Frequency fluctuations of coherent signals from spacecraft observed during dual-frequency radio sounding of the circumsolar plasma in 2004-2008

Pätzold, M.; Bird, M. K.; Efimov, A. I. +4 more

We have performed spectral processing of the data of experiments on radio sounding of circumsolar plasma by coherent S- and X-band signals from the spacecraft Ulysses, Mars Express, Rosetta, and Venus Express carried out from 1991 to 2009. The experiments were realized in the mode of coherent response, when a signal stabilized by the hydrogen stan…

Intensity enhancements of 200-2000 MeV protons in 1997-2005 as measured by the KET/ULYSSES

Reflection Model as Applied for the Analysis of Enhancements of Solar Cosmic Rays at Different Heliocentric Distances: An Example of the Event Observed in June 1991 onboard GRANAT and ULYSSES Spacecraft

Grigorenko, E. E.; Lyubimov, G. P.

In this paper we consider a large-scale enhancement of the intensity of solar protons (E = 1-20 MeV) observed in June 1991 for 26 days at different points of interplanetary space, onboard ULYSSES (in the time period under consideration it was located at a heliocentric distance of 3 AU, at an angular distance of ~70° to the East of the Sun-Earth li…
