Solar Cycle Propagation, Memory, and Prediction: Insights from a Century of Magnetic Proxies
(IOP Publishing, 2013-04-02)
The solar cycle and its associated magnetic activity are the main drivers behind changes in the interplanetary environment and Earth’s upper atmosphere (commonly referred to as space weather). These changes have a direct ...
Properties of Magnetic tongues over a Solar Cycle
(Springer, 2016-05)
The photospheric spatial distribution of the main magnetic polarities of bipolar
active regions (ARs) present during their emergence deformations are known as magnetic tongues. They are attributed to the presence of twist ...
Resultados preliminares de la investigación de las explosiones solares en banda centimétrica
(1983)
Se hace un estudio estadístico de las explosiones solares. Se establece una clasificación para las mismas, en la banda de 1-21 cm, basada en los espectros observados en esta banda, y se presentan las asociaciones de estas ...
Magnetic cloud models with bent and oblate cross-section boundary
(EDP Sciences, 2009-09-15)
Context. Magnetic clouds (MCs) are formed by magnetic flux ropes that are ejected from the Sun as coronal mass ejections. These structures generally have low plasma beta and travel through the interplanetary medium interacting ...
The Counterkink Rotation of a Non-Hale Active Region
(IOP Publishing, 2000-11)
We describe the long-term evolution of a bipolar non-Hale active region that was observed from 1995 October to 1996 January. During these four solar rotations the sunspots and subsequent flux concentrations, during the ...
Quantifying and specifying the solar influence on terrestrial surface temperature
(Elsevier, 2010-08)
This investigation is a follow-up of a paper in which we showed that both major magnetic components of the solar dynamo, viz. the toroidal and the poloidal ones, are correlated with average terrestrial surface temperatures. ...
Initiation of CMEs: the role of magnetic twist
(Elsevier, 2000-11)
Recent multiwavelength observations, modelling results and theoretical developments indicate the importance of twisted magnetic configurations in solar active regions (ARs) in the initiation of coronal mass ejections (CMEs). ...
The role of magnetic bald patches in surges and arch filament systems
(EDP Sciences, 2002-08)
The short-lived active region (AR) NOAA 7968 was thoroughly observed all along its disk transit (June 3 to 10, 1996) from space and from the ground. During the early stage of its evolution, flux emerged in between the two ...
Statistical analysis of discontinuities in solar wind ace data and comparison with intermittent mhd turbulence
(IOP Publishing, 2009-12)
The comparison between Advanced Composition Explorer (ACE) solar wind data and simulations of magnetohydrodynamic (MHD) turbulence shows a good agreement in the waiting-time analysis of magnetic field increments. Similarity ...
Spatial characterization of a flare using radio observations and magnetic field topology
