Today’s CometWatch entrance was taken by Rosetta’s NAVCAM on 21 Sep 2015, about 330 km from a iota of Comet 67P/Churyumov-Gerasimenko.

The scale is 28.1 m/pixel and a picture measures 28.8 km across. The contrariety was increasing to raise a comet’s activity; a strange picture is supposing below.

The comet is oriented with a tiny lobe to a left and a vast lobe to a right. Jets of gas and dirt are seen all around a sunlit apportionment of a iota and are quite transparent around a executive neck segment with a ejected element seen fluctuating towards a corner of a picture frame.

This week Rosetta embarked on a new arena that will take it 1500 km divided from a comet iota by 30 Sep in sequence to examine a broader scale of a coma and to examine a comet’s plasma environment. It will lapse to closer distances in mid-October.

The strange 1024 x 1024 pixel picture from today’s entrance is supposing below:
