Fig. 1

Coronagraphic images recorded at t0, t0 + 3 min, and t0 + 6 min. The signal is intentionally saturated in the image core to emphasize the speckle signal in the halo. The Strehl ratio is ~92%. The arbitrary color scale and dynamic range (identical for the three images) were chosen to enhance the contrast for the sake of clarity. The presence of two ghosts is highlighted in the left figure.
