Another year is coming to an end, the new year is approaching. Let’s find out what exciting astronomical events await us in November 2021.
This astronomical calendar document is mainly translated from the Seasky website, in addition to many reputable scientific websites such as Earthsky, NASA, Time & Date, etc. converted to Vietnamese time.
November 5 – New Moon
The Moon and Sun will be on the same side of Earth, making it impossible to see it in the night sky. This phenomenon occurred at 04:15 (Vietnam time). This is the best time of the month to observe low-light objects such as galaxies and star clusters as they will not be affected by moonlight.
November 4-5 – Taurids Meteor shower
This is a small and prolonged meteor shower, with a frequency of 5-10 meteors per hour at its peak. Taurids are unusual in that there are two distinct streams of matter within them. One is a stream of material from dust particles from asteroid 2004 TG10. The second is a stream of matter formed from the debris of comet 2P Encke. The Taurids meteor shower occurs every year from September 7 to December 10. This year, it peaked on the night of November 4. At this time, the New Moon phase darkens the sky, creating excellent conditions for viewing meteor showers. The ideal viewing time is just after midnight, in a sufficiently dark place, away from city lights. The Taurids meteor shower originates from the constellation of Taurus, but it can appear anywhere in the sky.

November 5 – Uranus is in opposition
This blue planet will be closest to Earth, with the Earth-facing hemisphere fully illuminated by the Sun. This is the best time to observe Uranus when it shines the brightest of the year and can be observed all night. Due to its distance from Earth, Uranus can only be seen as a small blue and green dot, even with the most modern telescopes.

November 17-18 – Leonid meteor shower
The Leonids are medium-sized meteor showers, with a rate of 15 meteors per hour at its peak. The Leonid meteor shower is unique because the meteor vortex occurs every 33 years. It is then possible to observe the production of hundreds of shooting stars every hour. The most recent meteor vortex occurred in 2001. The Leonid meteor shower is formed from dust particles from comet Tempel-Tuttle, discovered in 1865. The Leonids appear each year from November 6 to 30. This year, it peaked on the night of November. November 17 and the morning of November 18. Unfortunately, at this time, the bright light of the quasi-full moon in the sky will eclipse the shooting stars, only the brightest can be observed. If you’re patient enough, you can still see a few bright shooting stars in the sky. A dark enough place after midnight will give you the best view. The meteor shower originates from the constellation Leo (Leo) but it can appear anywhere in the sky.

11/20 – Full Moon
The Moon and the Sun are on opposite sides of the Earth, so the Earth-facing hemisphere of the Moon is entirely illuminated by the Sun. This phenomenon occurred at 03:59 (Vietnam time). This full moon was called the beaver moon by ancient Native American tribes because it was the time when beaver traps were set in swamps and glaciers. This Full Moon is also known as Frost or Dark Moon.
19/11 – Partial lunar eclipse
A partial lunar eclipse occurs when the moon passes through Earth’s penumbra (penumbra) and only part of it enters Earth’s shadow (umbra). When this happens, part of the moon will be evacuated as it passes through Earth’s shadow. A partial lunar eclipse can be seen from most of eastern Russia, Japan, the Pacific Ocean, North America, Mexico, Central America, and parts of southwestern Russia. ‘America.
