Useful and up to date information on eclipses can be obtained from the web
site of the Mount Suhora Observatory, near
Krakow, Poland. The site is called '
An Atlas of O-C
Diagrams of Eclipsing Binary Stars'.
If you click on ' Table of Contents' you will go to a constellation page.
If, for example, you click on ' Cas' you will see a
list of all the EBs in Cassiopeia. Click on the second star 'RZ' and you
will open pages devoted to RZ Cassiopeia, a well known bright EB system. The
pages include links to references in the literature and a reference to '
current minima and phase'. Clicking on that reference will take you to
a page that lists the minima for the next seven days from the time of
looking at the site.
The light elements recorded on the ' current minima and phase' are either
the latest elements in the literature or the latest
submitted to Krakow privately. Sometimes the latest elements can be years
old if an EB system is not observed frequently.
The times of minima can be well out. On one occasion I observed a minimum
which was seven days out. The ' latest' elements in that case had been over
twenty years old.

contact if
you have any queries about the Krakow database.
