16 November 2009

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. It depicts a portion of the scene below with five times the resolution.

Taken three minutes before the image above, this 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 it would appear to the unaided human eye.
