Does anyone know whether the question has been asked (and answered?) regarding whether or not the SKA has the sensitivity to detect lightning (or other radio signals) from extrasolar planets? (See [1, 2] for example.) If so, one would suspect that if the lightning were relatively continuous it might be feasible to pin down certain orbits with greater accuracy. If the lightning is powerful enough one might be able to detect planets that are too small to be detected using current doppler and occultation methods. If one still detects radio signals when the known planets are behind the star then that could lead one to suspect that the picture of the extrasolar solar system is somewhat incomplete.
