True colour images of Earth as seen by Rosetta's OSIRIS camera are now available. The pictures were taken on 13 November during the swing-by, and on 15 November, as Rosetta left on its way to the outer Solar System, after the swing-by.

After its closest approach to Earth, Rosetta looked back and took a number of images using the Optical, Spectroscopic, and Infrared Remote Imaging System (OSIRIS) Narrow Angle Camera (NAC). This particular image was acquired 15 November 2007 at 03:30 CET.

The image above is a colour composite of the NAC orange, green and blue filters.

At the bottom, the continent of Australia can be seen clearly.

During the swing-by, OSIRIS observed Earth's night-side.

TRMM Turns Ten - Studying Precipitation From Space
Greenbelt MD (SPX) Nov 21, 2007
Earth: water planet. Oceans, rivers, aquifers, rain: these and many other features describe the hydrologic anatomy of Earth's thin, life-supporting layers of upper crust and lower atmosphere. How it works-that is, how water circulates, behaves, and interacts is much harder to determine.
