Ephemerides is a computer program which computes times of minima of eclipsing binary stars. The data of variable stars are read from several catalogue files. It is intended to be used off-line, no internet connection is required at run-time. The current version works in the MS Windows 98 SE, 2000, XP, Vista and Windows 7, 8.1 and 10. It is intended for visual, CCD and PE observers.
The graphical user interface is very simple and intuitive. It can be run in the two operation modes: the computation ephemerides for one specific night or the computation of ephemerides for a particular variable star and a season. It is possible to print the table of minima on a connected printer or save it to an ASCII, HTML or CSV file.
It is possible to build and use a custom catalogue file of your own variables.

Current installation package contains following catalogue files:
BRNO - B.R.N.O. project on eclipsing binary observing, see http://var.astro.cz/brno/, valid to 29. July 2018
BRKA 2005 - selection of stars from the B.R.N.O. project, now obsolete
Prosper - project, which is concerned on new or neglected eclipsing binary stars, valid to 10. Aug 2006
The BRNO catalog file was compiled using the information from the O-C gate. Because the original source does not contain some useful information, the GCVS catalog and its supplements was used to fill in the variability type, eclipse duration (D) and GSC identification.
There are also tables of predefined locations. Download the package, unpack it to the installation directory.
Locations-cz.zip - list of populated places in the Czech Republic, based on the GEONet database - updated 22. Aug 2008
Locations-sk.zip - list of populated places in the Slovakia, based on the GEONet database - updated 22. Aug 2008
Download the binary installation package (see above). Save it to your disk and start. The installation package contains simple wizard, which will guide you through the rest of the installation. It doesn't require rebooting the computer.
The electronic help is included in the installation. You can open it from the 'Start' menu or in the application main window by clicking on the button with the question mark on the toolbar. When everything has failed, please contact the author.
Run 'uninstall' program in the installation directory or open the Control panel and use the 'Install or remove program' tool.
Yes, there is a package with source codes. It's been written in Borland Delphi 7.
