|In L'Echo d'Hermès no 23 and 24 André Vander Linden (a Belgium astrologer) presents his software 'Zodiac' with the visual for Fixed Stars.
http://www.astrozodiac.be/ Zodiac software v. 8.4
It is based on the work of Bernadette Brady, who has developed her own software 'Starlight'
Another great resource is the website www.astro.com
In the Extended chart selection - Section Special - From the drop-down menu Chart Type, select Parans according to Bernadette Brady
You can get a natal PDF report from Heliacal stars and parans according to Bernadette Brady.
Bernadette Brady re-introduced the ideas of PARANS and Matrix defines it as
“A relationship between two planets (or Fixed Stars) such that they cross one of the major angles of the chart (ASC, MC, DESC, IC) simultaneously. If this occurs by transit, it would be shortly after birth, and if by direction, at some point later in life. The technique was known to the ancients. ” A planet rising while a Fixed Star is at another angle will not have the same result. Same would apply when you look at Primary Directions.
- Donald Trump: We note the Paran "Mars rising near Regulus while Algol culminating at MC". Astrologers know that Algol is the most unfortunate, violent, and dangerous star in the heavens. If you combine Mars with Regulus and Algol, you have a trio for destruction.
Vivian Robson says in Fixed Stars and Constellations “If Mars be elevated when Algol is angular, the native will be a murderer who will come to an untimely end. The same is caused by Algol angular or with the hyleg. [Robson, p.124.]
- Brigitte Bardot: According to Bernadette Brady Alkes rising is her star at heliacal rising, symbol of a vocation, of a mission - spiritual, mystical or other - to fulfill. We also note the Paran "Mars at sunrise - Fomalhaut at sunset". The principle of the star - idealism and charisma, coupled with that of Mars - action, is a good sign of his fight in favor of animals. (quoted from Van Linden)
And here is the article of André Vander Linden - Google translate with some modifications on the astrological terms.
The practice of fixed stars still raises many questions, among others that of knowing whether to refer to their ecliptic longitudes, their right ascencions or their positions in mundo (= domitudes).
The ancients observed the sky! ... and especially noted the special configurations: a particular sky, particular destiny. In the same way that we distinguish an angular planet as dominant, the fact that a star and a planet simultaneously transited the horizon (rising, setting) and / or the meridian (culmination, anticulmination) was considered important by the ancients, but here it is a couple, a star / planet combination.
We all know the historical example of the star Sirius: its heliacal rise - time of the year when it rises shortly before sunrise - after about 3 months of invisibility, marked the beginning of the year, accompanied great festivities, and announced the near arrival of the floods of the Nile. In a given place, some stars are visible all year round (circumpolar stars in the same hemisphere as the place), others never (circumpolar stars in the opposite hemisphere), others still partially: between these two polar circles, depending on the latitude of the location, the stars are visible part of the year and / or part of the night.
As a first example, let us choose one of the so-called "royal" stars: Fomalhaut (Pisces Austral), and for Paris (48N52 - 002E20). Here are his contact details for 2013:
Right Ascension: 344 ° 36 'Variation: -29 ° 33' Zodiacal latitude: -21 ° 08 'Longitude: 04 Pisces 03
Diurnal arc in this place: 6:36 (99 °): this is the time that Fomalhaut spends above the horizon, every day.
Note first that the conjunction - in right ascension - of this star with the Sun occurs around March 3.
Co-rising: 18 Taurus26 Co-culmination: 13 Pisces17 Co-setting: 19 Aquarius31
These last three data indicate respectively the longitudes of the Asc, the MC and the Dsc at the times when the star rises, peaks, sets. Any chart drawn up for a place of the same latitude as Paris and having one of these angles at the aforementioned longitudes will see Fomalhaut passing through one of these planes (horizon or meridian).
When can we expect the star and the Sun to rise at the same time in Paris (heliacal rise)?
We call cosmic rising the moment when the Sun and the star cross the horizon at the same time. For Paris, the chart must be drawn up for 05/09/2013 at 4:32 a.m. LMT (in the figures below, the times of sunrise and sunset are all expressed in local time (LMT).
Figure n ° 1 represents the local sphere where we see the Sun and Fomalhaut rising. It is obvious that the Sun and Fomalhaut are far apart from each other, something that the chart in domitude does not allow to see. To say "Sun conjunct Fomalhaut conjunct Asc" in domitude means that they cross the horizon at the same time and at this moment.
Recall that, in their apparent daily movement, the stars describe their parallel of declination: the ellipses representing these movements are parallel to the equator. This configuration - Sun and Fomalhaut at sunrise - is called PARAN, as are all the other combinations (planet at sunrise at the same time as a star at the meridian, etc.).
Cosmic rising is a theoretical datum. Practically, to see a star appear for the first time at dawn on the eastern horizon, it must not be "too bright": the Sun must still be below the horizon and the star above. . It is not possible to calculate this exact moment, because it depends on several factors: brightness of the star, azimuth deviation from the Sun, local atmospheric conditions during the day, refractive air humidity, etc. On average, we can estimate that the Sun must be 8 ° below the horizon and the star 3 ° above.
The calculations therefore only provide the times of "true", geometric phenomena, and not those of apparent phenomena. The difference between these two phenomena can sometimes be very important (several days).
In order to fully understand what happens over the course of a year, I imagined a 24-hour clock on which 3 sectors are represented: in yellow, the diurnal arc of the Sun of the day; its counterpart in blue: night; and the green district associated with the diurnal arc of Fomalhaut. The length of the latter is constant throughout the year (6:36), the declination of the star being a factor that varies very little. By way of comparison, the declination of Fomalhaut was equal to -30 ° 09 'in 1900.
Let's start from the day of heliacal rising, and follow the chronology of the major phases. The
times of the rising and setting of the Sun and the star are mentioned in each figure as well as the corresponding date.
In yellow = day
In blue = night
In green = star
Definitions and clarifications
Some confusion may arise when reading Bernadette Brady's book (Brady's Book of Fixed Stars, Samuel Weiser, 1998) about the terms used to describe phases of visibility. Here are their exact definitions:
Heliacal rise: first day when the star is seen to rise on the eastern horizon shortly before sunrise
Heliacal set: last day when the star is seen to set on the western horizon shortly after sunset
Acronical rise: (also called "second" heliacal rise) first day when the star is seen to rise on the eastern horizon shortly after sunset
Acronical setting: last day when we see the star set on the western horizon shortly before sunrise
(Mnemonic: heliac = with the Sun, acronyque = on the side opposite the Sun).
Important note: Brady mentions on pages 20 to 40 of her book the dates of heliacal rises and sunsets (for the year 2000). What she calls HS (Heliacal Setting) is in fact, according to the definition above, the acronical setting: setting of the star when the Sun rises. In the fixed stars module of my Zodiac software, so as not to confuse him with her book, I respected Brady's convention: the HS (Heliacal Setting in French CH, Coucher Héliaque) therefore correspond to acronical setting.
Figure 2: "true" heliacal rise on 06.10.2013: the Sun rises at the same time as the star. Day, theoretical, when the star would be visible for a short time in the light of dawn: it is the beginning of its phase of visibility.
Figure 3: 06/18/2013 (40 days later): Fomalhaut rises at 1:54 am, it is dark, his rise is visible. On the other hand, his setting is not. Visibility time increases. Note that the fixed stars, because their declnations can be considered constant, rise every day 3min56sec earlier. Do the math: heliacal rise took place at 4:32 - (40 x 3min56sec, or 2h37m20s) = 1h54.
Figure 4: 11.08.2013: acronic setting. The star sets when the Sun rises. The star becomes visible all night long.
Figure 5: 11.11.2013: acronic rising. The star rises when the Sun sets. End of the full visibility period.
Figure 6: 12.31.2013: visibility continues to decrease. Sunrise invisible, sunset visible.
Figure 7 08.02.2014: heliacal setting: the star sets at the same time as the sun. The setting of the star cannot be observed (it is daylight). Beginning of the period of invisibility. Sunrise and sunset invisible. The star joins the underground world, world of the dead, the world of the living is no longer concerned by it. The star will remain invisible until his next heliacal rise on 05/09/2014 (i.e., in our example, approximately 3 months).
Figure 8 The graph below gives the longitudes of the co-rises and co -sets of Fomalhaut according to the geographic latitude, for 2014. Example: for 49 ° North, the star rises when the degree 18 ° Taurus rises, it sets at the same time as the degree 19 ° Aquarius. The area to the right between the curves, called LCC (Hidden Sunrise and Sunset), corresponds to the periods of the year when the star is invisible, i.e. when the Sun crosses the area of the sky where the star is located. However, a Sun at 18 ° Taurus corresponds to May 10 and 19 ° Aquarius to February 9 (within 1 day): it is indeed the period of invisibility of the star going from heliacal setting to heliacal rising (LCC = Sunrise and Hidden Setting).
