Rosetta-- Comparative Series
Read MoreComparative series of images: North Polar Plain active jet area
This is a comparative series of NavCam images centered on a feature informally named "The North Polar Plain" located near 90 degrees latitude. It is centered on the area suspected to be the source of the prominent collimated dust jet. The line of "boulders" is informally known as "The Necklace".

This is an updated comparative series of images centered on a feature informally named "The Equatorial Plain" located near 0 degrees longitude on the large sphere of the comet. It shows this feature on the dates of 6 August, 13 August, 15 August, 23 August, 7 September 14 and 8 October 14 with the OSIRIS imager or the NavCam. The images are presented in a similar scale of 1 meter per pixel and with a similar orientation.
Comparison of Vents near Site J with recent imagery
The ESA Press briefing on 15 Sep14 mentioned possible vents near Site J.
I have been following these with the hope of detecting changes, but nothing, within the resolution of the imagery,
has been seen.
The first of "Ten at 10" series of images happens to show this study area at a distance of 9.9 Km and a scale of 0.6 M/pixel. In this image, the scalloped surface to the right of the lefthand vent may be a deflationary feature caused by gas outflow. We'll know more as time goes on because the comet can only get more active.
I have incorporated this image with some earlier images of the comparative series, including one cross-eyed OSIRIS stereo pair.

A comparison of the Imhotep (informally named "Equatorial") Plain of the Larger Lobe: OSIRIS image 6 August 2014 and NAVCAM image 3 January 2015. Note that there are differences in the lighting angles and viewing geometries. The scale is adjusted to approximately 2.5 m/Pixel.
