Suddenly the questions came to me. No one saw this before? How can a 31 km diameter structure not be noticed? So I decided to explore around for a while to check for similar structures.You can check it out over here.
Just passed the Libyan border entering Chad at 121 miles "flying" high when another circular structure appeared in my screen. A closer look was showing, apparently, a typical impact structure, not volcanic. Of course, finding an impact crater has no merit if it is an already known one, so I had to check and visited the Canadian Brunswick University impact crater database, in Canada, and none of the listed matched my discovery.
