CometWatch – 19 September
Four image NAVCAM montage comprising images taken in the early hours of this morning, 19 September, from a distance of 28.6 km from the centre of Comet 67P/Churyumov-Gerasimenko. For comparison, recall the OSIRIS image taken on 3 August from a distance of 285 km.
A mosaic, and the four individual frames are also provided below.
This beautiful view shows off a wide range of the comet's features: from the jets emanating from the ‘neck’ region, to the steep cliffs towering over both smooth and grooved terrain, and to the hundreds of boulders scattered across the surface.
The mosaic has been put together using Microsoft ICE. This left a few small regions requiring slight exposure adjustments using Adobe LightRoom. The full image has then been lightly contrast enhanced to bring out the activity without increasing the background noise too much.
The original images are unaltered and can be used for comparison.
