We present you the February 2021 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.
Thursday, 11th February: New Moon
The New Moon occurs when the Sun and Moon are aligned, with the Sun and Earth on opposite sides of the Moon. Now, the Moon and Sun have the same ecliptic longitude, this being the first lunar phase. 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.
Saturday, 27th February: Full Moon
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.
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.
