We consider quantum field theory in the presence of a mirror in a curved two-dimensional space-time. It is emphasized that the formula relating the comoving flux to the proper rate of change of acceleration of the mirror is independent of the state of the quantum field. It is shown that although the total comoving flux emitted by a mirror lowered in a static gravitational field is negative, the total flux seen by any static observer is positive. This apparently paradoxical result is explained by the negativity of the static vacuum energy density swept through by the comoving observer. Indeed were it not for this static vacuum energy the total comoving flux would be positive.
