November 2011 Sky Events

Moon Phases

Wed., November 2, 2:38 p.m. EDT

First Quarter Moon

The First Quarter Moon rises around 2 p.m., and sets around 1 a.m.

Thu., November 10, 3:16 p.m. EST

Full Moon

This is the Full Moon two months after Harvest Moon, so is usually called the Oak Moon. In Algonquian it is called Beaver Moon. Other names are Frost Moon and Snow Moon. In Hindi it is known as Kartik Poornima. Its Sinhala (Buddhist) name is Il Poya. The Full Moon rises around sunset and sets around sunrise, the only night in the month when the Moon is in the sky all night long. The rest of the month, the Moon spends at least some time in the daytime sky.

Fri., November 18, 12:09 p.m. EST

Last Quarter Moon

The Last or Third Quarter Moon rises around midnight and sets around 2 p.m. It is most easily seen just after sunrise in the southern sky.

Fri., November 25, 1:10 a.m. EST

New Moon

The Moon is not visible on the date of New Moon because it is too close to the Sun, but can be seen low in the east as a narrow crescent a morning or two before, just before sunrise. It is visible low in the west an evening or two after New Moon.

Observing Highlights

All Month, evening

Comet Garradd (C/2009 P1)

Comet Garradd continues to be a nice object in binoculars or a small telescope, an 8th magnitude comet slowly crossing Hercules.

Tue., November 1, dusk

Mercury and Venus 2 degrees apart

The first of two close encounters between Mercury and Venus this month. Mercury’s proximity to Venus makes it easier than usual to spot.

Thu., November 10, 3 a.m.

Mars close to Regulus

Mars will be just north of Regulus, the brightest star in the constellation Leo.

Sat., November 12, dusk

Mercury and Venus 2 degrees apart

The second of two close encounters between Mercury and Venus this month. Mercury’s proximity to Venus makes it easier than usual to spot. Tomorrow evening Mercury will be at its greatest elongation from the Sun.

Thu., November 17, 11 p.m. EST

Leonid meteors peak

The Leonid meteor shower, which sometimes puts on a good show, peaks at 11 p.m. EST, but more meteors are likely to be visible after local midnight.

Fri., November 25

Partial solar eclipse

Visible in southern South Africa, Antarctica, Tasmania, and most of New Zealand.


Mercury is well placed in the western sky after sunset for the first half of the month. It is very close to Venus, making it easy to spot.
Venus is low in the evening sky after sunset all month.
Mars spends all of November in Leo. It now outshines nearby Regulus and reaches 7 arc seconds by the end of the month, large enough to reveal its polar cap and dark surface markings in a 6-inch (150-mm) telescope.
Jupiter was in opposition in Aries in October 28, so is well placed in the evening sky all month. Jupiter and Venus are the brightest objects in the night sky other than the Moon.
Saturn reappears just before dawn in the eastern sky close to Spica in Virgo.
Uranus is well placed in Pisces all month.
Neptune is well placed in Aquarius all month.
