128 stars in our program by December 7, 2012.   Join the campaign !!

The new list of unsolved eclipsing systems (most of them EA-type) is available as an Excel file for easier handling. The spreadsheet includes links to available charts and additional data for all the systems. Some of the eclipsing binaries are confirmed while others might be constant stars with erroneous data points in the original databases. Main data sources are ASAS-3, NSVS and Hipparcos although some other eclipsers may be included.
The stars are ordered by brightness so you can choose your targets according to your instruments.
You can then filter them as you want.

In the news section below we will inform as soon as more stars are added (and as some are solved and thus dropped off the list) and new charts are made.

ALL these stars have no period published. The goal is to observe them as often as possible in order to detect an eclipse and thus be able to determine the elements.



NEWS*NSVS has been added to the program. It is a spotted RS system with two possible eclipses recorded in NSVS data with a range V= 10.45 - 10.61  (2012, Dec. 7).

                       *V0400 Vul has been solved by Patrick Wils using ASAS-3 data. It is a bright EA (V= 6.74 - 6.89) with total eclipses and a period of 3.239408 d. (2012, Dec. 7).



V4153 Sgr has been added to the program. It is a binocular target (V= 7.5) with unconfirmed eclipses (2009, June 23).
