Photometric follow-ups of transiting exoplanets (TEPs) may lead to discoveries of additional, less massive bodies in extrasolar systems. This is possible by detecting and then analysing variations in transit timing of transiting exoplanets. In 2009 we launched an international observing campaign, the aim of which is to detect and characterise signals of transit timing variation (TTV) in selected TEPs. 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 summarise ﬁrst results for WASP-3b with evidence for a 15 Earth-mass perturber in an outer 2:1 orbital resonance.
