The ESA/NASA spacecraft Ulysses is making, for the first time, direct measurements in the solar wind originating from virtually all places where the corona expands. Since the initial two polar passes of Ulysses occur during relatively quiet solar conditions, we discuss here the three main regimes of quasi-stationary solar wind flow: the high speed streams (HSSTs) coming out of the polar coronal holes, the slow solar wind surrounding the HSSTs, and the streamers which occur at B-field reversals… 

Radial evolution of the solar wind in pure high-speed streams: HELIOS revised observations

Spacecraft observations have shown that the proton temperature in the solar wind falls off with radial distance more slowly than expected for an adiabatic prediction. Usually, previous studies have

Solar Wind Models from the Sun to 1 AU: Constraints by in Situ and Remote Sensing Measurements

There are three major types of solar wind: The steady fast wind originating on open magnetic field lines in coronal holes, the unsteady slow wind coming probably from the temporarily open streamer

‘ 4 The three-dimensional solar wind at solar activity minin

In late 1997, the Ulysses spacecraft completed its first orbit around the Sun, observing the properties of the heliosphe.re at all latitudes between 80°S and 80°N. Because the mission occurred during

The three‐dimensional solar wind at solar activity minimum

In early 1998 the Ulysses spacecraft made history by completing an orbit around the Sun inclined to the solar equator by 80°. It observed the properties of the high‐latitude heliosphere at a time of

Origins and properties of the quasi-stationary slow solar wind

Comparisons of the brightness distributions of the white corona observed at distances of several solar radii with solar wind velocities derived from interplanetary-scintillation observations, as well

Slow Solar Wind: Observations and Modeling

While it is certain that the fast solar wind originates from coronal holes, where and how the slow solar wind (SSW) is formed remains an outstanding question in solar physics even in the post-SOHO

Origins of the Ambient Solar Wind: Implications for Space Weather

The Sun’s outer atmosphere is heated to temperatures of millions of degrees, and solar plasma flows out into interplanetary space at supersonic speeds. This paper reviews our current understanding of

Comparison of algorithms for determination of solar wind regimes

This study compares the designation of different solar wind flow regimes (transient, coronal hole, and streamer belt) according to two algorithms derived from observations by the Solar Wind Ion


The origin and acceleration of the solar wind are still debated. In this paper, we search for signatures of the source region and acceleration mechanism of the solar wind in the plasma properties



Solar Wind Composition and What We Expect to Learn from Out-of-Ecliptic Measurements

Elemental abundances in the solar wind are fractionated relative to the solar abundances by atom-ion separation in the upper chromosphere and by ion-ion separation in the corona, where also the

A coronal hole and its identification as the source of a high velocity solar wind stream

X-ray images of the solar corona, taken on November 24, 1970, showed a magnetically open structure in the low corona which extended from N20W20 to the south pole. Analysis of the measured X-ray

The solar wind ion composition spectrometer

The Solar Wind Ion Composition Spectrometer (SWICS) on Ulysses is designed to determine uniquely the elemental and ionic-charge composition, and the temperatures and mean speeds of all major

High coronal structure of high velocity solar wind stream sources

When solar wind plasma in the trailing (eastern) edge of a high-speed stream is mapped back to its estimated source in the high corona using the constant radial velocity (EQRH) approximation, a large

Evidence for a structure‐free state at high solar wind speeds

A statistical study has been made of the variability of the basic solar wind flow parameters in high- and low-speed flows. Care was taken to exclude data taken during positive speed gradients, where

Solar wind helium and hydrogen structure near the heliospheric current sheet: A signal of coronal streamers at 1 AU

We have investigated solar wind flow properties associated with very low helium to hydrogen abundance ratios (A(He)) observed with Los Alamos instrumentation on IMP 6, 7, and 8 during the 1971 - 1978
