Anticyclone over the South Pacific by Rosetta

Rosetta’s OSIRIS imaging system spotted an anticyclone over the South Pacific on the morning of 13 November. The images show the scene roughly as a human eye would see it.

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.
