In this talk the speaker will address the constraints of follow-up of the electromagnetic (EM) counterparts of Gravitational wave sources and the possible ways to overcome those constraints. Various gamma ray burst (GRB) detectors, and more notably the ground–based gravitational wave detectors, typically have large uncertainties in the sky positions of detected sources. Searching these large sky regions spanning hundreds of square degrees is a formidable challenge for most ground–based optical telescopes, which can usually image less than tens of square degrees of the sky in a single night. We present algorithms for optimal scheduling of such follow–up observations in order to maximize the probability of imaging the optical counterpart, based on the all–sky probability distribution of the source position. Our algorithms are applicable for follow–up of other transient sources with large positional uncertainties, like Fermi–detected GRBs, and can easily be adapted for scheduling radio or space–based X–ray follow-up.
