CometWatch 22 March

This single frame Rosetta Navigation Camera image was taken on 22 March 2015 at a distance of 77.8 km from the centre of Comet 67P/C-G. The image scale is 6.6 m/pixel and the 1024 x 1024 pixel image measures 6.8 km across. The image above has been processed to bring out the details of the comet’s activity, while also emphasising details on the nucleus. The image presents another interesting view of regions previously cast in shadow, particularly on the small lobe around Hatmehit, and of the topography on the large lobe close to Aker and Khepry. (The 9 March image also offered a new view of these regions, from a slightly different angle). At the bottom right, the large lobe is casting a shadow over the broader ‘atmosphere’ around the comet. The original 1024 x 1024 image is provided below.
