Abstract
For a Dirac field coupled to time-dependent external electromagnetic field we define an instantaneous (on a fixed spacelike surface) causal vacuum respecting Lorentz covariance and gauge invariance. The instantaneous particle states on this surface are then defined covariantly and connected to states at another time by a Bogoliubov transformation.
