We offer you the astronomy calendar for June 2019. 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.
Friday, June 3rd: 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.

Friday, June 10th: Jupiter at Opposition
Jupiter will be at its closest approach to Earth and its face will be fully illuminated by the Sun. It will be brighter than any other time of the year and will be visible all night long. This is the best time to view and photograph Jupiter and its moons. Jupiter comes to opposition about every 13 months. That’s how long Earth takes to travel once around the sun relative to Jupiter. As a result Jupiter’s opposition comes about a month later each year: 9th May 2019, 10th June 2019, 14th July 2020 etc.
Friday, June 17th: Full Moon
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.
This 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.
Tuesday, June 21st: 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 23rd: Mercury at Greatest Eastern Elongation
In astronomy, a planet’s elongation is the angular separation between the Sun and the planet, with Earth as the reference point. The greatest elongation of a given inferior planet (Mercury or Venus) occurs when this planet’s position, in its orbital path around the Sun, is at tangent to the observer on Earth. The planet Mercury reaches greatest eastern elongation of 25,2 degrees from the Sun. This is the best time to view Mercury since it will be at its highest point above the horizon in the evening sky.
