Thursday December 31 to Thursday January 7

The Last Quarter Moon is Wednesday January 6. The bright planet Venus is low in the twilight morning skies.  Jupiter and Saturn, just past the great conjunction, are low in the  twilight skies. Dimming but still bright Mars now dominates the evening skies.

The Coming Grand Conjuction of Jupiter and Saturn (Monday, 21 December)

Evening sky at 21:33 ACDST (60 minutes after sunset) on Thursday, December 17 facing west as seen from Adelaide. The pair of Jupiter and Saturn are above the western horizon close to the thin crescent Moon.  The pair are visibly closer now, and fit within a wide-field telescope eyepiece, heading for their spectacular meeting next week.

 The insets show the telescopic views of Jupiter and Saturn at the same magnification at this time.

Evening sky at 21:35 ACDST (60 minutes after sunset) on Monday, December 21 facing west as seen from Adelaide. The pair of Jupiter and Saturn are above the western horizon in a spectacular meeting.  The pair are almost impossible to tell apart and may look like a single object. The pair fit within a narrow-field telescope eyepiece field of view.

 The insets show the telescopic views of Jupiter and Saturn at the same magnification at this time.

If you have been watching Jupiter and Saturn  over the past weeks you will have seen them edge closer together (clouds willing , see images above). Over the next few days you will see then come so close that it will be difficult to tell them apart, and they will look like one object on the solstice (Monday 21 December). But before that we have a lovely sight as a teaser.

On December 17 Jupiter Saturn and the moon form a triangle with the crescent Moon very close to Jupiter. This will be an excellent sight as Jupiter and Saturn they are less than half a finger width apart with the crescent Moon just two finger-widths above. 

The trio can be easily seen together in a binocular field, and Jupiter and Saturn are visible together in wide field telescope eyepieces.

 On the 21st on the night of the solstice, Jupiter and Saturn are a spectacular 0.1 degree apart. This means that they will look like one object,a single bright planet, to most people. 

However, they will be visible together in high power telescope eyepieces, which will be a wonderful viiew (see top right illustration for a simulation of possible views). The pair are just one and a half hand-spans above the horizon at nautical twilight, an hour after sunset, so you don’t have much time to observe this and need a clear level horizon for the best views. 

Jupiter and Saturn meeting is a rare occurrence (only around every 18-20 years). This it is because it takes Saturn nearly 30 years to complete one orbit while Jupiter takes nearly 12 years, so we see Jupiter meet Saturn every 20 years. 

However, very close encounters, lees than a finger-width, are even rarer due now the orbital inclinations of Jupiter and Saturn line up. The last time such a close encounter occurred was in 1623, nearly 400 years ago. We don’t have to wait as long for the next though, 15 March 2080, although you will have to get up early in the morning. 

In 2040 and 2060 Jupiter and Saturn will be a finger-width apart, still pretty cool. 

You don't need fancy scopes or binoculars to see this, it will be terrific to the unaided eye, even from suburban skies. Look to the west from a bit before a hour after sunset and (clouds willing) the pair will be clear, the you have about an hour (17th) to half an hour (21st) to observe them.

The are best seen with a clear, level horizon lie the seen of flat land, lots of tall trees will get in the way.

If you do have binoculars of a telescope and a modern mobile phone, you should try and image the pair.  My guide for the 2019 perigee Moon may be helpful for mobile phone users, although you will have to use more sensitive exposures (typically around 1600 or 3200 ASA to keep the exposure times low below 1/8 of a second to reduce trailing, you will need to play around.). And there is a downloadable PDF guide to mobile phone astronomy at SpaceMath@NASA.

Thursday December 17 to Thursday December 24

The First Quarter Moon is Tuesday December 22. The bright planet Venus is low in the twilight morning skies.  Three bright planets dominate the early evening sky with Mars, Jupiter and Saturn making the evening twilight skies stunning. Jupiter and Saturn form a spectacular thin triangle with the crescent Moon on the 17th, followed by an even more spectacular rare conjunction when the pair will seem to merge on the 21st, the solstice.The waxing Moon is near Mars on the 23rd and 24th.

This is the first time Jupiter and Saturn have been this close in around 400 years.

Over the next few days there are a series of  bright ISS passes in the late evening twilight/early evening. The outstanding passes are when the ISS passes below or through Orion's belt (13th, all states except NSW). As well there a number of passes close to bright stars. For the morning of the Geminid Meteor Shower (14th) many locations have bright ISS passes accompanying this as well. There also might be a starlink train as well.

The following tables are from data provided from Heavens Above. Particularly impressive passes are highlighted.

When and what you will see is VERY location dependent, so you need to use  Heavens Above  to get site specific predictions for your location, a small difference in location can mean the difference between the ISS passing over a star or planet or missing it completely. As always, start looking several minutes before the pass is going to start to get yourself oriented and your eyes dark adapted. Be patient, there may be slight differences in the time of the ISS appearing due to orbit changes not picked up by the predictions. Use the most recent prediction for your site.
