What is that radial dark area in the C3 images at about the 7 oclock position ?
The 7 o’clock position is where the pylon that holds the occulting disk appears in the image. It has always been in the images. The C2 camera also has a pylon in the 7 o’clock position but it is less obvious than the C3 pylon due to a different optical design. The occulting disk and arm is similiar to what a person does when they want to look at something close to the sun; they hold up their hand and block the disk of the sun.
