As the third full Moon in a flavor that has four total Moons, this will be a Blue Moon past the older definition. The Moon will non really appear blue in color. The first recorded apply of the term in English language dates from 1528. Speculations on the origin of the term include an quondam English language phrase that means "betrayer Moon" or a reference to rare events, such as when grit in the atmosphere makes the Moon really appear blue. Since the 1940's the term "Blue Moon" has as well been used for the 2d full Moon in a month that has ii full Moons.
The Maine Farmer's Almanac first published "Indian" names for the full Moons in the 1930's. According to this annual, the Native American tribes of the northeastern U.s.a. called this the Flower Moon, as flowers are abundant this time of year in most of these areas. Other names include the Corn Planting Moon or the Milk Moon. Some writers necktie these Native American names to the months of our modern calendar, just I think it more likely these names were tied to the seasons. For the past year the full Moon names by flavor and by month take been out of sync, but this jump'southward "extra" Moon brings them dorsum into sync again.
As usual, the wearing of suitably celebratory celestial attire is encouraged in honor of the total Moon.
This full Moon corresponds to Vesak, likewise known every bit Buddha Purnima, a holiday (according to Wikipedia) "observed traditionally past Buddhists in Nepal, Sri Lanka, Tibet, Bangladesh, Kingdom of bhutan, Bharat and the South Eastward Asian countries of Singapore, Vietnam, Thailand, Kingdom of cambodia, Laos, Malaysia, Myanmar, the Philippines, and Indonesia. Sometimes informally chosen "Buddha'southward Altogether", it actually commemorates the birth, enlightenment (nirvāna), and death (Parinirvāna) of Gautama Buddha." The actual engagement of Vesak varies depending upon the lunar calendar in employ in the particular land or region, only this year for virtually areas information technology falls on or near the day of this total Moon. For more information see for example: https://en.wikipedia.org/wiki/Vesak
In lunisolar calendars the months change with the new Moon and full Moons autumn in the center of the lunar months. This full Moon is the centre of the 4th month of the Chinese calendar and Iyar in the Hebrew calendar. In the Islamic calendar the months starting time with the outset sighting of the waxing crescent Moon a few days after the New Moon. This full Moon is near the centre of the holy month of Ramadan, the month in which the Quran was revealed. Observing this annual month of charitable acts, prayer, and fasting from dawn to dusk is one of the Five Pillars of Islam.
Every bit usual, the wearing of suitably celebratory celestial attire is encouraged in honour of the total Moon.

Jupiter, Mercury and Mars in the Heaven
On the evening of the full Moon on May xviii, 2019, as evening twilight ends, the bright stars of the local arm of our galaxy will have already set, including all only a few stars of the constellation Orion. The planet Mars will appear in the west-northwest at nearly xvi degrees above the horizon. The Large Dipper volition appear just a little north of overhead. Towards the end of May, the planet Jupiter will begin rise in the east-southeast around the time evening twilight ends and the planet Mercury will brainstorm emerging from the glow of the setting Sun, appearing above the horizon at the time evening twilight ends on June 2, 2022 (for the Washington, DC area). Mars will continue to shift gradually towards the west-northwest, moving towards Mercury. By the night of the total Moon on June 17, 2019, every bit evening twilight ends, Mercury and Mars will announced about a degree autonomously in the w-northwest at virtually 5 degrees above the horizon. Mercury will announced brighter than Mars, with Mercury on the correct and Mars on the left. They will appear at their closest the evening later on the full Moon after side by side, on June eighteen, 2019.
On the forenoon of the total Moon on May eighteen, 2019, as morning time twilight begins, the bright planet Jupiter volition appear in the due south-southwest near 23 degrees above the horizon and the planet Saturn will appear in the south nigh 30 degrees in a higher place the horizon. The "Summer Triangle" will appear direct overhead. The "Summertime Triangle" is not a constellation, simply is made upward of Vega, the brightest star in the constellation Lyra the Harp; Deneb, the brightest star in the constellation Cygnus the Swan; and Altair, the brightest star in the constellation Aquila the Eagle. Even brighter than Jupiter, the planet Venus will be rising about 7 minutes after morn twilight begins and should be visible low in the due east-northeast until about 30 minutes earlier sunrise. By the morning of the full Moon on June 17, 2019, Jupiter will appear in the southwest about 8 degrees in a higher place the horizon and Saturn will appear in the south-southwest at well-nigh 25 degrees higher up the horizon. Venus will ascent in the east-northeast virtually 14 minutes after morning time twilight begins. The vivid star appearing well-nigh overhead will exist Deneb.
The Moons of Jupiter
We are entering a flavour that should be a good fourth dimension for using a lawn telescope to view the planet Jupiter and its four vivid Moons. Jupiter will exist at opposition, or opposite the Sun as seen from the Globe (effectively a "full Jupiter") on June 10, 2019, appearing at its closest and brightest for the yr, rising around sunset and setting around sunrise. With a small telescope you should be able to meet Jupiter's four vivid moons, Ganymede, Callisto, Europa, and Io, shifting positions noticeably in the form of an evening. Galileo was the first person known to bespeak the newly developed telescope at Jupiter, and he immediately noticed these moons that we now call the Galilean moons.
For navigation, especially at bounding main (where there are no reference points), accurate determination of longitude depends upon an accurate measurement of time. Earlier the development of accurate clocks in the late 1700's, navigators considered using the moons of Jupiter as a natural clock. It was Galileo who beginning proposed this. Meet for example: http://www.oceannavigator.com/May-June-2004/Longitude-past-Jove-navigating-with-Jupiters-moons/
At first the predictions of where the moons of Jupiter should be were off slightly, until people realized that it took fourth dimension for low-cal to go from Jupiter to Earth and that this varied as the distance from Jupiter to Earth varied. This led to one of the earliest, relatively accurate estimates of the speed of light, encounter for example: https://en.wikipedia.org/wiki/Speed_of_light
This estimate of the speed of calorie-free got meliorate after globe-wide observations of the transits of Venus in 1761 and 1769 allowed astronomers to brand the first authentic measurement of the distance from the Earth to the Sun, and from this, amend our noesis of the size of the Solar System and how the distance from Jupiter to the Earth changes over time. One of the reasons Captain Cook sailed to Tahiti was to discover the 1769 transit. The place on the north end of the island where he and Charles Dark-green observed the Transit of Venus is called Pointe Venus.
Observing the moons of Jupiter from the rocking deck of a moving ship was difficult, then using the moons of Jupiter as a time reference never really worked well for navigation at sea. Helm Cook, during one of his around-the-world voyages, observed Jupiter when on state to update his clocks and accurately locate the places he visited.
