Ulysses charged particle measurements between 1 and 5 AU from the sun

Smith, E. J.; Wenzel, K. -P.; Page, D. E.

Proton fluxes obtained by two instruments carried on the ESA/NASA Ulysses spacecraft are reported for the period from launch in October 1990 till Jupiter encounter in February 1992. Proton energy ranges are 24-59, 71-99, 130-320, 320-2100 and > 2100 MeV. The Sun was very active during this period, the events of March 1991 being some of the larg…

Observations of the solar corona with ulysses: Expectations above the polar regions

Marsden, R. G.; Wenzel, K. -P.

During its prime mission phase, the Ulysses space probe will fly above both solar poles, providing an unprecedented opportunity to study the high latitude regions of the solar corona. The timing of the polar passes (mid-1994 and mid-1995) coincides with solar minimum, corresponding to a coronal configuration consisting of well-developed polar coro…
