Day 7: Draconid meteor shower
The Draconids are a small, long-lasting meteor shower that only produces about 10 meteors per hour. It was created by these comet 21P Giacobini-Zinner left behind, first discovered in 1900. The Draconids are an unusual meteor shower because the best time to see them is at dusk rather than dawn like most other meteor showers.
The meteor shower occurs annually from November 6 to 10, and this year will peak on the night of the 7th. This year, the first half moon of the month will eclipse all but the brightest meteors. If you are patient, you will still be able to admire some beautiful views.
The best viewing time will be at dusk from a dark location, away from city lights. Meteors will radiate from the constellation Draco but can appear anywhere in the sky.
Day 8: Mercury reaches maximum western elongation
Mercury will reach its greatest westward angle at 18 degrees from the Sun. This is the best time to view Mercury as it will be highest above the horizon in the morning. Look for the planet low in the eastern sky just before dawn.
