Work in progress (not all functionality is desribed yet, for full range of functions download Trial version). Translation in progress. This document was last modified: 2008-06-26.
Aspects
Calculated aspects are:
- conjunction (0°)
- opposition (180°)
- square (90°)
- trigon (120°)
- sextile (60°)
- quinkunks (150°)
- confinis (30°)
|
- halfsqare (45°)
- 3/4square (135°)
- quintil (72°)
- biquintil (144°)
- decile (36°)
- tridecile (108°, off by default, it's orb overlaps with biseptile)
- septle (51°25'48")
- biseptile (102°51'36")
- triseptile (154°17'24")
- nonagon (40°)
- binonagon (80°)
- quadrononagon (160°)
|
Each type of aspect has a separately set orb, different for transit, comparative
and natal charts. You may select at any time, what kind of orbs are applied
to viewed chart.
Variation from standard aspect can be given in aspect table in degrees (rounded
mathematically - from 0 to 0.5 down to 0°, above 0.5 up to 1°) or optionally
- user selectable - in percentage of maximum orb.
Aspects are divided on applicational and separational. Applications and separations
are prognosed depending on objects' position and speed in the moment of chart
calculation.
Position calculation of planets and other objects
The program uses for calculation of planetary positions the Swiss Ephemeris
libraries (http://www.astro.com/swisseph/).
It uses ephemerides, which reflect planetary positions with 0.001" angular precision
- according to ephemeris D405/406, designed in JPL, Pasadena.
Planetary positions may be calculated both with help of external ephemerid
files (original DE406 or their compressed versions), or with built-in procedures
(with lesser precision than with external files). Asteroid positions are calculated
only with help of external ephemerid files.
Urania has procedures for calculation and visualisation of positions for these
celestial bodies:
- Sun, Moon and planets Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune
with help of internal files in time range 5400 BC - 5400 AD. Pluto is
calculated with built-in ephemerides 3000 BC - 3000 AD, other planets
with help of short VSOP 87 tables.
- asteroids: internal functions calculate positions of eight biggest
planetoids (Ceres [1], Pallas [2], Vesta [4], Hygiea [10], Interamnia [704],
Davida [511], Cybele [65], Europa [52]) and Juno [3].
- centaurs and Kuiper ring objects (3000 BC - 3000 AD): Chiron (2060),
Pholus (5145), Nessus (7066), Asbolus (8405) and Chariklo (10199).
For those who require other bodies directly on chart wheel, there is a
possibility of defining 12 extra objects, with help of external configuration
file (*.odf, in program package there is default file VirtObjs.odf with sample
set of asteroids and fixed stars - editable in any word processor). Internal
format serves so far:
- asteroids, centaurs and Kuiper ring objects; for each of these bodies a
correct file is required with ephemerides for Swiss Ephemeris library. Ephemerides
are included in full version of Urania distribution pack. They are also available
separately from us - contact us
please- or directly from Astrodienst company - http://www.astro.com/swisseph/.
- fixed stars (defined likewise in external file fixstars.cat)
Caution: Asteroids and comets are calculated for period 3000 BC - 3000 AD (or
longer - varying on ephemeris file version), unless position of certain bodies
can be determined only for shorter period (ex. Chiron only from about 650 AD
to 4650 AD, because of close encounters with Saturn).
Other objects
- Ascendent (Asc) and Descendent (Desc), Medium Coeli (MC) and Imum Coeli
(IC),
- Moon Nodes - average and real on ecliptics- can be displayed separately
or together in any combination,
- Lilith - average apogee of Moon orbit ("mean apogee"),
- Vertex (point near Asc - personal matters) and Covertex (point near Desc
- others involved in our life),
- Nibiru - proposition of orbit of a body known to ancients, but not yet
found by modern astronomers (proposition is roughly sketched according to
Z. Sitchin's descriptions, in details it is determined by author's own research
- still it can be a fiction).
- Hypothetic "bodies" of Hamburgian school: Cupido,
Hades, Zeus, Kronos, Apollon, Admetos, Vulkanus, Poseidon,
- Selene fictious body.
Reference systems and position of
objects in house's plane
Coordinates
Urania allows displaying of planetary positions in different astronomic reference
systems and house systems in space. It allows to determine real placement
of planets relatively to houses' corners in space, and not just on ecliptic.
It is done in accordance to definition of house systems, different than common
simplified way, which is used only for determination of houses' cusp intersection
with ecliptic. Actually calculations are done for the following systems: Krusiński,
Koch, Placidus, Campanus, Regiomontanus.
Traditional, approximate houses' display as their projection on ecliptic plane
is set as default for the chart.
Reference systems:
- ecliptic - height, width, in two variations:
- standard view - Asc exactly on the left part of wheel
- ecliptic view - 0° Aries exactly on left part of wheel
- equatorial coordinates with start in eastern point and with sense according
to other astrological reference systems, ie. with sense inverse to that of
hourly system, and different starting point (system used only in primary progressions)
- coordinates with equal houses from starting point of reference system
- coordinates using as houses the plane of first vertical
- planets in plane of first vertical (position of planets in Campanus' houses
plane)
- planets in plane of Krusiński's houses
- planets in plane of Regiomontanus' houses
- horizon in form of a wheel (optionally with aspects), in convention E-N-W-S
(east - north- west- south)
- equatorial - rectascency, declination (both with positions of Krusiński's
house cusps on equator plane - used as a way of representing planetary positions
in Krusiński's houses)
- static equatorial Zodiac - experimental plane, a result of search for large
wheel and starting point for zodiac called 'siderial'
In traditional form - as positioning of house cusps on ecliptic - the program
calculates postitions for 19-teen "house systems" (listed in historical order):
- Porphyry (II c. Vettius Valens)
- Equal houses from Asc (II c. Vettius Valens)
- Alcabitius (circa 600 Rhetorios)
- Vedic/Vehlow
- Campanus (978-1046 Al Biruni)
- Regiomontanus (1467 Regiomontanus, Bylica)
- Placidus (1602 Maginus)
- Morinus (1583-1656 J.B. Morin de Villefranche, pen name 'Morinus')
- Meridian (early 1900 David Cope, pen name 'Zariel')
- APC - Ascendant Parallel Circle (1928 L. Knegt, formulae by P.F. van Solt 1936)
- Equal houses from MC aka M-Houses (1952 Astrological Lodge)
- Natural Graduation (1953 Colin Evans)
- Topocentric (1961 Polich, Page)
- Koch (1962 Specht, Zanziger, Koch)
- Horizontal
- Neo-Porphyry (1994 Walter Pullen)
- Krusinski (1995)
- Whole Sign (1999 Robert Hand)
- Srebrzynska (2005)
- No houses

Dynamic modifications to the chart
Relocation - saving a changed record to base do
and manual change of geographic location, of selected command "Relocation" from
handy menu of "Chart" window, which displays a dialog allowing to select
a place from cities database or enter any geographical coordinates.
The geographical position of a person can be changed in realtime, as you examine
the chart. Use keystroke "Shift+arrow up/down" to
switch chart modification from time changes to longitude - lattitude changes.
Solar chart, Lunar chartand other planetary aspects
This was programmed in general as dynamic planetarias,
that means searching of any aspect between transiting planets or natal to transiting
planets (as an option in "Find the closest transit"). Searching in time
is possible both forward and backward from any user selected date and time.
Transit on a date - dynamical transit
After selection of date and time a transit chart is displayed to be optionally
a single wheel or double-wheel chart compared to the natal one. Within such
a chart user may move in time backward or forward with any selected timestep,
on all wheels.
In case of selecting comparison of progressive and transit chart or two
progressive charts, both of them are changed according to own progression
factor (in other words the date of progressive chart is aligned with date
of transit chart).
Secondary and primary progressions
A single or a compare chart is displayed with natal or transit chart.
You may make a progressive chart out of another progressive chart.
The natal data of old progressive chart is automatically assumed for calculation
as the starting point of new chart.
Display function of progressive chart can be used for contact chart.
In this case progressive charts are automatically made for both natal/progressive
source charts, from which the contact chart was made. Then the new contact
chart is calculated from the new progressive charts.
Primary progressions - chart is calculated as for secondary progressions,
then it is displayed in selected reference system
which is related to rotation of Earth.
Lists of transits, progressions and directions
Thanks to unique search module - which finds dates of transits - in time of
a single search you may select both signle searches (ie. transits to natal positions),
or multiple different ones.
For example you may search at the same time transits to natal positions and
to their dynamically calculated progressions. You can open up to 5 independent
search windows.
This allows to conveniently make a new search in a different window for
a the same or a different person, right after finding interesting events for
the previous person!
Lists are made for aspects between natal planets, transiting and progressive:
- Secondary progressions to positions in chart (ecliptic)
- Secondary progressions to positions in chart (sectors)
- Secondary progressions to secondary progressions
- Progressive secondary ingressions into Zodiac phases (signs)
- Progressive secondary ingressions into Zodiac dvadas
- Transits to positions in chart (ecliptic)
- Transits to positions in chart (sectors)
- Transits through houses to positions in chart (ecliptic)
- Transits through houses to positions in chart (sectors)
- Transits do progresji sek. (ecliptic)
- Transits do progresji prym. (ecliptic)
- Transits do tranzytów
- Transit ingressions into Zodiac phases (signs)
- Transit ingressions into Zodiac dvadas
- Jonas dates
- Transits to transits (in plane of chart sectors)
- Primary progressions to natal (ecliptic)
- Primary progressions to natal (sectors)
- Primary progressions to natal (hour wheel)
- Directions '1° = 1 year' to positions in chart (ecliptic)
- Directions 'average daily Sun motion = 1 year' to positions in chart
(ecliptic)
- Directions of solar angle to positions in chart (ecliptic)
Ingressions to houses are now a part of more general solution, as calculation
of date for any given planetary aspect to house corner on ecliptic.
- selection - which planets to which objects (natal and progressive), which
aspects;
- extra - ingressions of planets into Zodiac phases (signs) and sectors,
- changes of motion direction (retrogradation).
Sorting of events found can be set according to planets or date, with optional
display of date and hour. You can also conveniently display chart for an
event, or a comparative chart of this moment and a natal chart.
Search engine performs the calculation of dr Jonas' cycle - a list of females'
fertility days.
Combined charts
Apart from standard midpoint composite chart
there are also it's variations:
- composite chart - according to R. Hand (approximated axes/exact axes/midpoint axes),
- relationship chart - according to R. Davidson,
- sum of object longitudes from all charts- according to M. Jordan.
Astrologic clock
A chart showing actual position of axes and planetary objects on the sky:
- as a normal chart - actual view of sky
- as above, but as a contact chart for selected person - view of sky
in midpoints' relation to a given person
- comparative clock - a chart of a selected person displayed with clock
in internal wheel
- clock of two Zodiacs - two reference systems (ecliptic and sectors) displayed
at the same time on comparative wheel.
Ephemerides in tabular or graphical form.
Sophisticated database
- display of records grouped in subsets or full set at once,
- possibility of opening up to 8 independent database views - from which
each may contain any subset (or full set), indexed according to users choice,
- saving and edition of natal, progressive, directive, vector (contact) and
relational charts,
- for progressions and directions: option of saving them independent from
natal chart or automatical trace of changes made to natal chart,
- vector/relational charts may optionally automatically change after
changes made to their source (partial) charts.
Database options
Display of julian calendar day in footer (up to 6 digits after comma, where 1s = 0,00001157d).
Dates can be entered in julian or gregorian calendar, or use default option,
which automatically sets julian calendar before 15.X.1582, and gregorian afterwards.
Comments to each record can be saved in database.
You can import to Urania databases from Astrolog (DOS) by Chwiszczuk and Arański, natal records from program Mandala 3.1 (DOS) by Dariusz Walicki, natal records from ZET database.
