The peak of the Leonid meteor shower will be Nov. 17 and 18, and it looks like a very favourable year for this sometimes huge shower. There will be a new moon, making perfect viewing conditions unless the weather is bad.

Mars is moving into the evening sky. Look low down in the east after 11pm during late October and early November, then progressively earlier as winter wears on until, by Christmas, it's rising at about 7.30pm and is well up in the east by 9pm. People talk about Mars being red, but it's more of a salmon pink colour. It is less bright than Jupiter, but still brighter than most stars.

Jupiter dominates November skies

Jupiter dominates the evening skies of November. As evening twilight darkens, Jupiter will be found shining brightly, high in the southern sky. Viewing Jupiter through a telescope will reveal its four largest moons and red-coloured bands on its surface.

Look out for meteors, comets, the northern lights and satellites

Expect enhanced numbers of meteors on and around 17 November, when the Leonid meteors occur (about one every 10 minutes under average conditions), 14 December with the Geminids (one every minute or two) and 4 January with the Quadrantids, again one every minute or two.

For November, the Moon will be full, the Hunter's Moon, on Nov. 2, so the first two weeks of the month will thus find the Moon waning and not visible in the evening sky. The last quarter moon passes three degrees south of Mars on Nov. 9; the waning crescent moon passes seven degrees south of Saturn on Nov. 12, and a thin waning crescent lies six degrees south of Venus on the morning of the Nov. 15, with the new moon on the 16th. The last two weeks of November finds the moon waxing in the evening sky, with the waxing crescent passing 3 degrees north of Jupiter on Nov. 23, then reaching first quarter phase and appearing almost overhead at sunset on Nov. 24.

This month, we have two meteor showers, the Hunter's Moon and Jupiter dominating the evening skies. But let's talk of the stars first.
Along the Zodiac, from east to west, you can now observe the constellations Taurus, Aries, Pisces, Capricornus and Sagittarius. Just below Aries the Ram, enjoy the brilliant constellation Cetus the Whale, with its reddish, super giant binary star Mira, which will vary in brightness over successive nights. Note that the tail of Pisces the Fish points directly to Mira. Though summer has already given way to autumn, the well-known asterism of the Great Summer Triangle is still visible in the western skies. The Great Square (Pegasus) is just overhead.

The northern Taurids and southern Taurids started to become active about October 1st, but do not reach maximums until early November. Both have fairly slow meteors, with the northern Taurids velocity at 29 km per second, and the southern at 27 km per second.
The Taurids produce bright slow moving orange fireballs.
At maximum in November, both showers will peak at about ZHR rates of 5 meteors per hour.
The Southern Taurids will peak around the 5th November and the Northern Taurids the 12th November. Both these meteor showers are part of the Taurid stream which in turn has been associated with Comet Encke.
