Anticyclone over the South Pacific by Rosetta

Monday, November 16, 2009
Cloud structures over the South Pacific, seen with the OSIRIS Imaging System’s narrow-angle camera on 13 November at 06:48 CET.

This false-colour composite was generated from the orange, green and blue optical colour filters of the anticyclone visible close to the centre of the image below. This filter triplet depicts a portion of the scene below with five times the resolution.

Taken three minutes before the image above with the Imaging System’s wide-angle camera on 13 November at 06:45 CET, the image is shown in a logarithmic scale to bring out details in the varying light intensity. As a result the scene looks roughly the same as the human eye would see it.
