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. Here you can find the astronomy calendar for October 2018.

Monday, November 5th, Tuesday, November 6th: Taurids Meteor Shower – the Taurids are an annual meteor shower, producing only about 5-10 meteors per hour. The Taurids are actually two separate streams, with a Southern and a Northern component. The Southern Taurids are produced by debris left behind by Comet 2P Encke, while the Northern Taurids produced by dust grains left behind by Asteroid 2004 TG10. They are named after their radiant point in the constellation Taurus, where they are seen to come from in the sky. Because of their occurrence in late October and early November, they are also called Halloween fireballs. It peaks this year on the the night of November 5.

November 2018 Astronomy Calendar

Tuesday, November 6th: 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 23.3 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.

Wednesday, November 7th: 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.

Saturday, November 17th, Sunday, November 18th: Leonids Meteor Shower – the Leonids are a prolific meteor shower associated with the comet Tempel-Tuttle. The Leonids get their name from the location of their radiant in the constellation Leo: the meteors appear to radiate from that point in the sky. The Leonids is an average shower, producing up to 15 meteors per hour at its peak. This shower is unique in that it has a cyclonic peak about every 33 years where hundreds of meteors per hour can be seen. That last of these occurred in 2001. The Leonids is produced by dust grains left behind by comet Tempel-Tuttle, which was discovered in 1865.

Friday, November 23rd: 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. November’s full Moon was called the Beaver Moon by both the Algonquin tribes and colonial Americans, because this was the month to set beaver traps before the swamps froze, to ensure a supply of warm winter furs. The November full Moon was also called the Full Frost Moon by other Native American tribes.
