Jupiter and the Moon

On a cold and wonderful February night there was this lovely sight of Jupiter and the moon although there is a scarcity of articles out there on the observation -

The magnifications guys settle on the usual thrill of watching Jupiter beside the Moon however the discerning astronomer elevates the observation much,much further.

The simple rule is that when Jupiter is to the left side of the central Sun from our point of view it is an observation after twilight while when it is to the right side of the Sun it is observed just before dawn ad heading into daylight . This observation is also crucial for understanding the astronomical event behind the leap day correction as the stars move from the left side of the central Sun (twilight) to the right side of the Sun (dawn) -

The Earth as an object careering through space along with the other planets leaves behind the notion of the local horizon and what is East and what is West for the purpose of gauging orbital motion and the structure of the solar system. It is a vastly different type of astronomy that occupies celestial sphere magnification guys and the thrill they get from observing objects close to each other but it is so less ambitious and adventurous than the panoramic spectacle where objects move relative to each other and in the case of the planets around the Sun.

Unfortunately, your 'simple rule' is not so simple for the superior planets.. Right now, for example, as your link clearly indicates, Jupiter is neither to the right of the Sun nor is it to the left of the Sun, but rather Jupiter is almost exactly opposite from the Sun as viewed from the surface of the Earth, and the proof of this is that is appears to be nearly next to the full moon! Do have any doubt that the moon is about 180° from the sun when full?

You have trouble with the most basic observation as the Sun appears daily followed by the stars due to a single rotation of the planet so orbital inputs wouldn't interest you.Better go to a thread where you can be an old man in comfort with your celestial sphere observing and your stock phrases.

The simple rule is that as the faster Earth travels through space, Jupiter and all the outer planets move from a twilight appearance to a dawn appearance or move behind the central Sun.

The inner planets can go from a dawn appearance to a twilight appearance as it moves from behind the central Sun and as they are faster they move from a twilight appearance to a dawn appearance as they swing back in -

I wouldn't give a peevish old mind the credit to be able to distinguish the left and right side of the Sun as seen from a moving Earth, after all this joker couldn't figure out how the photographer took images of Venus 'below' the Sun.

You are so predictable. You have not been blessed with a gift for perspective, and obviously you didn't understand a word I wrote. You have no clue that there can be an imaginary line drawn from the Sun to Jupiter, and that the Earth occasionally is at a point along that line so that from our perspective the Sun and Jupiter are in opposite directions... that's why they call it the "opposition of Jupiter". The same thing happens for the other superior planets, too, so about every Earth year we have the 'opposition' of Mars, Saturn, Uranus, and Neptune, and for countelss other objects that orbit the Sun at a great distance from the Sun than the Earth.

It is really a very simple concept, no voodoo required, only a few working brain cells...

So tell me, oh Wise One, just where was the 'photographer' standing when he took that 'image'?

I have given you enough time and can't be expected to waste any more even though you have provided a truly homocentric view of above/below that none of the rest were willing to give.

Due to the faster orbital motion of the Earth, Jupiter will be seen to move from a twilight appearance to a dawn appearance as eventually the central Sun intervenes -

All the outer planets are lost behind the glare of the central Sun due to the fact that the Earth travels faster in its orbit hence the relevance of using twilight to distinguish the left side of the Sun from our point of view and dawn as representing the right side of the Sun. That is why the two graphics in combination provide a healthy view of the solar system and the Earth's motions as opposed to being stuck with outdated language from a geocentric era such as opposition,conjunctions, elongations and so on.

I am waiting for people to join me in the 21st century whereas you can go out into the dessert with your giant telescope and do no harm to anyone.

To get the full perspective relies on 'when' the photographer took the image for when Venus is to the left side of the Sun as it emerges from behind the Sun, moves to its widest point from our perspective before turning back in front of the Sun, those images are taken as Venus follows the disappearance of the central Sun.Likewise the photographer took the images of Venus to the right side of the Sun at dawn when Venus precedes the appearance of the central Sun.

You have spent so many years with stellar circumpolar motion and the daily motion of objects from one horizon to another that you find it impossible to adjust to a perspective many others have already done so using the phases of Venus and its size increase as it approaches our orbit in its journey around the Sun.

This insight that the outer planets will eventually move from a twilight observation to a dawn observation has gone unused as an additional affirmation using relative speeds that the Earth and all other planets travel around the Sun. While the relative speeds of the Earth overtaking the slower moving outer planets originally cracked the geocentric perspective, this new perspective is far more adventurous as it distinguishes the inner and outer planets by perspective. That is why the graphic is so wonderful as there is so much going on -

The term multitasking comes to mind for while celestial sphere observers can only manage to identify celestial objects close to each other or individually, an incomparable astronomy awaits those who can put observations in context of the Earth's motions, solar system structure and beyond.
