Out of the shadow – CometWatch 9 March

Today’s CometWatch entry was captured on 9 March at a distance of 71.9 km from the centre of Comet 67P/Churyumov-Gerasimenko. The scale is 6.1 m/pixel and the image measures 6.3 km across (note that the processed version...

False colour image showing the smooth Hapi region connecting the head and body of comet 67P/Churyumov-Gerasimenko. Differences in reflectivity have been enhanced in this image to emphasise the blueish color of the Hapi region. The scientific data was acquired on 21 August 2014 by the scientific imaging system OSIRIS with the filters centred at 989, 700 and 480 nanometres. During these observations Rosetta was 70 km far away from the comet, and the corresponding spatial resolution 1.3m/pixels.
