We offer you the astronomy calendar for July 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.

Tuesday, 2nd July: 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.

Tuesday, 2nd July: Total Solar Eclipse

A total solar eclipse occurs when an observer on Earth passes through the shadow cast by the Moon which fully blocks the Sun. This can only happen when the Sun, Moon and Earth are nearly aligned on a straight line in three dimensions (called syzygy) during a new moon when the Moon is close to the ecliptic plane.

The path of totality will only be visible in parts of the southern Pacific Ocean, central Chile, and central Argentina. A partial eclipse will be visible in most parts of the southern Pacific Ocean and western South America.

This is the only solar eclipse in 2019. On January 6th, there was a partial solar eclipse, while on December 26th there is an annular solar eclipse.

Tuesday, 9th July: Saturn at Opposition

Saturn 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 Saturn and its moons.


Tuesday, 16th July: 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.

July full moon was known by early Native American tribes as the Full Buck Moon, because this month is when the new antlers of buck deer push out from their foreheads in coatings of velvety fur. This moon has also been known as the Buffalo Moon, the Bull Moon, the Hot Sun Moon, the Hay Moon, the Elk Moon and the Thunder Moon.


Tuesday, 16th July: Partial Lunar Eclipse

A partial lunar eclipse occurs when the Moon passes through the Earth’s partial shadow, or penumbra, and only a portion of it passes through the darkest shadow, or umbra. During this type of eclipse a part of the Moon will darken as it moves through the Earth’s shadow.

This eclipse is visible in much of Europe and Asia, Australia, Africa, South-East of North America, South America, Antarctica, Pacific and Indian Ocean.

The first lunar eclipse of the year – a total lunar eclipse – took place on January 21st.


Sunday, 28th, Monday, 29th July: Delta Aquarids Meteor Shower

The Southern Delta Aquarids are a meteor shower visible from mid-July to mid-August each year. It peaks this year on the night of July 28 and morning of July 29. The Delta Aquarids is an average shower that can produce up to 20 meteors per hour at its peak. It is produced by debris left behind by comets Marsden and Kracht. Best viewing will be from a dark location after midnight. Meteors will radiate from the constellation Aquarius, but can appear anywhere in the sky.
