Changes in One Area on the Larger Sphere of 67P/C-G
This image is comparing and showing changes in the feature informally named "The Equatorial Plain" between the dates of 6 Aug 14 and 23 Aug 14. During this time interval numerous depressions and mounds in the range of 5 to 6 meters have appeared. The source and provenance of these features is unknown. However, it seems not likely that this many small impact craters have been formed or boulders emplaced, so the origin is intriguing and mysterious.
NOTE: most likely the "features" are pre-processing artifacts. OOPS. :)
This area is a likely source of the large, broad dust jet seen to the lower left of the 2 Sept 14 image of the dust jets.
