Montage of four images taken by Rosetta's navigation camera (NAVCAM) on 18 October 2014 at 9.8 km from the centre of comet 67P/Churyumov–Gerasimenko. In this orientation, the larger lobe of the comet is to the left, the smaller lobe to the right. The image highlights the features of the comet’s neck, including the active region. The four images were taken in sequence as a 2×2 raster over a short period of about twenty minutes, meaning that there is some motion of the spacecraft and rotation of the comet between the images. The images have been cleaned to remove the more obvious bad 'pixel pairs' and cosmic ray artefacts, and intensities have been scaled. The individual image frames and more information is available via the blog : CometWatch – 18 October.
