What is ‘Systemic Coaching’?

Who are we as women, men or trans? Who are we in our roles, as fathers, mothers, lovers, leaders? What positions do we have, what places can we take, bearing in mind our ancestral inheritance? How can we undertake the tasks necessary to support and understand the day to day work our identity demands of us? Identity, with all its challenges and questions, must surely also be addressed within family constellations. The faculty is curious about the range of ideas and the richness of the talks and workshops that will arise during Intensive Can we also contribute to the theme of political identity?

We are looking forward to the discussion on identity theory as well as the many related topics that will be evoked. Constellations explore hidden dynamics in relationship systems, as well as the embedded laws governing the success of love. The faculty shares a deep commitment to personal integrity, openness to innovation and continuous learning through dialogue and careful observation.

Together with the multicultural community of learners, the faculty provides a variety of perspectives and interests. The Intensive is an opportunity to experience different approaches in action. It is organized to facilitate learning for people from differing cultures, with various levels of experience.

Introducing Coaching Constellations

And it is designed to help participants understand:. Participants are responsible for their own ethical practice. This requires of all of us that we limit how we use constellations to clients and situations for which we have the appropriate qualifications and experience.

History of observations

A well known map from the Song period is the Suzhou Astronomical Chart , which was prepared with carvings of stars on the planisphere of the Chinese sky on a stone plate; it is done accurately based on observations, and it shows the supernova of the year of in Taurus. Influenced by European astronomy during the late Ming dynasty , more stars were depicted on the charts but retaining the traditional constellations; new stars observed were incorporated as supplementary stars in old constellations in the southern sky which did not depict any of the traditional stars recorded by ancient Chinese astronomers.

Historically, the origins of the constellations of the northern and southern skies are distinctly different. Most northern constellations date to antiquity, with names based mostly on Classical Greek legends. Argo Navis.

Some southern constellations had long names that were shortened to more usable forms; e. Musca Australis became simply Musca. Some of the early constellations were never universally adopted. Stars were often grouped into constellations differently by different observers, and the arbitrary constellation boundaries often led to confusion as to which constellation a celestial object belonged. Before astronomers delineated precise boundaries starting in the 19th century , constellations generally appeared as ill-defined regions of the sky.

The star atlas " Uranometria " of Johann Bayer assigned stars to individual constellations and formalized the division by assigning a series of Greek and Latin letters to the stars within each constellation. These are known today as Bayer designations. Knowledge that northern and southern star patterns differed goes back to Classical writers, who describe, for example, the African circumnavigation expedition commissioned by Egyptian Pharaoh Necho II in c.

However, much of this history was lost with the Destruction of the Library of Alexandria. The history of southern constellations is not straightforward. Different groupings and different names were proposed by various observers, some reflecting national traditions or designed to promote various sponsors.

Southern constellations were important from the 14th to 16th centuries, when sailors used the stars for celestial navigation. Italian explorers who recorded new southern constellations include Andrea Corsali , Antonio Pigafetta , and Amerigo Vespucci. Many of the 88 IAU-recognized constellations in this region first appeared on celestial globes developed in the late 16th century by Petrus Plancius , based mainly on observations of the Dutch navigators Pieter Dirkszoon Keyser [38] and Frederick de Houtman.

Several modern proposals have not survived. The French astronomers Pierre Lemonnier and Joseph Lalande , for example, proposed constellations that were once popular but have since been dropped. A general list of 88 constellations was produced for the International Astronomical Union in In , Henry Norris Russell produced a general list of 88 constellations and some useful abbreviations for them.

In , the International Astronomical Union IAU formally accepted 88 modern constellations , with contiguous boundaries [51] along vertical and horizontal lines of right ascension and declination developed by Eugene Delporte that, together, cover the entire celestial sphere; [4] [52] this list was finally published in The aim of this system is area-mapping, i. Equirectangular plot of declination vs right ascension of stars brighter than apparent magnitude 5 on the Hipparcos Catalogue , coded by spectral type and apparent magnitude, relative to the modern constellations and the ecliptic.

The boundaries developed by Delporte used data that originated back to epoch B Gould first made his proposal to designate boundaries for the celestial sphere, a suggestion upon which Delporte would base his work. The consequence of this early date is that because of the precession of the equinoxes , the borders on a modern star map, such as epoch J , are already somewhat skewed and no longer perfectly vertical or horizontal. The Great Rift, a series of dark patches in the Milky Way , is more visible and striking in the southern hemisphere than in the northern.

It vividly stands out when conditions are otherwise so dark that the Milky Way's central region casts shadows on the ground. Members of the Inca civilization identified various dark areas or dark nebulae in the Milky Way as animals and associated their appearance with the seasonal rains. The Emu in the sky —a constellation defined by dark clouds rather than by stars. The head of the emu is the Coalsack with the Southern Cross directly above.
