The full moon will dip through Earth’s shadow in a June 2012 partial lunar eclipse, before Venus crosses the face of the Sun in a rare transition. This type of full moon last occurred more than 100 years ago.
A partial eclipse of the Moon will be visible over western North America just before sunrise on June 4.
The Full Moon of June is usually called the Flower Moon. In Algonquian it is called Strawberry Moon. Other names are Honey Moon, Rose Moon, Hot Moon, and Planting Moon.
In Hindi it is known as Wat Poornima. Its Sinhala (Buddhist) name is Poson. The Full Moon rises around sunset and sets around sunrise, the only night in the month when the Moon is in the sky all night long.
The rest of the month, the Moon spends at least some time in the daytime sky.
It is not visible on June 19th, the date of the New Moon, because it is too close to the Sun, but can be seen low in the east as a narrow crescent a morning or two before, just before sunrise.
The event will also mark the last chance to see Venus pass between Earth and the Sun in the 21st century. The 2012 transit of Venus is the last one visible from Earth until 2117.
Triple conjunction: Moon, Venus, Jupiter
The Moon, Venus, and Jupiter will be the three brightest objects in the night and will be gathered together in a triple conjunction at dawn in the constellation Taurus.
Just after sunset on June 21, a slender crescent Moon points the way to the planet Mercury and the twin stars Castor and Pollux in the constellation Gemini.
