December 2011, Stars over Wollumbin, our Southern skies


December: get out your night goggles to watch some magnificent sky-walkers:

Jupiter, in the East, and Venus, in the West, are King and Queen of the night.

Mercury is hiding again, between Earth and Sun, for most of this month

Mars is becoming brighter and is more elevated above the horizon

Saturn rises low in the South-East before sunrise, elusive but visible

Other events

~ Meteors Showers, Geminid and Ursid ~ a Total Lunar Eclipse on December 10/11 ~

*MERCURY, in retro motion in Tropical Sagittarius since November 23,  is changing from Evening to Morning Star, moving from the Western sky after sunset to the Eastern sky before dawn, after forming an Inferior Conjunction with the Sun on December 4.

Mercury will remain invisible until the end of December, re-emerging  in the South-East after December 20. On December 22/23 it could be easier to spot him (-0.4 magnitude) because of his vicinity to the tiny Balsamic Moon (two days before New Moon)  and also his alignment to the star Antares (alpha of Scorpio constellation).

VENUS: Venus is becoming brighter every day, also more available for observation because she will remain longer in the western sky after sunset.  Her magnitude will be around -3.9 throughout the month.

Venus and the tiny Crescent Moon (two days past New Moon) will appear very close in the evening of December 27.

Venus will reach her maximum brightness at the end of April 2012 (-4.5 magnitude), her maximum elongation or longitudinal distance from the Sun expected at the end of March.

*MARS: it will be easier to spot Mars this month, rising in the East a bit earlier every day. The Red Planet is also becoming brighter, from +0.7 to +0.2 magnitude. mars will be already well above the Eastern horizon by month’s end. He will remain relatively close to the two major stars of Leo constellation, Denebola and Regulus. 

On December 18 the last Quarter Moon will transit in the vicinity of Mars, in the East, from one am until sunrise. providing a bright clue to spot Mars.

JUPITER: as it gets dark in the evening Jupiter can be observed already high above the Eastern horizon this month. He is very bright, at around -2.7 magnitude.

The Giant Planet is rapidly moving North-West, setting earlier as December advances, between two and three am at the start of December and  just after midnight by the end of the month.

Jupiter is transiting against the backdrop of Cetus (the Whale constellation). He will be caught up in the Sun’s glare in mid-May 2012.

On December 6 and 7 the Waxing Gibbous Moon will be visually close to Jupiter for good part of the night.

In December Saturn makes his return to visibility, appearing higher above the Eastern horizon before sunrise, rising in our mid-southern latitudes about 3 am.

In early April 2012 Saturn will reach his maximum elongation (distance) from the Sun and so also its greatest brilliance (+0.2 magnitude). In the month of December Saturn will shine at +0.8 magnitude only.

Saturn will still be transiting near the the alpha star of Virgo, Spica, the ear of corn in the maiden’s hand. On December 21 the Waning Moon will be aligned to both Saturn and Spica,  in the East before sunrise.

Other major astronomical events in December

A Total Lunar Eclipse in the Tropical Sign of  Gemini is on the cards for the Full Moon of December 10/11 (depending where you are in the world).

This Eclipse will be visible in its totality in most regions of Russia, the whole of Asia, including South East Asia, in China, Japan, the two Koreas, Indonesia, Papua New Guinea and Australia. It will not be visible from South America or Antarctica, and only partially from Europe, Africa, Mexico, North America and parts of Canada. 

The Nasa site discussing this Total Moon Eclipse can be found HERE.

Meteors Showers are expected this month too, the Geminid and the Ursid. The Southern Hemisphere will be ideal to watch the first one, while the second will be visible only for people North of the Equator.

The Geminid will reach its peak on December 13,14 and 15, but some of its meteors could be glimpsed between December 6 and 19. Unfortunately the big Waning Moon (Disseminating Phase, after the Full Moon on December 10) may conceal many of its shooting stars (up to 80/120 per hour! One of the best meteors showers of the year). The spectacle will be worth the effort of rising early though, especially if you live away from city lights.

The constellation of Gemini, from which this shower radiates, rises before midnight in mid-latitudes in the Southern Hemisphere, so there would be many hours of opportunity for observation. The shooting stars will appear to generate in the vicinity of Castor (with Pollux, one of the Twin stars of the constellation Gemini), situated just below the Moon for southern observers. These meteors actually originate from the Asteroid Phaeton, an unusual occurrence because most showers come instead from comets.

The Ursid meteors shower (visible only to Northern observers), will have the advantage of a darker sky, its peak occurring two days before New Moon, on December 22 and 23. The shower itself goes on from December 17 to 25. The Small Bear or Little Dipper constellation, the place from where this shower radiates, is a circumpolar constellation, meaning that it does not rise above the horizon sufficiently in southern latitudes.  This shower has less meteors than the previous one, 20-15 per hour, occasionally more. It originates from a comet called 8P/Tuttle.

June, the month to observe six members of our Solar Family


~ Jupiter at dawn in the eastern sky ~ Mercury, just emerged from darkness, low on the eastern horizon, below bright Jupiter ~ Venus in the western evening sky, for a couple of hours after sunset ~ Mars and Saturn in the North-West at dusk and through the night ~ With a pair of good binoculars we could even spot far away Uranus close to Jupiter in the eastern sky before sunrise ~


MERCURY has re-appeared as a Morning Star, very faintly at first, at the end of May. It will remain visible until mid-June, but very low in the eastern horizon in the pre-dawn sky, below much brighter and more elevated Jupiter, reaching its Superior Conjunction with the Sun on June 28.


VENUS will trace her bright course between the Twin Stars Castor and Pollux (alpha and beta of Gemini constellation) until mid-June, setting with the Beehive Cluster in constellation Cancer by June 19 (find snapshots in the June Calendar of Observable Events, below).

Our Sister Planet will remain the beautiful Evening Star until October 2010. In June it will remain around magnitude -3.9 (its maximum being -4), and also spend more time in the night sky, setting at 8 pm, three hours after the winter Sun (in Southern Latitudes), by the end of June.

The Evening Star’s incarnation of Venus represents a collective opportunity to become more self-reflective, acknowledging our contribution to any relationship issues we may be experiencing. The Goddess of Love is looking deeper into our hearts and show us the way to a less self-centred and more aware kind of loving, (see also Venus in Cancer  post).


MARS‘ light keeps diminishing this month. You can spot Mars in the evening in the North-West, relatively low above the horizon,  reddish in colour, rising in daylight and setting  just before midnight in mid-June. It will be easily spotted on June 6/7 when it will conjunct Regulus, alpha Star of Leo, and, again, on June 16/17 when it will be close to the Waxing Crescent Moon (find snapshots in the June Calendar of Observable Events, below).


JUPITER, after emerging from the glare of the Sun in March, is now a very bright star, rising at midnight and very conspicuous in the east until sunrise, with the backdrop of the Pisces constellation. By the end of June Jupiter will rise at midnight. Jupiter will become brighter and brighter as the year advances, reaching its greatest brilliance in its whole 11.8 years cycle just in time for the Libra Equinox 2010 (September 21). This is due to the fact the giant planet will reach its perihelion, closest position in relation to the Sun, in March 2011.


There is a companion to Jupiter in the pre-dawn sky, though invisible, so you will need a good pair of binoculars to spot it, 0.4 degrees above Jupiter. It is giant Uranus, spinning at right angle to everyone else, a bluish/green star-like object. Jupiter is -2.4 magnitude and Uranus at 5.8, dim but still the brightest object in the vicinity of Jupiter.

Jupiter and Uranus are conjunct for the first time in nearly 14 years on June 9, and they are nearly as bright as they can be, their opposition from the Sun getting closer. It will be exact on September 22, just as the Sun prepares to enter Tropical Libra (Spring-Autumn Equinox), opposing them only five hours apart from each other. Jupiter and Uranus meet cyclically (synodic cycle) every 13.7 years. This time they are playing a prolonged duet, though, meeting twice in 2010 (June 9 and September 22) and a third time on January 2, 2011. This is a rarer opportunity for the energies of these planets to blend for a sustained period, so exerting a greater overall influence over the affairs of the whole year. The last time Jupiter and Uranus met three times was in 1983, 27 years ago.

Animation of the triple conjunction of Jupiter-Uranus in 2010/11, from Martin J.Powell astronomical site, can be found HERE.


By the end of June Saturn will rise around midday and set around midnight. Saturn emanates a yellowish light, easily spotted between Regulus of constellation Leo and Spica of constellation Virgo, not far from Mars.Like Mars, Saturn also is becoming dimmer this month, around  +1 magnitude, moving away from the Earth at an angle that will cause its rings to become thinner, reflecting less sunlight.

The Moon will be conjunct Saturn on June 18 (find snapshots in the June Calendar of Observable Events, below).


Full Moon in Capricorn, Lunar Eclipse, June26

A Partial Eclipse of the Full Moon is due on June 26. It will happen in the Tropical Sign of  Capricorn, with the Sun in the opposite Sign of Cancer. I re-post here the article I wrote concerning this Eclipse in the 2010 Forecast post (June to September):

The Eclipses, once again, accompany the change of season, a significant fact that will make their influence more marked and also longer lasting.

The Capricorn Lunar Eclipse is Partial, visible after sunset from Australasia, and before sunrise in western South and North America.

The Moon, central to the whole interpretation, is transiting in close proximity to Pluto in Capricorn, separated from the position of this planet, as projected on the ecliptic, by a mere 0 degrees and 41 minutes of longitude. The Sun then is of course exactly 180 degrees away from the Moon and also Pluto. Even by itself this configuration would heighten the intensity of the ecliptic Moon, but there is much more. Mercury is in Cancer with the Sun on the day, while Jupiter and Uranus, still conjunct in Aries, are 90 degrees away from both Sun and Moon; while Saturn in Virgo, opposite to them, is also in a wide 90 degrees angle to Sun and Moon. This configuration is known as a Grand Cross, usually connecting four celestial bodies, but, in this case, linking instead seven: Sun, Moon, Pluto, Mercury, Jupiter, Uranus and Saturn.

Grand Crosses are tough, tight knots, forcing planets to work together, especially problematic if difficult planets are involved, as here are Saturn, Uranus and Pluto, heavy weights of the Zodiac. This Eclipse seems to draw attention and energize the knotty transits coming into activity during this season, the squares and opposition of Saturn to Pluto and Jupiter-Uranus respectively; more about these specific transits later. Some intensely emotional events can be the result of such a configuration corresponding with the time of an eclipse, because the combined forces of Jupiter and Uranus in Aries will create a fierce opposition to the might of Saturn in Libra and Pluto in Capricorn, also challenging each other: a time of quickening, a protracted labour inducing the birth of the New (a forceps birth rather than a gentle water birth). Unavoidably astrologers would notice the similarity between this event and the last lunar eclipse of 2009 (or first eclipse of 2010, depending where you were at the time), the one that preceded the Haiti and Chile’s disasters. The Sun and Moon were then placed in the Sign each other occupies in the June eclipse, on opposite hemispheres. The Sun was separating from a conjunction to Pluto and both Sun and Moon were widely square Saturn in Libra. But there is a great difference too.

All Eclipses are grouped under one specific number, known as their Saros number. A Saros group begins with a particular eclipse; other eclipses follow, at an interval of 18 years approximately, all falling around the same degree of longitude.

So, for instance, the Lunar Eclipse of June 26 2010 belongs to the Saros number 120. This group of Lunar Eclipses began with one that took place on October 5, 982 AD, close to the beginning of the last Millennium. The Eclipse that began a series is said to give its colour, tone and vibration to the lot of them. Therefore it is very important to study the first Eclipse of a Saros series to get a feel of what we are dealing with. This first eclipse of the series shows a highly charged Horoscope, but also one with many redeeming factors. The Saros number of the December eclipse instead began with an extremely difficult eclipse in 1000 AD, showing more clearly the potential destructive nature of all the following eclipses of the same number.

Information and pictures to make you better acquainted with your southern night sky

The different lighting of some of the pictures is due to the time the snapshots of the Planetarium were taken.



JUNE 6: the Waning Moon, just past the Last Quarter Phase, will join Jupiter and invisible Uranus in the pre-dawn sky. The snapshot of this event was taken looking East, just before 6 am.

JUNE 6 and 7: Mars is today and tomorrow very close to the Star Regulus, the little King in the constellation Leo. This is a great colour contrast, with red Mars and white-blue Regulus.

The snapshot of this event was taken looking toward the North, at around 7 pm. In ancient times this conjunction would spell the violent or sudden  death of a king or ruler.

JUNE 7: Venus is setting very close to Castor, one of the Gemini Twin Stars. While Mars is s still very close to Regulus, the Little King Star (alpha of Leo constellation). A great time to observe Gemini and Leo Stars.

Below is a snapshot of this event, looking toward the West around 6 pm.

JUNE 15: Venus has now moved higher than Castor and Pollux, the Twin Stars, but the tiny Crescent Moon is joyning her in a beautiful display. Here is a snapshot of this event, looking toward the North-West, just before 6 pm.

JUNE 17: the Moon will become conjunct Mars and Regulus tonight. This snapshot was taken looking toward the North-West, just before 7 pm.

JUNE 18-19: the Moon will be close to the conjunction with Saturn over these two days, against the backdrop of the Virgo constellation. This snapshot was taken on June 19 around 10 pm.

JUNE 20: Venus can be seen setting in the Beehive Nebula of constellation Cancer. Here is a snapshot of this event, taken looking toward the West, around 6 pm.

JUNE 20: the Moon is just 04 degrees far from Spica, the Ear of Corn Star in the hand of the Virgin constellation.

Here is a snapshot of the event, taken looking toward the West, around 7 pm.

JUNE 24: the Moon can be oberved very close to the alpha Star of Scorpio, Antares. The snapshot was taken, looking toward the North-West, just before 8 pm.
