrived at its closest point to the Earth in 2011, a distance of 221,565 miles or 356,575 km away Reuters

Skygazers across South America, Europe, Africa, Asia and Australia will get witness the lunar phenomenon called "Pink Moon" on Friday, April 19 at 7:12 a.m. EDT.

According to Space.com, for observers in the U.S. east coast, the Pink Moon will rise at around 8 p.m. on April 19 and set at around 7 a.m. the next morning. The moon will be in the constellation Virgo. The sun will rise about an hour before moonset on April 20, so for about an hour, the nearly full moon and the sun will both appear in the sky.

The Pink Moon will look slightly bigger than normal because the moon will be three days’ pass perigee – the nearest location of natural satellite such as moon to Earth – so it will be almost like a “supermoon.” Supermoons happen when the full moon coincides with perigee, but the difference in size even for these "super" natural satellites is usually too small to notice for unaided eye.

As for how it got its name, April’s full moon is known as the Full Pink Moon by the Native American tribes, even though it does not actually turn pastel pink as the name suggests. It is based on the aboriginal calendar which is different from the western calendar. It is a lunar calendar that is based on the observation of people that are closely linked to nature.

During ancient times, Native Americans did not have means to accurately track time. They used the different full moons to determine the coming season. Interestingly, Colonial Americans adopted the system through their Farmer’s Almanac.

The name of the Pink Moon comes from pink flowers that bloom in the early spring, known as “moss pink” or ground phlox. Ground Phlox is a flowering plant that creeps on the ground and covers the rocky soil.

Other native and indigenous people have different views about the Pink Moon. The Ojibwe people indigenous to North America called it the Sucker Moon after the common fish species known as suckerfish.

The Tlingit of the Pacific Northwest call the April full moon "X'eigaa Kayaaní Dís," meaning "Budding moon of plants and shrubs," according to the Tlingit Moon and Tide Teaching Resource published by the University of Alaska at Fairbanks.

In New Zealand, the Māori people called the April moon "Paenga-whāwhā," describing the month as a time when "all straw is now stacked at the borders of the plantations." For the Jewish people, it celebrates the escape from Egypt.

The April full moon has also been called the Egg Moon because it is the egg-laying season among animals and coincides with Easter season, along with other names such as Fish Moon.
