What's new:

2010-08-29 : Non-linear ephemeris was implemented for transit predictions of two new transiters - Kepler-9 b and Kepler-9 c. The transit prediction should be now more accurate.

2010-08-28 : Kepler-9 b and Kepler-9 c transiting exoplanets were added to ETD
Please note, that there are VERY significant TTV (hours!), so linear ephemerides gives is a bit uncertain transit predictions. See the plots.

2010-08-24 : Five new transiting exoplanets HAT-P-20 b, HAT-P-21 b, HAT-P-22 b, HAT-P-23 b and HAT-P-24 b were added to ETD. All the stars are located in northern hemisphere.

2010-08-19 : New transiting exoplanet WASP-37 b was added to ETD.
