Hello Hatmehit – CometWatch 18 January
January 28, 2015
Today’s CometWatch mosaic comprises images taken by Rosetta’s navigation camera (NAVCAM) on 18 January, from a distance of 28.4 km from the centre of Comet 67P/Churyumov-Gerasimenko. The image resolution is 2.4 m/pixel and the individual 1024 x 1024 frames measure 2.5 km across. The mosaic is slightly cropped and measures 3.7 x 4.0 km.
The mosaic focuses on the smaller of the comet’s two lobes, with the shallow, 1 km wide depression we now know to be called Hatmehit situated towards the top. Bordering Hatmehit are the Ma’at, Maftet and Bastet regions (refer to the maps here and here to get oriented with Comet 67P/C-G’s geography).
The flanks of the comet’s larger lobe can be seen in the background of this mosaic, while much of the foreground is dominated by shadow.
