We consider the magnetic reconnection process in the current sheet within the framework of the time-dependent MHD model for a localized reconnection region. The model describes the disturbances of the ambient plasma from the accelerated plasma flows produced by reconnection. On the basis of the model we develop a method to determine the reconnected magnetic flux and center of the reconnection region from remote measurements of perturbations of magnetic field and plasma velocity under influence of such flows. The method is applied to the observations in the magnetotail of the Earth.
