Autor: B. Heber, G. Sarri, G. Wibberenz, C. Paizis, P. Ferrando, A. Raviart, A. Posner, R. Müller-Mellin, H. Kunow

Publikováno v: Annales Geophysicae, Vol 21, Pp 1275-1288 (2003)

Ulysses, launched in October 1990, began its second out-of-ecliptic orbit in December 1997, and its second fast latitude scan in September 2000. In contrast to the first fast latitude scan in 1994/1995, during the second fast latitude scan sola

An overview of Jovian electrons during the distant Ulysses Jupiter flyby

Autor: Reinhold Müller-Mellin, R. B. McKibben, Ming Zhang, Bernd Heber, Richard G. Marsden, Stefan Ferreira, C. Paizis, H. Kunow, M. S. Potgieter, Silvia Dalla, G. Wibberenz, G. Sarri

Publikováno v: Planetary and Space Science. 55:1-11

Since the 1970's interplanetary electrons in the MeV energy range, of Jovian origin, have been extensively studied from close to the Sun to beyond the Kronian orbit, near the ecliptic. The Ulysses trajectory allowed to study the propagation of these

Multi‐Spacecraft Observations of Solar Flare Particles in the Inner Heliosphere

Autor: Hilary V. Cane, G. Wibberenz

Publikováno v: The Astrophysical Journal. 650:1199-1207

For a number of impulsive solar particle events we examine variations of maximum intensities and times to maximum intensity as a function of longitude, using observations from the two Helios spacecraft and near the Earth. We find that electrons in th

The Ulysses trajectory provides a unique opportunity to study the propagation of MeV electrons in a wide range of heliographic latitudes and during varying conditions in the inner heliosphere. In recent papers we reported Ulysses Kiel Electron Telesc

Publikováno v: Geophysical Research Letters. 26:2133-2136

According to standard drift dominated modulation models the intensity variations of galactic cosmic ray protons and electrons respond differently to the latitudinal extension of the heliospheric current sheet α. In an A>0 solar cycle intensities of

A 22-year dependence in the size of near-ecliptic corotating cosmic ray depressions during five solar minima

Autor: Ian G. Richardson, Hilary Cane, G. Wibberenz

Publikováno v: Journal of Geophysical Research: Space Physics. 104:12549-12561

Evidence is presented for a 22-year cycle in the amplitude of recurrent, near-Earth, near-Ecliptic, galactic cosmic ray modulations during the solar minimum periods in the mid-1950s to mid-1990s. These modulations are ∼50% larger during A > 0 epoch

Cosmic ray modulation and the solar magnetic field

Autor: T. T. von Rosenvinge, Ian G. Richardson, G. Wibberenz, Hilary V. Cane

Publikováno v: Geophysical Research Letters. 26:565-568

We show that the variations of the interplanetary magnetic field strength (B) over a 22-year period are tracked by the inverted profile of the cosmic ray density measured by neutron monitors. We suggest that global changes in the Sun's magnetic field
