The Full Moon of June is known as the “Mead Moon,” “Strawberry Moon,”  “Rose Moon,” or “Thunder Moon.” It rises around sunset and sets around sunrise; this is 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.

Tuesday, June 9, 11:42 a.m. EDT

Last Quarter Moon

The Last Quarter Moon rises around 1:15 a.m. and sets around 1:15 p.m. It is most easily seen just after sunrise in the southern sky.

Tuesday, June 16, 10:05 a.m. EDT

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.

Observing Highlights

Double shadow transit on Jupiter

Thursday, June 4, 12:58–2:13 a.m. EDT

The shadows of Io and Ganymede will simultaneously fall on the face of of Jupiter.

Venus at greatest elongation east

Saturday, June 6, evening twilight

Venus reaches its greatest eastward distance from the sun, its orbit shown in white here. It is closing in on Jupiter.

Pallas at opposition

Thursday, June 11, 9 p.m. EDT

Pallas, the second largest asteroid, will be in opposition to the Sun. At magnitude 9.4, it will be located just south of Lambda Hercules, below the “keystone” of Hercules.

Uranus and the Moon

Thursday/Friday, June 11/12

The Moon will be close to Uranus just before sunrise. In southern Australia and the South Pacific Ocean, the Moon will actually occult Uranus, as seen here from Melbourne, Australia.

Mercury and the Moon

Monday, June 15, sunrise

As seen here from Sri Lanka, the Moon will occult the planet Mercury. Other parts of the world will see the thin crescent of Mercury very close to the thin crescent of the moon just before sunrise.


Aldebaran and the Moon

Monday, June 15, sunrise

As seen here from eastern North America, the Moon will occult the bright red giant star Aldebaran.

Solstice

Sunday, June 21, 12:38 p.m. EDT

The sun reaches its most northern point, marking the middle of the astronomical summer season in the Northern Hemisphere, and winter in the Southern Hemisphere. The actual seasons tend to lag behind the astronomical seasons by about 6 weeks.

Mercury at greatest elongation west

Wednesday, June 24, dawn

Mercury will be at its farthest from the sun, and close to the red giant star Aldebaran.

Venus and Jupiter within 0.3 degrees

Tuesday, June 30, dusk

Venus and Jupiter will pass really close to each other, appearing within the same telescope field. Both will be 32 arc seconds in diameter, but Jupiter is much further away from both the Earth and the sun, so will be much fainter than Venus.

Mercury is well placed in the eastern sky at dawn. It is better placed for observers in the Southern Hemisphere.
