Today’s Full Moon (May 21, 2016) is the third of four full moons to occur between the March equinox and the June solstice and so it can be called a Blue Moon. To be precise, it occurs at 21:14 Universal Time, but it looked full last night and will look full to many people tomorrow night too.
No blue color to the moon, though we often see moon or night photos that have a blue cast to them because of the way cameras often interpret the color of sunlight and moonlight as respectively red/orange and blue.
Movies often use filters to change those colors. Francois Truffaut made a film I like titled Day for Night (La Nuit américaine) for the film-making process referred to in French as la nuit américaine (“American night”) of shooting outdoors in daylight with film stock balanced for tungsten (indoor) light and underexposed (or adjusted during post production) to make the final result appear as if it was filmed at night. In English the technique is called “day for night. ” As more sensitive low-light film became available and with the takeover of digital, shooting day for night is not as common. In the Truffaut film, it also implies that other things are not as they seem.
This is a Blue Full Moon by one older definition of the term as described above.A more recent definition is that a Blue Moon is a second full moon in the same month. Today’s full moon doesn’t fit that definition. That definition of the Blue Moon won’t come around until won’t happen until January 31, 2018 and will only occur 7 or 8 times in 19 calendar years.
Look up tonight and if you see the Full Moon clearly you will also see a brilliant “star” following it. That is Mars, shining much brighter than any star. Mars will also be move on May 22 into opposition and be the brightest Mars we have seen in 10 years.
This Full Moon has many names including Hare Moon, Merry or Dyad Moon, Fright Moon, Flower Moon, Frogs Return Moon, Thrimilcmonath (Thrice-Milk Month) or Milk Moon, Sproutkale, Winnemonoth (Joy Month), Planting Moon, and Moon When the Ponies Shed.
Many cultures celebrated this month. The Greek goddess Maia, the most important of the Seven Sisters (the Pleiades) and said to be the mother of Hermes, gave the name to this month. The Romans called her Maius, goddess of Summer, and honored her during Ambarvalia, a family festival for the purification and protection of farm land. In the Celtic cultures, May was called Mai or Maj, a month of sexual freedom. Green was worn during this month to honor the Earth Mother. May 1 was the Celtic festival of Beltane, a festival celebrating fertility of all things. Cattle were driven through the Beltane bonfires for purification and fertility. In Wales, Creiddylad was a character connected with this festival and often called the May Queen. The maypole and its dance is a remnant of these old festivities.
This can be the Buddha Full Moon when it occurs near the Buddha-Wesak Festival. The date of Buddha’s birthday varies but it is said that Buddha was born, died and received enlightenment on the Full Moon in Scorpio and many followers consider this the highest spiritual day of the year.
