The features of microwave solar radiation observed in the stage of formation and initial propagation of geoeffective coronal mass ejections
Sheiner, O. A.; Fridman, V. M.
We consider sporadic radio emission which precedes recording of geoeffective coronal mass ejections, using the data of broadband patrol observations of the Sun in the centimeter-, decimeter-, and meter-wave ranges in some periods of the XXIst-XXIIIrd solar-activity cycles. The total amount of used information instruments covers 339 events and incl…
High-latitude and polar heliosphere
Veselovsky, I. S.
A short review of the recent studies of the three-dimensional structure of the heliosphere is presented. The main progress is due to direct plasma and magnetic field measurements from the Ulysses spacecraft outside the ecliptic plane in heliolatitudes of up to ±80°. The new data are used for the development of theoretical models.
