Solar and Heliospheric Phenomena in October-November 2003: Causes and Effects
Petrukovich, A. A.; Zelenyi, L. M.; Yermolaev, Yu. I. +72 more
We present new observational data on the phenomena of extremely high activity on the Sun and in the heliosphere that took place in October-November 2003. A large variety of solar and heliospheric parameters give evidence that the interval under consideration is unique over the entire observation time. Based on these data, comparing them with simil…
Sporadic plasma streams and their sources in the period of extraordinary solar activity from October 26 to November 6, 2003
Eselevich, M. V.; Eselevich, V. G.
Based on the results of investigations made by various authors applying different semiempirical models, we have formulated the principles of a complex method that allows one to associate sporadic streams of the solar wind (SW) at the Earth’s orbit with coronal mass ejections (CMEs), which are their sources on the Sun. This method is applied to an …
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…
Statistical Relationships between Solar, Interplanetary, and Geomagnetic Disturbances, 1976-2000: 3
Yermolaev, Yu. I.; Yermolaev, M. Yu.
In this paper we continue the analysis of the influence of solar and interplanetary events on magnetic storms of the Earth that was started in [9, 10]. Different experimental results on solar-terrestrial physics are analyzed in the study and the effects are determined that arise due to differences in the methods used to analyze the data. The class…
The Whisper Relaxation Sounder Onboard Cluster: A Powerful Tool for Space Plasma Diagnosis1, 2 around the Earth
Décréau, P. M. E.; Canu, P.; Darrouzet, F. +3 more
The WHISPER relaxation sounder that is onboard the four CLUSTER spacecraft has as its main scientific objectives to monitor the natural waves in the 2 kHz-80 kHz frequency range and, mostly, to determine the total plasma density from the solar wind down to the Earth's plasmasphere. To fulfill these objectives, the WHISPER uses the two long double …
Statistical Relationships between Solar, Interplanetary, and Geomagnetospheric Disturbances, 1976-2000
Yermolaev, Yu. I.; Yermolaev, M. Yu.
Within the framework of the Space Weather program, 25-year data sets for solar X-ray observations, measurements of plasma and magnetic field parameters in the solar wind, and D_st index variations are analyzed to reveal the factors that have had the greatest influence on the development of magnetospheric storms. The correlation between solar flare…
