Today’s CometWatch entrance shows a perspective of Comet 67P/Churyumov-Gerasimenko taken on 23 June, when Rosetta was 197 km from a comet centre. This singular support NAVCAM picture has a fortitude of 16.8 m/pixel and it measures 17.2 km across.

In this orientation, a tiny comet lobe points to a bottom left, and a vast lobe to a tip right. The comet’s activity, extended by picture estimate in LightRoom, is manifest all around a nucleus.

In a foreground, a picture shows tools of a Ash segment on a vast lobe, as good as providing an ambiguous perspective on a well-spoken plains of Imhotep towards a right. Parts of a vast lobe, as good as a neck and tiny lobe, are expel in shadow, and usually a tiny apportionment of a severe Anuket segment is lit. Nevertheless, a full outline of a iota can be certainly seen as a conformation opposite a disband heat of a coma.

Meanwhile, Rosetta is during around 160 km from a comet currently and is stability to fly over a segment that is suspicion to be many optimal to accept a vigilance from Philae, that is located on a tiny lobe. However, no serve signals from a lander have been perceived given 24 Jun and a goal teams are operative tough to know a situation. After clever investigate of a comet environment, Rosetta will diminution a smallest stretch to a comet during subsequent week, adult to a closest proceed during 155 km.

The strange 1024 x 1024 picture of today’s CometWatch is supposing below:
