Rosetta a soli 51 Km dalla cometa 67P

Four-image NAVCAM montage comprising images taken on 7 September from a distance of 51 km from comet 67P/C-G

Four image montage of comet 67P/C-G, using images taken on 7 September. The four images are shown separated by black borders and there is some overlap between adjacent frames, so that some features appear in more than one image; the montage has been cropped to remove most of the black space around the comet.

Regular followers of this blog are familiar with how NAVCAM image sequences are now being taken, but you can read more about it in previous blog posts: CometWatch update, Make a NAVCAM mosaic and CometWatch – 2 September.
As before, we invite you to create a mosaic using these four images (posted below as individual JPEGs of the four 1024 x 1024 pixel full-frame ‘corners’). An example, with some adjustment of the intensity and cleaning of the background noise, is shown here:

We wish to thank again those of you who produced and shared your mosaics using images from the CometWatch updates posted last week. You are welcome to post your efforts on your personal profiles with the ESA/Rosetta/NAVCAM credit line, and share a link to your work in the comments box below.
