Moon Phases

Mon., June 4, 7:12 a.m. EDT

Full Moon

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.

Mon., June 11, 6:41 a.m. EDT

Last Quarter Moon

The Last or Third Quarter Moon rises around 1 a.m. and sets around 1:45 p.m. It is most easily seen just after sunrise in the southern sky.

New Moon

The Moon is not visible on the date of 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. It is visible low in the west an evening or two after New Moon.

Planets

Mercury is in the evening sky but very close to the Sun all month.

Venus moves from being an evening “star” to being a morning “star” by passing in front of the Sun on June 5.

Mars is shrinking rapidly in size and brightness. On June 21 it moves from Leo into Virgo. Mars is high in the southwest at sunset and sets around 1 a.m.

Jupiter reappears in the morning sky in Taurus, approaching Venus towards the end of the month.

Saturn continues to be a  bright object in Virgo, setting around 2:30 a.m.

Uranus spends the month in the morning sky in the northwestern corner of the constellation Cetus, a rather strange place for a planet to be, since it is not one of the twelve zodiac constellations..

Neptune rises around 1 a.m. in Aquarius, and is visible the rest of the night.
