We present you the February 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 February: 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 first supermoon of 2020 (the second is on 9th March, 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.
The February Full Moon was known by early Native American tribes as the Full Snow Moon, because, usually, the heaviest snows fall in this month. Hunting becomes very difficult, and hence to some tribes this was known as the Full Hunger Moon. Other names for this full moon were Raccoon Moon, Bare Spots on the Ground Moon, Storm Moon.
10th February: 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 18,2 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.
23rd February: 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.
