"Now that Rosetta has been able to safely approach Comet67P/Churyumov-Gerasimenko again following the active months around perihelion last August, scientists have been able to better image the southern hemisphere regions of the comet. This week the spacecraft is around 35 km distance from the nucleus, meaning that the OSIRIS narrow-angle camera can image the comet's surface with a resolution of around 80 cm/pixel." http://blogs.esa.int/rosetta/2016/02/24/getting-to-know-the-comets-southern-hemisphere/
