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.
