Here, you can find March 2020 astronomy calendar. 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. For sure: a good astrologer needs to study astronomy.
9th March: Full Moon and Supermoon
The full moon is the lunar phase when the Moon appears fully illuminated from Earth’s perspective. This takes place when Earth is located directly between the Sun and the Moon. More exactly, the ecliptic longitudes of the Sun and Moon differ by 180°). This means that the lunar hemisphere facing Earth – the near side –appears as a circular disk (being completely sunlit), while the far side is dark.
This full moon is also the second supermoon of 2020 (the first was on 9th February, the third on 8th April and the fourth and the last on 7th May). The Moon will be at its closest approach to the Earth and may look slightly larger and brighter than usual.
March full moon was known by early Native American tribes as the Full Worm Moon because this was the time of year when the ground would begin to soften and the earthworms would reappear. Other names for this full moon were Wind Moon, Little Grass moon, Sore-Eye Moon, Crow Moon, Sap Moon, Lenten Moon, Chaste Moon, Death Moon and Crust Moon.
20th March: March Equinox
The March equinox or Northward equinox is the equinox on the Earth when the subsolar point (the point at which the sun is perceived to be directly overhead that is, where the sun’s rays strike the planet exactly perpendicular to its surface) appears to leave the Southern Hemisphere and cross the celestial equator, heading northward as seen from Earth.
The March equinox is known as the vernal equinox in the Northern Hemisphere and as the autumnal equinox in the Southern. So, this is the first day of spring (vernal equinox) in the Northern Hemisphere and the first day of fall (autumnal equinox) in the Southern Hemisphere.
The Sun will shine directly on the equator and there will be nearly equal amounts of day and night throughout the world.
24th March: 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.
24th March: 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 27.8 degrees from the Sun. March 24th 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.
24th March: Venus 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 planet Venus reaches greatest eastern elongation of 46.1 degrees from the Sun. March 24th is the best time to view Venus since it will be at its highest point above the horizon in the evening sky.
