Saturn-like system around Uranus

It is stated that observations made at Kavalur (India) of the occultation of SAO158687 by Uranus on 10 March 1977 showed, in addition to the occultation by a satellite system termed the epsilon ring, a dimming of the light of the star close to the time when the atmosphere of the planet could have caused the phenomenon. Since then, the identities of the α β γ delta rings have also become well established, and a theoretical interpretation of their origin has been proposed. A close examination of the Kavalur photoelectric record is here described and several new features of the satellite ring system of Uranus are noted. (author)
