Analysis of Plasma and Field Conditions during Some Intensely Geoeffective Transient Solar/Interplanetary Disturbances of Solar Cycle 23
Earth:geomagnetic storm Sun:solar and wind magnetosphere coupling
font style='font-size:12px;'>
2009/5/7
The problem of solar wind-magnetosphere coupling is investigated for intense geomagnetic storms (Dst γ -100 nT) that occurred during solar cycle 23. For this purpose interplanetary plasma and fie...

2009/5/6
Magnetic field in the solar interior contributes to the even order
splitting coefficients, but it is not possible to separate the effect of magnetic
field from those due to other deviations from sph...

2009/5/6
In this paper, we study the evolution of vector magnetic
field of AR 10656 by using the observations of Huairou Solar Observing
Station (HSOS, China) and Big Bear Solar Observatory (BBSO, USA).
