Study of distribution functions of interplanetary particles accelerated at co-rotating interaction region at∼5A.U.

Lanzerotti, L. J.; Maclennan, C. G.

We report the results of a study of the 12-hour average distribution functions of high Z nuclei as measured over a 10-day interval on the Ulysses spacecraft at a helioradius of∼5.2 A.U. We use the good time and atomic mass resolution of the composition aperture of the HI-SCALE instrument to determine the form of the distribution functions for C, O…

The Evolution of the Anomalous Component of the Cosmic Rays During the ULYSSES Mission

Sanderson, T. R.; Marsden, R. G.; Trattner, K. J. +1 more

We have studied the evolution of the anomalous cosmic ray component at ULYSSES using observations of the quiet time helium fluxes obtained with the COSPIN Low Energy Telescope during the years from launch in October 1990 to the latest data in 1994. Shown are preliminary results of measurements in the energy range from 4.0 to 19 MeV/n. Following th…

Polar Rain Entry of Galactic Electrons into the Inner Heliosphere?

Christian, E. R.; Cooper, J. F.

The understanding of the relative intensity variations in cosmic ray ions and electrons with respect to solar modulation is a grand challenge for cosmic ray modulation theory. Although effects of the heliospheric neutral sheet, gradient-curvature drifts, and merged interaction regions provide qualitative explanations for observed solar cycle varia…

Ulysses' Race to the Pole: Symposium Summary

Lee, Martin A.

This paper reproduces the Symposium Summary presentation at the 28th ESLAB Symposium on The High Latitude Heliosphere. The summary is not comprehensive but with considerable latitude covers the highlights of the conference. Featured are the observations of the high-speed wind from the growing southern polar coronal hole, new measurements of the in…
