This week’s Cometwatch entrance was taken by Rosetta’s NAVCAM on 22 Nov 2015 when a booster was 127.7 km from a iota of Comet 67P/Churyumov-Gerasimenko.
The scale is 10.9 m/pixel and a picture measures 11.1 km across. The contrariety has been easily extended to move out a comet’s activity though losing sum of a nucleus.
A distinguished active segment is clearly manifest towards a setting on a right of a iota in this orientation, tighten to a comet’s ‘neck’.
Although faint, several disband jets of activity can also be seen emanating from a Imhotep region, that is expel in shade in a foreground. Stretching a contrariety of a picture even serve will exhibit these active regions some-more clearly (but will rinse out a nucleus).
The comet iota is oriented with most of a southern hemisphere visible, confronting ‘up’. On a tiny lobe in a background, a comparatively prosaic segment of Wosret can be identified, with a transition by Sobek on a neck into Anhur on a vast lobe in a foreground.
The strange 1024 x 1024 picture of today’s CometWatch is supposing below:
