A numerical mapping of energy gains in a powered Swing-By maneuver
(Springer, 2017-07-01)
The present paper studies the effects of a powered Swing-By maneuver, considering the particular and important situations where there are energy gains for the spacecraft. The objective is to map the energy variations ...
Interplanetary flux rope ejected from an X-ray bright point: The smallest magnetic cloud source-region ever observed
(EDP Sciences, 2005-12)
Using multi-instrument and multi-wavelength observations (SOHO/MDI and EIT, TRACE and Yohkoh/SXT), as well as computing the coronal magnetic field of a tiny bipole combined with modelling of Wind in situ data, we provide ...
Actors of the main activity in large complex centres during the 23 solar cycle maximum
(Elsevier, 2011-02)
During the maximum of Solar Cycle 23, large active regions had a long life, spanning several solar rotations, and produced large numbers of X-class flares and CMEs, some of them associated to magnetic clouds (MCs). This ...
How Can a Negative Magnetic Helicity Active Region Generate a Positive Helicity Magnetic Cloud?
(Springer, 2009-11-13)
The geoeffective magnetic cloud (MC) of 20 November 2003 was associated with the 18 November 2003 solar active events in previous studies. In some of these, it was estimated that the magnetic helicity carried by the MC had ...
Large scale MHD properties of interplanetary magnetic clouds
(Elsevier, 2005-12)
Magnetic Clouds (MCs) are the interplanetary manifestation of Coronal Mass Ejections. These huge astrophysical objects travel from the Sun toward the external heliosphere and can reach the Earth environment. Depending on ...
Unusually long lasting multiple penetration of interplanetary electric field to equatorial ionosphere under oscillating IMF Bz
(American Geophysical Union, 2008-01-17)
During November 11–16, 2003, the interplanetary magnetic field (IMF) Bz oscillated between northward and southward directions, which suggests discontinuous magnetic reconnection associated with the multiple pulses‐like ...
