Kinetic Properties of Heavy Ions in the Solar Wind from SWICS/Ulysses
The kinetic properties of heavy ions in the solar wind are known to behave in a well organized way under most solar wind flow conditions: Their speeds are all equal and faster than that of hydrogen by about th...

Fractionation of SI, NE, and MG Isotopes in the Solar Wind as Measured by SOHO/CELIAS/MTOF
Using the high-resolution mass spectrometer CELIAS/MTOF on board SOHO we have measured the solar wind isotope abundance ratios of Si, Ne, and Mg and their variations in different solar wind regimes with bulk velo...

The Solar Minimum Active Region 7978, Its X2.6/1B Flare, CME, and Interplanetary Shock Propagation of 9 July 1996
The first X-class flare in four years occurred on 9 July 1996. This X2.6/1B flare reached its maximum at 09:11 UT and was located in active region 7978 (S10° W30°) which was an old-cycle sunspot polarity group...

Lower Cut-Off Energy Of 3He-Rich Solar Particle Events ?
Two 3He- and Fe-rich impulsive solar particle events, measured by the SMS-experiment on the WIND-S/C., were studied at the low energy end of their spectrum (0.5- 225 keV/e) which could not be reached by other exp...
