A search for transit timing variation — •Stefanie Raetz1, Gracjan Maciejewski2, Martin Seeliger1, and Manfred Kitze11Astrophysikalisches Institut und Universitäts-Sternwarte, Schillergäßchen 2-3, 07745 Jena, Germany — 2Torun Centre for Astronomy, N.

Photometric follow-ups of transiting exoplanets may lead to discoveries of additional, less massive bodies in extrasolar systems. This is possible by detecting and then analyzing variations in transit timing of transiting exoplanets. In 2009 we launched an international observing campaign to detect and characterize transit timing variation signal in selected transiting exoplanets. The programme is realised by collecting data from 0.6 - 2.2-m telescopes spread worldwide at different longitudes. We present our observing strategy and summarize first results for selected transiting exoplanets.
