The Ring-Moon Systems Node of NASA's Planetary Data System (PDS) is devoted to archiving, cataloging, and distributing scientific data sets relevant to planetary systems, including planets, rings, and moons and the ways they interact.

Earth-Based Uranus System Stellar Occultations
  • We have archived more than 50 data bundles of Earth-based observations of stellar occultations of the Uranus system.
  • Each bundle corresponds to a single occultation-telescope combination. These represent the highest quality observations spanning 25 years beginning with the ring system discovery observations by the Kuiper Airborne Observatory in 1977.
  • Users are strongly encouraged to review the associated support bundle which includes a comprehensive Users Guide as well as models of the individual Uranian rings.
  • To download the entire set in a single TAR.GZ file, click here.
