We offer you the astronomy calendar for August 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.




Thursday, August 1st: 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, August 9th: Mercury at Greatest Western Elongation

In astronomy, a planet’s elongation is the angular separation between the Sun and the planet, with Earth as the reference point. The planet Mercury reaches greatest western elongation of 19.0 degrees from the Sun. August 9th is the best time to view Mercury since it will be at its highest point above the horizon in the morning sky. Look for the planet low in the eastern sky just before sunrise.




Monday, August 12th, Tuesday, August 13th: Perseids Meteor Shower

The Perseids are prolific meteor showers associated with the comet Swift–Tuttle. The Perseids are so called because the point from which they appear to hail (called the radiant) lies in the constellation Perseus. This year, the meteor shower’s peak will be on the night of August 12th and the morning of August 13th. The nearly full moon will block out most of the fainter meteors this year, but the Perseids are so bright and numerous that it could still be a good show. Best viewing will be from a dark location after midnight

 

Thursday, August 15th: 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.

August full moon was known by early Native American tribes as the Full Sturgeon Moon, since sturgeon, a large fish of the Great Lakes and other major bodies of water were most readily caught during this month.

This moon has also been known as Harvest Moon, Cow Buffalo Moon, Red Moon, Corn Moon or Green Corn Moon and Grain Moon.

 

Friday, August 30th: New Moon and Black Moon

As we said above, 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.

This is also a black moon, because is the second new moon in the same calendar month, after August 1st new moon. The precedent black moon was on 30th October 2016. According to another use of the term (the third new moon in a season that has four new moons, instead of three), the next new moon will be on 22nd May 2020.
