Comet 67P/C-G on 16 February 2015 - NavCam mosaic
Mosaic of four images taken by Rosetta's navigation camera (NavCam) on 16 February 2015 at an average distance of 226.5 km from the centre of comet 67P/Churyumov-Gerasimenko.
The mosaic has been slightly cropped and covers 37.4 × 37.2 km. The image scale is about 19.3 m/pixel.
The images used for this mosaic were taken in sequence as a 2×2 raster over a short period af about twenty minutes. Rotation and translation of the comet during the imaging sequence make it difficult to create an accurate mosaic, and there may be some spurious spatial and intensity features as a result of the mosaic-making sequence, so always refer to the individual frames before performing any detailed comparison or drawing conclusions about any strange structures or low intensity extended emission.
The image has been cleaned to remove the more obvious bad pixels and cosmic ray artefacts, and intensities have been scaled. Some contrast enhancement has been applied.
The four individual images are also available as related images in the right-hand menu.
More images of comet 67P/Churyumov-Gerasimenko can be found in the '67P - by Rosetta' collection.
