  Conjunction (astronomy) - Wikipedia, the free encyclopedia
In an inferior conjunction, the superior planet is "in opposition" to the Sun as seen from the inferior planet.
The terms "inferior conjunction" and "superior conjunction" are used in particular for the planets Mercury and Venus, which are inferior planets as seen from the Earth.
A planet (or asteroid or comet) is simply said to be in conjunction, when it is in conjunction with the Sun, as seen from the Earth.

 Chronic Conjunctivitis -- Recommendations and Resources   (Site not responding. Last check: 2007-11-06)
Conjunctivitis is an inflammation of the conjunctiva (the outermost layer of the eye and the inner surface of the eyelids), often due to infection.
Viral conjunctivitis is due to spread by aerosol or contact of a variety of contagious viruses, including many that cause the 'common cold', so that it is often associated with upper respiratory tract symptoms.
In linguistics, a conjunct is an adverbial that adds information to the sentence that not considered part of the propositional content (or at least not essential) but which connects the sentence with previous parts of the discourse.

 The Star of Bethlehem
This leads to a discussion of a different astronomical event that may be associated with the "new star" (a comet) recorded by the Chinese in 5 B.C. The Chinese would not have distinguished a comet from a nova since all they recorded was something new in the sky that was temporary.
In the early 17th century the great astronomer and Christian, Johannes Kepler, calculated that a triple conjunction of Jupiter and Saturn had occurred in 7 B.C. While Kepler did not believe this to be the actual Star of Bethlehem, it may have alerted the magi to the coming star.
In this discussion, I have considered a nova, a comet, and a triple conjunction of the planets Jupiter and Saturn as the Star of Bethlehem between 7 and 4 B.C., and none have seemed to be satisfactory.

 Astronomy Answers: 21 December 2012   (Site not responding. Last check: 2007-11-06)
On exactly 21 December 2012 there is a certain special astronomical conjunction that is so rare that it doesn't repeat for a long period of time (centuries, or even millennia) before or after that date.
Because of the conjunction, special phenomena are to be expected in the sky or on Earth on 21 December 2012.
Most calendars attempt to follow one or more astronomically determined periods, such as the seasons or the phases of the Moon, but those periods are not a whole number of days long and are not equal either to some fixed ratio of whole numbers.

 Zoom Astronomy Glossary: C
Conjunction is the apparent close approach of a planet to the Sun (or another planet), from the point of view of an observer on the Earth.
A planet is in conjunction when the Sun is exactly between that planet and the Earth or, for Mercury and Venus (the two inferior planets), when that planet, the Sun, and the Earth are lined up.
During conjunction, a planet cannot be seen from Earth (unless it is in transit); it is either behind the Sun or is lost in the glare of the Sun.

Three conjunctions of Jupiter with Regulus, the brightest star in the constellation Leo, the lion, and located between the lion's feet.
Martin sees this conjunction as having the same significance as the one of 12 Aug 3 BC, and suggests it was this 17 June conjunction that sends the Magi on their way, arriving in Jerusalem about December 25.
The rare close conjunction of Jupiter with Venus in Leo, almost exactly the same distance East of Regulus as the earlier 12 August 3 BC conjunction was West of Regulus.

Conjunction of the Moon and planets is often determined with reference to the Sun.
Astronomers have estimated that the universe could contain 40 to 50 billion galaxies.
In 2002, a galaxy discovered by a team of astronomers led by Esther Hu of the University of Hawaii was determined to be the most distant object ever observed—13.6 billion light-years away.

 Original Calendar For Our Day
The astronomical conjunction occurs when the center of the sun, the center of the moon, and the center of the earth are exactly lined up along the same earth longitude.
The astronomical conjunction occurs approximately half way between, when the center of the sun, the center of the moon, and the center of the earth are exactly lined up along the same earth longitude.
But believers in either theory, whether they figure the month starts one day later than the conjunction or one day earlier than the conjunction, will find that there is no year between 24 and 33 AD which would have a Wednesday Abib 14 when their new moon date is not that of the astronomical conjunction.

 Glossary   (Site not responding. Last check: 2007-11-06)
Conjunction is a term used to describe the situation where two or more objects are close to each other in the sky.
In the daily rotation of the celestial sphere, an object is said to culminate when it reaches its highest point in the sky.
These objects are given Messier Numbers, a number preceeded by the letter M. This catalogue of 103 objects, (extended later by other astronomers) comprises of the more prominent deep sky objects visible from Northern latitudes.

 True Conjunction vesus Molad
The true conjunction occurs the instant the sun and moon (not the earth) come into conjunction and when the sun's light strikes the face of the moon at an angle which makes it not visible to us on the earth.
"Astronomical Tables of the Sun, Moon, and Planets" by Jean Meeus, states in section 4 page 14, "September 20 at 17:02 is the true conjunction of the new moon phase." "Moon Times" by Zephyr Services for Computers, calculates the conjunction of the new moon phase for September 20 at 17:04.
According to the Astronomical tables the new moon in Jerusalem is September 20th at 20:04 PM and the molad (Jewish calendar calculation) is September 21st at 0655 AM, that is about 11 hours difference between the true astronomical conjunction and the molad.

This stage is called "Conjunction " or "Astronomical New Moon" (not to be confused with the "New Moon" referred to in Jewish literature which astronomers sometimes call "Young Crescent Moon").
When the moon passes between the sun and the Earth (Astronomical New Moon) its lit side faces the sun and its dark side faces the Earth, the result being that the Moon is invisible from the Earth.
Conjunction can be detected from earth during a full or partial solar eclipse.

 Karaite Calendar- Magdi Shamuel
The Astronomical knowledge and computerization of data which we have today assist us in knowing with great accuracy the position of the moon and the strength of its illumination at any given moment.
This stage is called "Conjunction" or "Astronomical New Moon" (not to be confused with the "New Moon" referred to in Jewish literature which astronomers sometimes call "Young Crescent Moon").
Among the institutes and sources we consult are the Astronomical Data Service in Colorodo Springs, Colorodo (which produces an Astronomical Almanac specially for the Karaite community in Israel), the South African Astronomical Observatory, and the magazine Sky and Telescope.

 Date of the Vedas : Inquiry not Proper from the Chapter "The Vedas", in Hindu Dharma : kamakoti.org:
Modern historians have adopted chiefly two methods to determine the date of the Vedas: the first is based on the astronomical references in the scriptures and the second on the morphology of the language of the same.
The date of the Vedas, fixed at 6000 B. or so, is based on an astronomical conjunction mentioned in them.
Conjunctions similar to the one on the basis of which the date of 6000 B. has been arrived at must have occured not only before the present creation, but even far far earlier.

 The Structure of the Chinese Calendar
A dark moon occurs when the Sun and the Moon are astronomically conjunct (or more exactly, when either the Moon's center lies on the line joining the centers of the Earth and the Sun or the plane defined by the Sun, Earth and Moon is perpendicular to the Earth's orbital plane).
A lunation begins at the dark moon (astronomical conjunction of Sun and Moon), and the next dark moon marks the beginning of the next lunation.
The astronomical solar year is divided into 24 equal parts known as "solar terms" (each about half the time of a lunation).

The difference between the period of the molad and the above given astronomical value of the mean lunar conjunction is 0.0000 052 827 days per mean lunar period.
Because of the constantly widening gap between the time of the molad and the time of the astronomical mean conjunction, as well as the unknown value of the time of the Hebrew calendar's first molad, it is very difficult to suggest the geographical location over which any molad takes place.

 User Manual for the Lunar Calendars and Eclipse Finder software
To put it briefly, astronomical Julian days correspond to 24-hour periods which begin at noon GMT, with 0 AJD beginning at noon on -4712-01-01 in the Julian Calendar, whereas chronological Julian days correspond to 24-hour periods which begin at midnight GMT at the start of -4712-01-01 Julian.
An astronomical Julian date is independent of location on the Earth, since it is always relative to the prime meridian of zero degrees.
Thus the times displayed for astronomical phenomena (such as full moons and eclipses) should be close to the times observed (or, for past events, would have been observed).

That is two days later than the conjunction of the sun and moon, which occurs at 9:54 PM Jerusalem time on September 28th (the day starts at sunset).
Some may question why the conjunction date is not determined according to the local time of conjunction instead of using the date of the conjunction at Jerusalem.
Let's use the year 2003 as an example to explain the chart: From Chart A-1, the time of conjunction and the Molad Tishri are only 43 minutes apart, so Trumpets would be expected to fall on the same day by either method.

This conjunction of events led to the marking of the new year coincident with this "magical rebirth" of Sirius, the Nile and Isis.
The metaphor is astronomical, hydraulic, and sexual, and it parallels the function of Isis in the myth.
Modern astronomical calculations confirm that the average length of the tropical year, when measured from the Spring Equinox, is 365.2424 calendar days (to the nearest ten-thousandth of a day).

As reported above, a committee was formed to act in the transfer of ownership of the Astronomical Journal from the Dudley Observatory to the Society, and to formulate the general policy of the Society in regard to journals and publications.
The meeting of the Society was followed by a three-day symposium on astronomical spectra, under the auspices of the Yerkes Observatory, as part of the program of the semi-centennial celebration of the University of Chicago.
This meeting also made astronomical history because Henry Norris Russell himself gave the first Russell Lecture on "A Study of Eclipsing Binaries." Harvard University was the recipient of a portrait of Harlow Shapley commemorating 25 years of his Directorship of the Harvard College Observatory.
