N2 - We consider possible ways to explain the issue of excessive noisy transit timing variation (TTV) observed for severaltransiting exoplanets. In particular, for HD 189733 b we find a TTV jitter of ∼ 70 s that cannot be easily explained by asimple model. A possible cause can be the effect of photospheric activity structures on the derived transit timings. Basedon our systematic search of 1598 transit lightcurves for 26 targets, we found 109 potential spotcrossing or facula-crossingevents. However, this rate appears too low to explain the observed TTV excess, espicially for HD 189733.
