Time-dependent anomalies in the microwave absorption have been studied. These anomalies are associated with transitions between different states of the vortex lattice in the case of a pinned magnetic flux. The shift of the extrema observed in the derivative of the absorbed power with respect to the field is described in terms of a flux creep.
