On-line access to the heliospheric measurements at high latitudes using the ESA archive for ULYSSES data

Abstract

Ulysses is currently making its second orbit of the Sun, having successfully provided unique and continuous measurements of heliospheric particles and fields as a function of heliographic latitude during its first passes of the solar polar regions. The new measurements will give an insight into the dynamics of the heliosphere at solar maximum, in contrast to the observations already made during the declining phase of the last solar cycle and at solar minimum. The ESA archive for Ulysses data provides on-line access to measurements made by the spacecraft. The status of the archive is discussed and the existing data sets are catalogued. A description of access procedures is provided and useful ancillary applications are described.
