Rosetta blog: CometWatch 26 Oct – 6 hours apart

CometWatch this week comprises dual NAVCAM images acquired 6 hours detached on 26 Oct 2015.

The images have been easily extended to exhibit some fact of a comet’s activity (the unprocessed images are accessible during a finish of a post). In a 6 hours that upheld Rosetta also changed 2.3 kilometres closer to a comet, ensuing in somewhat opposite picture beam between a dual images.


Caption: Left: Comet 67P/C-G during 13:31:01 UT on 26 Oct from a stretch of 312.7 km. The picture scale is 26.6 m/pixel and a picture measures 27.3 km across. Right: The perspective 6 hours later, during 19:27:53 UT, from a stretch of 310.4 km. The picture scale for a second picture is 26.5 m/pixel and a picture measures 27.1 km.

Since Comet 67P/Churyumov-Gerasimenko’s revolution duration is a tiny over 12 hours, these dual images are distant by about half a comet rotation, charity interrelated views of a nucleus. In both orientations, jets can be seen rising from a sunlit side of a nucleus.

In a left-hand picture a vast lobe is in a foreground, with Imhotep confronting a viewer, despite mostly in shadow. Similarly, a outline of a Aten depression, also in shadow, can only be done out to a right. Above Aten, towards a centre of a image, are a Khepry and Aker regions, with Anhur towards the top left of a vast lobe.

On a tiny lobe in a credentials it is mostly Bastet that is visible, with a spirit of Wosret appearing as a prosaic apportionment at the top left.

Six hours after and a comet’s tiny lobe is in a foreground, a vast lobe in a background, with a Anuket segment of a comet’s neck manifest in between. On a vast lobe a shallow separating Seth (itself not visible) from a well-spoken Anubis segment can be straightforwardly picked out, appearing as a arc-shaped underline on a reduce right corner of a vast lobe; Seth is in fact underneath it, expel in shadow. The some-more imperishable Atum and tools of Khonsu can be seen beyond, in a top partial of a image.

Meanwhile a severe turf on a tiny lobe contains tools of Serqet, Nut, Ma’at and Maftet, with Wosret to a distant left.

If you’re anticipating it tough to navigate, afterwards do check out a interactive comet viewer alongside a CometWatch posts and toggle a regions on and off.

In other CometWatch news, 1003 images were combined into a NAVCAM Archive Image Browser yesterday. They cover a duration 11 March–5 May 2015 and embody images from a 14 km tighten flyby on 28 March. Enjoy!
