Software SONNE.EXE

Last Update: 2020/11/12

Software SONNE runs on all new(er) Windows systems up to Windows 10   (64-bit-systems too). Additionally to earlier versions it calculates and constructs more altitude dials and cylinder dials. The help files are changed to chm-format which is preferred and supported by the newer Windows systems. It's language is German or English. The language can be selected in the help-menu. In many cases a click on the right mouse-button shows a popup-menu in the same language. A Photo Gallery in the start window shows the different sundial types which are calculated by SONNE. 

The calculations are done for any reference year between 1300 and 2500 and for all latitudes and longitudes. The transition to the Gregorian Calendar in Oct. 1582 is considered.

For Output all constructions are displayed on screen or can be printed on any printer installed in Windows or saved as HPGL-files (*.plt) or dxf-files (for AutoCad, DeltaCAD,...).  The printed output can be adapted to the actual page format of your printer.

The program computes
*  the time of sunset and sunrise, moonset and moonrise and twilight (civil, nautical or astronomical)
*  with time as input the position of the sun (azimuth and altitude)
*  with azimuth as input the time of this sunposition
*  the Equation of Time (EoT).
*  tables of the declination of the sun or of EoT for any reference year (between 1300 - 2500).
It is possible to printout all results and to save the tables as text files.

The program constructs for the given geographical position (longitude and latitude)
*  horizontal sundials
*  vertical, inclining and reclining sundials (for any declination)
*  cylinder sundials (shepherd's dials, azimuthal cylinder dials, cylinder dials with polar style )
*  quadrant sundials (different types, also Gunter's Quadrant) and 2  altitude sundials by Habermel with a new "Decliner version"-
*  azimuthal sundials (azimuthal spider dial, stereographic dial, horizontoscope)
*  "umbrella dials" (specific type of bifilar dials)
*  horizontal altitude sundials ("Basho Hidokei")
*  (simple) ring sundials (farmers rings), now for low latitudes and tropics(!) too
*  compressed sundials by F. Sawyer (... more)
*  since vers. 5.9 the "Sawyer Decliner, Type 1 and 2", a new idea for portable vertical sundials indicating local mean time.
*  mean time sundial by H. Hollander (... more).
*  graph of equation of time for years from 1300 to 2500
*  sun path diagrams for years from 1300 to 2500. Display in Caretesian (x/y) coordinates or in polar coordinates.
    Additiionally horizon profiles can be calculated and included.
*  Furtheron time of sunshine on any plane (inclining and/or declining) is calculated (together with the Cartesian sun path diagram).
*  overlay of coast lines in horizontal, vertical, inclined and compressed sundials (in 'Expert Mode' only) (... more)

Type of lines computed:
*  hour lines for local time (mean and apparent)
*  time of zone meridian
*  temporal hours
In all types the time of start and end and the time interval can be selected.

In horizontal / vertical / inclining sundials, in "umbrella dials"  and some types of cylinder dials it is possible to show additionally
*  Babylonian hours
*  Italian hours
*  Lines for the sun's altitude
*  a table with the angles of the hour-lines for true solar time
Also the start time, end time and interval of these lines can be fixed.

In horizontal / vertical / inclining sundials and in umbrella sundials it is also possible to printout the coordinates of the constructions. Instead of sending the coordinates to the printer you also can send all data to an ASCII-text-file.
