This four-image mosaic comprises images taken from a distance of 94.3 km from the centre of Comet 67P/Churyumov-Gerasimenko on 26 February. The image resolution is 8.0 m/pixel and the individual 1024 x 1024 frames measure 8.2 km across. The mosaic measures 14.6 × 14.7 km.

Four image mosaic comprising images taken on 26 February 2015 by Rosetta’s Navigation Camera (NAVCAM). 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.

In this slant view, the comet’s large lobe is on the right, and the small lobe on the left.

On the left, the image is dominated by the cliffs of Hathor with hints of the smooth Hapi region, both on the comet’s neck. Moving towards the right, we see most of the Ash region on the large comet lobe and, on the underside, the Imhotep region with its constellation of boulders. Indication of activity is also visible in the upper part of the image.

We prepared an annotated view of today’s CometWatch to help you find your way around the image. You can also find regional maps of Comet 67P/C-G here and here.
