| Abstract: | Some excellent photographs of Saturn in yellow and violet light have been taken in 1969 with the 105cm reflecting telescope of the Pic du Midi Observatory. They revealed the existence, inside the C-ring, of an extremely faint, fourth Ring. The reduction of microphotometric tracings along the great-axis of the Rings, have given the photometric curves of the rings in the two colours above. These two curves are very similar. They do not agree with some of the details drawn before and show some new ones. |
