    Interface structure of co-rotating interaction regions

    , European Space Agency Special Publication ESA SP, Pages: 59-65, ISSN: 0379-6566

    Plasma and particle observations on Ulysses during its passes through the southern and northern heliosphere have revealed that, inside the streamer belt, the large-scale structure of the quiet global heliosphere is dominated by corotating interaction regions (CIRs). Therefore, considerable attention is now being given to the internal plasma structure of CIRs, and in particular, to the mainfestations of the stream interfaces that should mark their origins as interactions between low speed solar wind (in the low-latitude streamer belt) and high speed solar wind (from the equatorial extensions of the high latitude polar coronal holes). The SWICS and HI-SCALE experiments on Ulysses combine plasma and energetic particle measurements that are of considerable utility for such studies because, between them, they cover the proton energy range from 10 eV to 5 MeV. We use these measurements, together with magnetic field data, to study the remarkable series of CIRs that occurred during the period beginning July 1992 and the end of 1993 as Ulysses rose from the ecliptic to a southern heliographic latitude of 48 degrees. We make use of the identification of interfaces recently published by Wimmer-Schweingruber et al., 1997. The structure of the regions between the forward and reverse shocks has previously been analyzed in terms of the proton specific entropy argument log (n/T<sup>3/2</sup>) that should exhibit a discontinuous jump at the stream interface. It has been claimed that the stream interface, defined with respect to specific entropy, is also associated with a discontinuity in energetic proton intensities. This paper examines the energetic particle data (> 60 keV) and how they were ordered with respect to interfaces and with respect to the magnetic field.

    Spatial evolution of 26-day recurrent galactic cosmic ray decreases: Correlated Ulysses cospin/KET and SOHO COSTEP observations

    , European Space Agency Special Publication ESA SP, Pages: 331-336, ISSN: 0379-6566

    In December 1995 the Ulysses spacecraft was at a radial distance of 3 AU from the Sun and 60° northern heliographic latitude. To that time the Solar and Heliospheric Observatory (SOHO) started its mission. On board of both spacecraft particle sensors are measuring electrons, protons and helium nuclei in the MeV to GeV energy range. In early 1996 the counting rates of several hundred MeV galactic cosmic rays at Ulysses and at SOHO (Earth orbit) were modulated by recurrent cosmic ray decreases (RCRDs). The RCRDs at SOHO were found to be associated with a corotating interaction region (CIRs). A Lomb (spectral) analysis was performed on the galactic cosmic ray flux from February 1996 to June 1996. Surprisingly, the most probable frequency is ∼28 days and not 26 or 27 days, corresponding to one solar rotation. The amplitude of the RCRDs is ∼2.3% on both spacecraft. The variation in the solar wind speed shows the same periodicities and is anticorrelated to the variation in the cosmic ray flux (see Richardson et al. 1996). In contrast to the RCRDs the amplitude found in the solar wind speed is four times larger at WIND (120 km/s) than at Ulysses (32 km/s). The solar wind proton density and magnetic field strength yielded no significant periodicities, neither at Ulysses nor at WIND. Comparing the RCRDs with coronal hole structures observed in the FE XIV line, we found that a single coronal hole close to the heliographic equator can account for the RCRDs observed "simultaneously" at Ulysses and SOHO. The coronal hole boundaries changed towards lower Carrington longitudes and vanished slowly. The changes of the boundaries during the investigated period could explain a 28 day periodicity.
