October 8 and 9 – Draconid meteor shower
The Draconids are a small, prolonged meteor shower that only produces about 10 meteors per hour. It is created by dust particles left behind by comet 21P Giacobini-Zinner, first detected in 1900. The Draconids are an unusual meteor shower because the best time to see it is at dusk instead of dawn as most other meteor showers. The meteor shower takes place from November 6 to 10 every year and this year will peak on the night of October 8. This year, the last half moon of the month will rise early in the morning but not too much. The best viewing time will be at dusk in a dark location away from city lights. Meteors will radiate from the constellation Draco but can appear anywhere in the sky.
October 15 – New Moon
The Moon will be in the same direction as the Earth relative to the Sun and will not appear in the night sky. This stage takes place at 00:56. This is the best time to observe faint objects like galaxies and star clusters as they will not be affected by moonlight.
October 15 – Annular Solar Eclipse
An annular solar eclipse occurs when the Moon is too far from Earth to completely obscure the Sun. This results in a ring of light around the disk of the Moon. An annular eclipse cannot see the corona of the Sun. The path of the eclipse will begin in the Pacific Ocean, off the southern coast of Canada, and will cross the southwestern United States and Central America, Colombia and Brazil. The partial eclipse will be visible across North and South America (not visible in Vietnam).

October 20 and 21 – Orionid meteor shower
The Orionids are a medium shower of stars, producing up to 20 stars per hour at most. It is created by dust particles left behind by Comet Halley, known and observed since ancient times. The meteor shower occurs every year from October 2 to November 7. The peak this year is on the night of October 21. The first half moon of the month may obscure some evening meteors, but it doesn’t affect too much. The best time to watch is from a dark place after midnight. Meteors will radiate from the constellation Orion but can appear anywhere in the sky.
October 23 – Venus reaches its western maximum ecliptic
Venus reaches its maximum eastward elongation, up to 46.4 degrees from the Sun. This is the best time to see Venus as it will be at its highest point above the horizon in the morning sky. Look for the bright planet in the eastern sky before sunrise.
October 29 – Full Moon, Partial Lunar Eclipse
A partial lunar eclipse occurs when the Moon passes through Earth’s partial umbra, or umbra, and only part of the Moon passes through the darkest region, or umbra. During this type of eclipse, part of the Moon darkens as it passes through the Earth’s shadow. The eclipse will be visible across Europe, Asia, Africa and Western Australia.
