The Moon was imaged with the OSIRIS Narrow Angle Camera (NAC) at 07:36 CET, about nine hours after Rosetta's closest approach to Earth.
Rosetta’s second Earth swing-by OSIRIS has been designed to image faint objects, so a neutral density filter was placed in the optical path to reduce the sensitivity of the camera to one-fiftieth. The above image was acquired through the far-focus red filter of the camera (750 nanometres).
The image of Earth is targeted roughly at Greece. It was taken with the OSIRIS Wide Angle Camera (WAC) during the swing-by.
