We present some results of the analytical integration of the energy rate balance equation, assuming that the input energy rate is proportional to the azimuthal interplanetary electric field, Ey, and can be described by simple rectangular or triangula

We describe the preliminary design of a magnetograph and visible-light imager instrument to study the solar dynamo processes through observations of the solar surface magnetic field distribution. The instrument will provide measurements of the vector

A large number of magnetic clouds (MCs) were observed during the operation period of the Helios mission. Some of the MCs were observed by multi-spacecraft, enabling a detailed study of their extension in the inner heliosphere when they pass by more t

Extreme historical and space era geomagnetic storms ( Δ H or Dst ≤ − 400 nT ) are studied in terms of their sunspot and Gleissberg solar cycle distributions. Interplanetary and magnetospheric processes associated with the Carrington storm are su

For over an entire solar cycle, from the end of 1974 until the beginning of 1986, the twin Helios spacecraft explored the inner heliosphere. These in situ, high-resolution plasma and magnetic field measurements covered heliocentric distances between

Geomagnetic storms are intervals of time when a sufficiently intense and long-lasting interplanetary convection electric field leads, through a substantial injection of energy into the magnetosphere-ionosphere system, to an intensified ring current,

From the analysis of different sets of magnetic clouds and focusing on the most probable value found for the peak amplitude of their negative B z fields, we present an estimate for the peak intensity of the associated geomagnetic storms (peak Dst ).

For a set of 11 magnetic cloud events, the time-integrated values of the injection function necessary to observe variations in the Dst index at levels of −50, -75, -100, -125 and −150 nT have been estimated. A study of the average values of magne

The annual distribution of geomagnetic activity is studied through the geomagnetic indices Aa, Dst and AE, according to different levels of intensity for each of the indices. It is shown that the well known pattern of seasonal variation, with maxima

The study of the response of the magnetosphere, measured by the Dst index, to different interplanetary magnetic field configurations observed in magnetic clouds has led us to conclude that about 20% of intense magnetic storms have the growth of their
