The collection of times of minima for eclipsing binaries, which is called ``Lichtenknecker-Database of the BAV'' in honour of its initiator Dieter Lichtenknecker, was made available to scientists and interested amateurs in April 2004 for the first time. It was delivered on CD-ROM. A revision (more stars, more minima) was published in January 2006. For more details see announcement http://www.konkoly.hu/IBVS/Announcements/BAVLKDB.html or BAV Mitteilungen 166.

The BAV continues its efforts in collecting observatorial results from the international community of variable star observers. The database now contains more than 130,000 observed times of minimum of 1,968 stars. It is probably the largest collection of times of minima for northern eclipsing binaries.

Now we are proud to make available the Lichtenknecker-Database of the BAV (Rev. 3.0) via WorldWideWeb for everybody. Please look at http://www.bav-astro.de/LkDB/index_e.html for the English version and http://www.bav-astro.de/LkDB/index.html for the German version.

The BAV has no rights on the stored times of minimum. They are held by the authors and observers. Nevertheless we kindly ask all users of the database to cite the official title "Lichtenknecker-Database of the BAV" in regard of the enormous efforts of all the people who contributed to it.

If you have any questions or proposals for further improvement please contact the database-administrator Frank Walter (bvbav-astro . de) .
