Note the large number of faint objects orbiting near the F ring. These include objects S5, S6, and S7 announced by the HST team. Both S5 and S7 were also detected with AO, whereas S6 falls in a region that was not observed. S13 was later confirmed by the HST team.

Janus and the tip of the bright rings are on the right. Note the foreshortening of the arc as it approaches maximum elongation. Given the success of curvature AO, the CFHT Corporation built a 19-actuator user AO system based on the same technique. Previous searches for asteroidal satellites with both ground-based telescopes and HST had failed. The NEAR space probe that was recently put into orbit around EROS has not found yet a companion.
