Predictions are counted for observers located in central Europe (Czech republic): 50° north and 15° east.

Neglection rating:
1 = many observations in last 10 years, 10 = no CCD minimum in last 10 years. More information about rating.
RECOMMENDATION FOR OBSERVERS OBJECTS WITH RATING 5 AND MORE SHOULD BE OBSERVED

Astrophysical interestingness:

There are many systems, which exhibits period changes in O-C diagrams. We have highlighted them among others using small color signs (see the list bellow). Explanations of used colors is given in the picture and appears when your mous move over the sign as well.
The astrophysical interestingness has prepared L. Smelcer, 2009 according to O-C gateway. Updated by P. Zasche (2011).
