We present you the astronomy calendar for June 2021. Astronomy is the foundation upon which astrology can operate. Actually, astrology and astronomy were treated together, under the Latin name of astrologia, being separated only by the Western 17th century philosophy. One thing is sure: a good astrologer needs to study astronomy.
Thursday, 10th June: New Moon
The New Moon is when the Sun and Moon are aligned, with the Sun and Earth on opposite sides of the Moon. The new moon is the first lunar phase, when the Moon and Sun have the same ecliptic longitude. At this phase, the lunar disk is not visible to the unaided eye, except when silhouetted during a solar eclipse. This is the best time of the month to observe faint objects such as galaxies and star clusters because there is no moonlight to interfere.
Thursday, 10th June: Annular Solar Eclipse
An annular solar eclipse occurs when the Moon is too far away from the Earth to completely cover the Sun. This results in a ring of light around the darkened Moon. The Sun’s corona is not visible during an annular eclipse.
The path of this eclipse will be confined to extreme eastern Russia, the Arctic Ocean, western Greenland, and Canada. A partial eclipse will be visible in the north-eastern United States, Europe, and most of Russia.
Monday, 21st June: June Solstice
This is the first day of summer (summer solstice) in the Northern Hemisphere and the first day of winter (winter solstice) in the Southern Hemisphere. The June solstice marks the first day of astronomical summer in the Northern Hemisphere and the first day of astronomical winter in Southern Hemisphere. The North Pole of the Earth will be tilted toward the Sun, which will have reached its northernmost position in the sky and will be directly over the Tropic of Cancer at 23.44 degrees north latitude. This is also known as the northern solstice.
Thursday, June 24th: Full Moon and Supermoon
The full moon is the lunar phase when the Moon appears fully illuminated from Earth’s perspective. This occurs when Earth is located directly between the Sun and the Moon (more exactly, when the ecliptic longitudes of the Sun and Moon differ by 180°). This means that the lunar hemisphere facing Earth – the near side – is completely sunlit and appears as a circular disk, while the far side is dark.
June full moon was known by early Native American tribes as the Full Strawberry Moon, because it signalled the time of year to gather ripening fruit. It also coincides with the peak of the strawberry harvesting season. This moon has also been known as the Full Rose Moon, the Full Honey Moon, the Corn-Planting Moon, the Mead Moon and the Thunder Moon.
