CICLOPS has released this processed view of Rhea's leading hemisphere taken on June 2 from a distance of 1.8 million km (for a resolution of 11 km/pixel, though this view has been magnified 2x to improve feature visibility). This image shows a range of impact phenomena on the surface of Rhea. On the right side of the disk, we can see the now famous ray crater as well as many as two large impact basins near the terminator. The northern impact basin is Tirawa which was measured using this image as being 360 km across (+/- 20 km). There is a second impact basin south of Tirawa more in the shadows, which is at least as large as Tirawa
Phil mentioned a third impact basin 1 basin width south of the southern basin. Maybe Phil can correct me here but I think he is talking about the circular ring seen here near the terminator 1 basin width south of the "southern" basin.
